for Translate() calls:\n\t///   * The type of the ResolveResult must match the StackType of the corresponding ILInstruction,\n\t///     except that the width of integer types does not need to match (I4, I and I8 count as the same stack type here)\n\t///   * Evaluating the resulting C# expression shall produce the same side effects as evaluating the ILInstruction.\n\t///   * If the IL instruction has <c>ResultType == StackType.Void</c>, the C# expression may evaluate to an arbitrary type and value.\n\t///   * Otherwise, evaluating the resulting C# expression shall produce a similar value as evaluating the ILInstruction.\n\t///      * If the IL instruction evaluates to an integer stack type (I4, I, or I8),\n\t///        the C# type of the resulting expression shall also be an integer (or enum/pointer/char/bool) type.\n\t///        * If sizeof(C# type) == sizeof(IL stack type), the values must be the same.\n\t///        * If sizeof(C# type) > sizeof(IL stack type), the C# value truncated to the width of the IL stack type must equal the IL value.\n\t///        * If sizeof(C# type) &lt; sizeof(IL stack type), the C# value (sign/zero-)extended to the width of the IL stack type\n\t///          must equal the IL value.\n\t///          Whether sign or zero extension is used depends on the sign of the C# type (as determined by <c>IType.GetSign()</c>).\n\t///      * If the IL instruction is a lifted nullable operation, and the underlying operation evaluates to an integer stack type,\n\t///        the C# type of the resulting expression shall be Nullable{T}, where T is an integer type (as above).\n\t///        The C# value shall be null iff the IL-level value evaluates to null, and otherwise the values shall correspond\n\t///        as with non-lifted integer operations.\n\t///      * If the IL instruction evaluates to a managed reference (Ref) created by starting tracking of an unmanaged reference,\n\t///        the C# instruction may evaluate to any integral/enum/pointer type that when converted to pointer type\n\t///        is equivalent to the managed reference.\n\t///      * Otherwise, the C# type of the resulting expression shall match the IL stack type,\n\t///        and the evaluated values shall be the same.\n\t/// </remarks>\n\tsealed class ExpressionBuilder : ILVisitor<TranslationContext, TranslatedExpression>\n\t{\n\t\tinternal

This shows the basics of using the NuGet.\n* **ILSpyCmd** project in the [ILSpy repository](https://github.com/icsharpcode/ILSpy/tree/master/ICSharpCode.ILSpyCmd). This dotnet tool shows automation of whole assembly decompilation.\n* **ILSpy.Backend** in the [ILSpy Visual Studio Code Extension repository](https://github.com/icsharpcode/ilspy-vscode/tree/master/backend). This LSP shows listing / decompiling members.\n* **ILSpy** itself. Complex, recommended only for advanced users and definitely **not** the place to get started.\n"

Note that `--outputdir .` directs the output to the current directory.\n\n### Automatically\n\nIf you want to deploy an up-to-date HTML diagrammer as part of your live documentation,\nyou'll want to automate its regeneration to keep it in sync with your code base.\n\nFor example, you might like to share the diagrammer on a web server or - in general - with users\nwho cannot or may not regenerate it; lacking either access to the ilspycmd console app or permission to use it.\n\nIn such cases, you can dangle the regeneration off the end of either your build or deployment pipeline.\nNote that the macros used here apply to [MSBuild](https://learn.microsoft.com/en-us/visualstudio/msbuild/msbuild) for [Visual Studio](https://learn.microsoft.com/en-us/visualstudio/ide/reference/pre-build-event-post-build-event-command-line-dialog-box) and your mileage may vary with VS for Mac or VS Code.\n\n#### After building\n\nTo regenerate the HTML diagrammer from your output assembly after building,\nadd something like the following to your project file.\nNote that the `Condition` here is optional and configures this step to only run after `Release` builds.\n\n```xml\n<Target Name=\"PostBuild\" AfterTargets=\"PostBuildEvent\" Condition=\"'$(Configuration)' == 'Release'\">\n  <Exec Command=\"$(SolutionDir)..\\path\\to\\ilspycmd.exe $(TargetPath) --generate-diagrammer --outputdir $(ProjectDir)diagrammer\" />\n</Target>\n```\n\n#### After publishing\n\nIf you'd rather regenerate the diagram after publishing instead of building, all you have to do is change the `AfterTargets` to `Publish`.\nNote that the `Target` `Name` doesn't matter here and that the diagrammer is generated into a folder in the `PublishDir` instead of the `ProjectDir`.\n\n```xml\n<Target Name=\"GenerateHtmlDiagrammer\" AfterTargets=\"Publish\">\n  <Exec Command=\"$(SolutionDir)..\\path\\to\\ilspycmd.exe $(TargetPath) --generate-diagrammer --outputdir $(PublishDir)diagrammer\" />\n</Target>\n```\n\n### Usage tips\n\n**Compiler-generated** types and their nested types are **excluded by default**.\n\nConsider sussing out **big source assemblies** using [ILSpy](https://github.com/icsharpcode/ILSpy) first to get an idea about which subdomains to include in your diagrammers. Otherwise you may experience long build times and large file sizes for the diagrammer as well as a looong type selection opening it. At some point, mermaid may refuse to render all types in your selection because their definitions exceed the maximum input size. If that's where you find yourself, you may want to consider\n- using `--generate-diagrammer-include` and `--generate-diagrammer-exclude` to **limit the scope of the individual diagrammer to a certain subdomain**\n- generating **multiple diagrammers for different subdomains**.\n\n### Advanced configuration examples\n\nAbove examples show how the most important options are used. Let's have a quick look at the remaining ones, which allow for customization in your project setup and diagrams.\n\n#### Filter extracted types\n\nSometimes the source assembly contains way more types than are sensible to diagram. Types with metadata for validation or mapping for example. Or auto-generated types.\nEspecially if you want to tailor a diagrammer for a certain target audience and hide away most of the supporting type system to avoid noise and unnecessary questions.\n\nIn these scenarios you can supply Regular Expressions for types to `--generate-diagrammer-include` (white-list) and `--generate-diagrammer-exclude` (black-list).\nA third option `--generate-diagrammer-report-excluded` will output a `.txt` containing the list of effectively excluded types next to the HTML diagrammer containing the effectively included types.\n\n<pre>\nilspycmd.exe <b>--generate-diagrammer-include Your\\.Models\\..+ --generate-diagrammer-exclude .+\\+Metadata|.+\\.Data\\..+Map --generate-diagrammer-report-excluded</b> ..\\path\\to\\your\\assembly.dll --generate-diagrammer --outputdir .\n</pre>\n\nThis example\n- includes all types in the top-level namespace `Your.Models`\n- while excluding\n  - nested types called `Metadata` and\n  - types ending in `Map` in descendant `.Data.` namespaces.\n\n#### Strip namespaces from XML comments\n\nYou can reduce the noise in the XML documentation comments on classes on your diagrams by supplying a space-separated list of namespaces to omit from the output like so:\n\n<pre>\nilspycmd.exe <b>--generate-diagrammer-strip-namespaces System.Collections.Generic System</b> ..\\path\\to\\your\\assembly.dll --generate-diagrammer --output-folder .\n</pre>\n\nNote how `System` is replaced **after** other namespaces starting with `System.` to achieve complete removal.\nOtherwise `System.Collections.Generic` wouldn't match the `Collections.Generic` left over after removing `System.`, resulting in partial removal only.\n\n#### Adjust for custom XML documentation file names\n\nIf - for whatever reason - you have customized your XML documentation file output name, you can specify a custom path to pick it up from.\n\n<pre>\nilspycmd.exe <b>--generate-diagrammer-docs ..\\path\\to\\your\\docs.xml</b> ..\\path\\to\\your\\assembly.dll --generate-diagrammer --output-folder .\n</pre>\n"

The generation and parsing of the \n    various data types are done through the TypeConverter classes \n    associated with the data types.\n    \n    Example:\n    \n    ... ado.net/XML headers & schema ...\n    <resheader name=\"resmimetype\">text/microsoft-resx</resheader>\n    <resheader name=\"version\">2.0</resheader>\n    <resheader name=\"reader\">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>\n    <resheader name=\"writer\">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>\n    <data name=\"Name1\"><value>this is my long string</value><comment>this is a comment</comment></data>\n    <data name=\"Color1\" type=\"System.Drawing.Color, System.Drawing\">Blue</data>\n    <data name=\"Bitmap1\" mimetype=\"application/x-microsoft.net.object.binary.base64\">\n        <value>[base64 mime encoded serialized .NET Framework object]</value>\n    </data>\n    <data name=\"Icon1\" type=\"System.Drawing.Icon, System.Drawing\" mimetype=\"application/x-microsoft.net.object.bytearray.base64\">\n        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>\n        <comment>This is a comment</comment>\n    </data>\n                \n    There are any number of \"resheader\" rows that contain simple \n    name/value pairs.\n    \n    Each data row contains a name, and value. The row also contains a \n    type or mimetype. Type corresponds to a .NET class that support \n    text/value conversion through the TypeConverter architecture. \n    Classes that don't support this are serialized and stored with the \n    mimetype set.\n    \n    The mimetype is used for serialized objects, and tells the \n    ResXResourceReader how to depersist the object. This is currently not \n    extensible. For a given mimetype the value must be set accordingly:\n    \n    Note - application/x-microsoft.net.object.binary.base64 is the format \n    that the ResXResourceWriter will generate, however the reader can \n    read any of the formats listed below.\n    \n    mimetype: application/x-microsoft.net.object.binary.base64\n    value   : The object must be serialized with \n            :

You can change this by toggling the setting at Options &gt; Decompiler &gt; Project export &gt; Use nested directories for namespaces.

For a given mimetype the value must be set accordingly:\n    \n    Note - application/x-microsoft.net.object.binary.base64 is the format \n    that the ResXResourceWriter will generate, however the reader can \n    read any of the formats listed below.\n    \n    mimetype: application/x-microsoft.net.object.binary.base64\n    value   : The object must be serialized with \n            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter\n            : and then encoded with base64 encoding.\n    \n    mimetype: application/x-microsoft.net.object.soap.base64\n    value   : The object must be serialized with \n            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter\n            : and then encoded with base64 encoding.\n\n    mimetype: application/x-microsoft.net.object.bytearray.base64\n    value   : The object must be serialized into a byte array \n            : using a System.ComponentModel.TypeConverter\n            : and then encoded with base64 encoding.\n    -->\n  <xsd:schema id=\"root\" xmlns=\"\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:msdata=\"urn:schemas-microsoft-com:xml-msdata\">\n    <xsd:import namespace=\"http://www.w3.org/XML/1998/namespace\" />\n    <xsd:element name=\"root\" msdata:IsDataSet=\"true\">\n      <xsd:complexType>\n        <xsd:choice maxOccurs=\"unbounded\">\n          <xsd:element name=\"metadata\">\n            <xsd:complexType>\n              <xsd:sequence>\n                <xsd:element name=\"value\" type=\"xsd:string\" minOccurs=\"0\" />\n              </xsd:sequence>\n              <xsd:attribute name=\"name\" use=\"required\" type=\"xsd:string\" />\n              <xsd:attribute name=\"type\" type=\"xsd:string\" />\n              <xsd:attribute name=\"mimetype\" type=\"xsd:string\" />\n              <xsd:attribute ref=\"xml:space\" />\n            </xsd:complexType>\n          </xsd:element>\n          <xsd:element name=\"assembly\">\n            <xsd:complexType>\n              <xsd:attribute name=\"alias\" type=\"xsd:string\" />\n              <xsd:attribute name=\"name\" type=\"xsd:string\" />\n            </xsd:complexType>\n          </xsd:element>\n          <xsd:element name=\"data\">\n            <xsd:complexType>\n              <xsd:sequence>\n                <xsd:element name=\"value\" type=\"xsd:string\" minOccurs=\"0\" msdata:Ordinal=\"1\" />\n                <xsd:element name=\"comment\" type=\"xsd:string\" minOccurs=\"0\" msdata:Ordinal=\"2\" />\n              </xsd:sequence>\n              <xsd:attribute name=\"name\" type=\"xsd:string\" use=\"required\" msdata:Ordinal=\"1\" />\n              <xsd:attribute name=\"type\" type=\"xsd:string\" msdata:Ordinal=\"3\" />\n              <xsd:attribute name=\"mimetype\" type=\"xsd:string\" msdata:Ordinal=\"4\" />\n              <xsd:attribute ref=\"xml:space\" />\n            </xsd:complexType>\n          </xsd:element>\n          <xsd:element name=\"resheader\">\n            <xsd:complexType>\n              <xsd:sequence>\n                <xsd:element name=\"value\" type=\"xsd:string\" minOccurs=\"0\" msdata:Ordinal=\"1\" />\n              </xsd:sequence>\n              <xsd:attribute name=\"name\" type=\"xsd:string\" use=\"required\" />\n            </xsd:complexType>\n          </xsd:element>\n        </xsd:choice>\n      </xsd:complexType>\n    </xsd:element>\n  </xsd:schema>\n  <resheader name=\"resmimetype\">\n    <value>text/microsoft-resx</value>\n  </resheader>\n  <resheader name=\"version\">\n    <value>2.0</value>\n  </resheader>\n  <resheader name=\"reader\">\n    <value>System.Resources.ResXResourceReader, System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</value>\n  </resheader>\n  <resheader name=\"writer\">\n    <value>System.Resources.ResXResourceWriter, System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</value>\n  </resheader>\n</root>"

The generation and parsing of the \n    various data types are done through the TypeConverter classes \n    associated with the data types.\n    \n    Example:\n    \n    ... ado.net/XML headers & schema ...\n    <resheader name=\"resmimetype\">text/microsoft-resx</resheader>\n    <resheader name=\"version\">2.0</resheader>\n    <resheader name=\"reader\">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>\n    <resheader name=\"writer\">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>\n    <data name=\"Name1\"><value>this is my long string</value><comment>this is a comment</comment></data>\n    <data name=\"Color1\" type=\"System.Drawing.Color, System.Drawing\">Blue</data>\n    <data name=\"Bitmap1\" mimetype=\"application/x-microsoft.net.object.binary.base64\">\n        <value>[base64 mime encoded serialized .NET Framework object]</value>\n    </data>\n    <data name=\"Icon1\" type=\"System.Drawing.Icon, System.Drawing\" mimetype=\"application/x-microsoft.net.object.bytearray.base64\">\n        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>\n        <comment>This is a comment</comment>\n    </data>\n                \n    There are any number of \"resheader\" rows that contain simple \n    name/value pairs.\n    \n    Each data row contains a name, and value. The row also contains a \n    type or mimetype. Type corresponds to a .NET class that support \n    text/value conversion through the TypeConverter architecture. \n    Classes that don't support this are serialized and stored with the \n    mimetype set.\n    \n    The mimetype is used for serialized objects, and tells the \n    ResXResourceReader how to depersist the object. This is currently not \n    extensible. For a given mimetype the value must be set accordingly:\n    \n    Note - application/x-microsoft.net.object.binary.base64 is the format \n    that the ResXResourceWriter will generate, however the reader can \n    read any of the formats listed below.\n    \n    mimetype: application/x-microsoft.net.object.binary.base64\n    value   : The object must be serialized with \n            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter\n            : and then encoded with base64 encoding.\n    \n    mimetype: application/x-microsoft.net.object.soap.base64\n    value   : The object must be serialized with \n            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter\n            : and then encoded with base64 encoding.\n\n    mimetype: application/x-microsoft.net.object.bytearray.base64\n    value   : The object must be serialized into a byte array \n            : using a System.ComponentModel.TypeConverter\n            : and then encoded with base64 encoding.\n    -->\n  <xsd:schema id=\"root\" xmlns=\"\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:msdata=\"urn:schemas-microsoft-com:xml-msdata\">\n    <xsd:import namespace=\"http://www.w3.org/XML/1998/namespace\" />\n    <xsd:element name=\"root\" msdata:IsDataSet=\"true\">\n      <xsd:complexType>\n        <xsd:choice maxOccurs=\"unbounded\">\n          <xsd:element name=\"metadata\">\n            <xsd:complexType>\n              <xsd:sequence>\n                <xsd:element name=\"value\" type=\"xsd:string\" minOccurs=\"0\" />\n              </xsd:sequence>\n              <xsd:attribute name=\"name\" use=\"required\" type=\"xsd:string\" />\n              <xsd:attribute name=\"type\" type=\"xsd:string\" />\n              <xsd:attribute name=\"mimetype\" type=\"xsd:string\" />\n              <xsd:attribute ref=\"xml:space\" />\n            </xsd:complexType>\n          </xsd:element>\n          <xsd:element name=\"assembly\">\n            <xsd:complexType>\n              <xsd:attribute name=\"alias\" type=\"xsd:string\" />\n              <xsd:attribute name=\"name\" type=\"xsd:string\" />\n            </xsd:complexType>\n          </xsd:element>\n          <xsd:element name=\"data\">\n            <xsd:complexType>\n              <xsd:sequence>\n                <xsd:element name=\"value\" type=\"xsd:string\" minOccurs=\"0\" msdata:Ordinal=\"1\" />\n                <xsd:element name=\"comment\" type=\"xsd:string\" minOccurs=\"0\" msdata:Ordinal=\"2\" />\n              </xsd:sequence>\n              <xsd:attribute name=\"name\" type=\"xsd:string\" use=\"required\" msdata:Ordinal=\"1\" />\n              <xsd:attribute name=\"type\" type=\"xsd:string\" msdata:Ordinal=\"3\" />\n              <xsd:attribute name=\"mimetype\" type=\"xsd:string\" msdata:Ordinal=\"4\" />\n              <xsd:attribute ref=\"xml:space\" />\n            </xsd:complexType>\n          </xsd:element>\n          <xsd:element name=\"resheader\">\n            <xsd:complexType>\n              <xsd:sequence>\n                <xsd:element name=\"value\" type=\"xsd:string\" minOccurs=\"0\" msdata:Ordinal=\"1\" />\n              </xsd:sequence>\n              <xsd:attribute name=\"name\" type=\"xsd:string\" use=\"required\" />\n            </xsd:complexType>\n          </xsd:element>\n        </xsd:choice>\n      </xsd:complexType>\n    </xsd:element>\n  </xsd:schema>\n  <resheader name=\"resmimetype\">\n    <value>text/microsoft-resx</value>\n  </resheader>\n  <resheader name=\"version\">\n    <value>2.0</value>\n  </resheader>\n  <resheader name=\"reader\">\n    <value>System.Resources.ResXResourceReader, System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</value>\n  </resheader>\n  <resheader name=\"writer\">\n    <value>System.Resources.ResXResourceWriter, System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089</value>\n  </resheader>\n  <assembly alias=\"System.Windows.Forms\" name=\"System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089\" />\n  <data name=\"Icon\" type=\"System.Resources.ResXFileRef, System.Windows.Forms\">\n    <value>Icon.ico;System.Drawing.Icon, System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a</value>\n  </data>\n</root>"

You need the following workload components:\n  - Workload \".NET Desktop Development\". This workload includes the .NET Framework 4.8 SDK and the .NET Framework 4.7.2 targeting pack, as well as the [.NET 10.0 SDK](https://dotnet.microsoft.com/download/dotnet/10.0) (ILSpy.csproj targets .NET 10.0, but we have net472 projects too).\n  - Workload \"Visual Studio extension development\" (Note: ILSpy.VSExtensions.sln is separate from ILSpy.sln and thus this workload is optional)\n  - Individual Component \"MSVC v143 - VS 2022 C++ x64/x86 build tools\" (or similar)\n    - _The VC++ toolset is optional_; if present it is used for `editbin.exe` to modify the stack size used by ILSpy.exe from 1MB to 16MB, because the decompiler makes heavy use of recursion, where small stack sizes lead to problems in very complex methods.\n- Open ILSpy.sln in Visual Studio.\n  - NuGet package restore will automatically download further dependencies\n  - Run project \"ILSpy\" for the ILSpy UI\n  - Use the Visual Studio \"Test Explorer\" to see/run the tests\n  - If you are only interested in a specific subset of ILSpy, you can also use\n    - ILSpy.Wpf.slnf: for the ILSpy WPF frontend\n    - ILSpy.XPlat.slnf: for the cross-platform CLI or PowerShell cmdlets\n    - ILSpy.AddIn.slnf: for the Visual Studio plugin\n\n**Note:** Visual Studio includes a version of the .NET SDK that is managed by the Visual Studio installer - once you update, it may get upgraded too.\nPlease note that ILSpy is only compatible with the .NET 10.0 SDK and Visual Studio will refuse to load some projects in the solution (and unit tests will fail). \nIf this problem occurs, please manually install the .NET 10.0 SDK from [here](https://dotnet.microsoft.com/download/dotnet/10.0).\n\n#### Unix / Mac:\n\n- Make sure [.NET 10.0 SDK](https://dotnet.microsoft.com/download/dotnet/10.0) is installed.\n- Make sure [PowerShell](https://github.com/PowerShell/PowerShell) is installed (formerly known as PowerShell Core)\n- Clone the repository using git.\n- Execute `git submodule update --init --recursive` to download the ILSpy-Tests submodule (used by some test cases).\n- Use `dotnet build ILSpy.XPlat.slnf` to build the non-Windows flavors of ILSpy (.NET Core Global Tool and PowerShell Core).\n\nHow to contribute\n-----------------\n\n- Report bugs\n- If you want to contribute a pull request, please add https://github.com/icsharpcode/ILSpy/blob/master/BuildTools/pre-commit to your `.git/hooks` to prevent checking in code with wrong formatting. We use tabs and not spaces. The build server runs the same script, so any pull requests using wrong formatting will fail.\n\nCurrent and past [contributors](https://github.com/icsharpcode/ILSpy/graphs/contributors).\n\nPrivacy Policy for ILSpy\n------------------------\n\nILSpy does not collect any personally identifiable information, nor does it send user files to 3rd party services. \nILSpy does not use any APM (Application Performance Management) service to collect telemetry or metrics.\n"

Here every nested pattern must be a pattern according to `IsPattern()`, and the `testedOperand` of each must be a member of the `Variable` of the parent pattern. (members are: field, property, or deconstruction.result).\n(exception: `match.and`/`match.or`, these instead require the `testedOperand` to be exactly the `Variable` of the parent pattern)\n\n\nExamples\n--------\n1) `expr is var x`\n    =>\n    `match.var(x = expr)`\n    =>\n    ```\n    Block (VarPattern) {\n\t    stloc x(expr)\t\t// single eval expr\n\t    final: ldc.i4 1\t\t// match always\n    }\n    ```\n2) `expr is T x`\n\t=>\n    `match.type T(x = expr) {}`\n    =>\n\t```\n    Block (TypePattern) {\n        stloc x(isinst T(expr))\n        final: x != null\n    }\n\t```\n3) `expr is C { A: var x } z`\n\t=>\n    ```\n    match.type C(z = expr) {\n       match.var(x = z.A)\n    }\n    ```\n    =>\n\t```\n    Block (TypePattern) {\n        stloc z(isinst T(expr))\n        final: (z != null)\n            && Block(VarPattern) {\n                 stloc x(z.A)\n                 final: ldc.i4 1\n               }\n    }\n\t```\n4) `expr is C { A: var x, B: 42, C: { A: 4 } } z`\n    =>\n    ```\n    match.type C(z = expr) {\n        match.var (x = z.A),\n        comp (z.B == 42),\n        match.recursive (temp2 = z.C) {\n            comp (temp2.A == 4)\n        }\n    }\n    ```\n\t=>\n\t```\n    Block (TypePattern) {\n        stloc z(isinst C(expr))\n        final: (z != null)\n            && Block(VarPattern) {\n                 stloc x(z.A)\n                 final: ldc.i4 1\n               }\n            && comp (z.B == 42)\n            && Block(RecursivePattern) {\n                 stloc temp2(z.C)\n                 final: (temp2 != null)\n                     && comp (temp2.A == 4)\n               }\n    }\n\t```\n5) `expr is C(var x, var y, <4) { ... }`\n   =>\n   ```\n   match.recursive.type.deconstruct(C tmp1 = expr) {\n       match.var(x = deconstruct.result0(tmp1)),\n       match.var(y = deconstruct.result1(tmp1)),\n       comp(deconstruct.result2(tmp1) < 4),\n   }\n   ```\n\n6) `expr is C(1, D(2, 3))`\n    =>\n    ```\n    match.type.deconstruct(C c = expr) {\n        comp(deconstruct.result0(c) == 1),\n        match.type.deconstruct(D d = deconstruct.result1(c)) {\n            comp(deconstruct.result0(d) == 2),\n            comp(deconstruct.result1(d) == 2),\n        }\n    }\n    ```\n    \n7) `x is >= 0 and var y and <= 100`\n    ```\n    match.and(tmp1 = x) {\n        comp(tmp1 >= 0),\n        match.var(y = tmp1),\n        comp(tmp1 <= 100)\n    }\n    ```\n\n8) `x is not C _`\n    =>\n    ```\n    logic.not(\n        match.type(C tmp1 = x) {}\n    )\n    ```\n\n9) `expr is (var a, var b)` (when expr is object)\n    =>\n    ```\n    match.type.deconstruct(ITuple tmp = expr) {\n        match.var(a = deconstruct.result0(tmp)),\n        match.var(b = deconstruct.result1(tmp)),\n    }\n    ```\n    \n10) `expr is (var a, var b)` (when expr is ValueTuple<int, int>)\n    =>\n    ```\n    match.recursive(tmp = expr) {\n        match.var(a = tmp.Item1),\n        match.var(b = tmp.Item2),\n    }\n    ```"

While redistributing\n    the Work or Derivative Works thereof, You may choose to offer,\n    and charge a fee for, acceptance of support, warranty, indemnity,\n    or other liability obligations and/or rights consistent with this\n    License. However, in accepting such obligations, You may act only\n    on Your own behalf and on Your sole responsibility, not on behalf\n    of any other Contributor, and only if You agree to indemnify,\n    defend, and hold each Contributor harmless for any liability\n    incurred by, or claims asserted against, such Contributor by reason\n    of your accepting any such warranty or additional liability.\n\nEND OF TERMS AND CONDITIONS\n\n\nLicense Notice for Data Grid Extensions (part of ILSpy)\n---------------------------\n\nhttps://github.com/dotnet/DataGridExtensions/blob/master/License\n\nThe MIT License (MIT)\nCopyright (c) .NET Foundation and Contributors\nAll Rights Reserved\n\nPermission is hereby granted, free of charge, to any person obtaining a copy \nof this software and associated documentation files (the \"Software\"), to deal \nin the Software without restriction, including without limitation the rights \nto use, copy, modify, merge, publish, distribute, sublicense, and/or sell \ncopies of the Software, and to permit persons to whom the Software is \nfurnished to do so, subject to the following conditions:\n\nThe above copyright notice and this permission notice shall be included \nin all copies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED \"AS IS\", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR \nIMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, \nFITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
