Understand implementation details of .NET code by decompiling assemblies. Use when you want to see how a .NET API works internally, inspect NuGet package source, view framework implementation, or understand compiled .NET binaries.

场景.net调试源码分析api探究

适合你，如果想查看 .NET 库或 NuGet 包的源代码

怎么用

商店整理自技能原文 · 版本 642e21e · 表述以原文为准
它做什么

装上后，Claude可以反编译.NET程序集（.dll文件），并把编译后的二进制代码还原成可读的C#源码，让你看到类、方法等内部实现。

什么时候触发

当你询问某个.NET API的内部工作原理、想查看NuGet包源码、框架实现或理解编译后的二进制代码时触发。

装好后可以这样说
Claude会使用 -l c 参数列出类名。

.NET Assembly Decompilation with ILSpy

Use this skill to understand how .NET code works internally by decompiling compiled assemblies.

Prerequisites
  • .NET SDK installed
  • ILSpy command-line tool available via one of the following:
  • dotnet dnx ilspycmd (if available in your SDK or runtime)
  • dotnet tool install --global ilspycmd

Both forms are shown below. Use the one that works in your environment.

Note: ILSpyCmd options may vary slightly by version. Always verify supported flags with ilspycmd -h.
Quick start
# Decompile an assembly to stdout
ilspycmd MyLibrary.dll
# or
dotnet dnx ilspycmd MyLibrary.dll

# Decompile to an output folder
ilspycmd -o output-folder MyLibrary.dll
Common .NET Assembly Locations
NuGet packages
~/.nuget/packages/<package-name>/<version>/lib/<tfm>/
.NET runtime libraries
dotnet --list-runtimes
.NET SDK reference assemblies
dotnet --list-sdks
Reference assemblies do not contain implementations.
Project build output
./bin/Debug/net8.0/<AssemblyName>.dll
./bin/Release/net8.0/publish/<AssemblyName>.dll
Core workflow
  1. Identify what you want to understand
  2. Locate the assembly
  3. List types to find the target
  4. Decompile the target
Commands
List types in an assembly

Use -l with an entity type to discover what's inside:

# List classes
ilspycmd -l c MyLibrary.dll

# List interfaces
ilspycmd -l i MyLibrary.dll

# List structs, delegates, enums
ilspycmd -l s MyLibrary.dll
ilspycmd -l d MyLibrary.dll
ilspycmd -l e MyLibrary.dll
Basic decompilation
ilspycmd MyLibrary.dll
ilspycmd -o ./decompiled MyLibrary.dll
ilspycmd -p -o ./project MyLibrary.dll
Targeted decompilation
# Decompile specific type
ilspycmd -t Namespace.ClassName MyLibrary.dll

# Specify C# language version (default: Latest)
ilspycmd -lv CSharp12_0 MyLibrary.dll
View IL code
ilspycmd -il MyLibrary.dll
Clean output
# Remove dead code and dead stores for cleaner results
ilspycmd --no-dead-code --no-dead-stores MyLibrary.dll
Organized project output
# Decompile with nested directories matching namespaces
ilspycmd --nested-directories -p -o ./decompiled MyLibrary.dll

Notes on modern .NET builds
  • ReadyToRun images may reduce readability
  • Trimmed or AOT builds may omit code
  • Prefer non-trimmed builds
