我如何定位模块?

How can I target a module?

我在参考程序集中搜索了一下,发现一个奇怪的东西 comment/snippet:

// Attribute class used by the compiler to mark modules.
// If present, then debugging information for everything in the 
// assembly was generated by the compiler, and will be preserved
// by the Runtime so that the debugger can provide full functionality
// in the case of JIT attach. If not present, then the compiler may
// or may not have included debugging information, and the Runtime 
// won't preserve the debugging info, which will make debugging after
// a JIT attach difficult. 
[AttributeUsage(AttributeTargets.Assembly|AttributeTargets.Module, AllowMultiple = false)] 
[ComVisible(true)]
public sealed class DebuggableAttribute : Attribute 
{

现在我跳上 AttributeTargets 并想知道 C#/.NET 中的模块是什么。

  [Flags]
  [ComVisible(true)]
  [__DynamicallyInvokable]
  [Serializable]
  public enum AttributeTargets
  {
    [__DynamicallyInvokable] Assembly = 1,
    [__DynamicallyInvokable] Module = 2,
    [__DynamicallyInvokable] Class = 4,
    [__DynamicallyInvokable] Struct = 8,
    [__DynamicallyInvokable] Enum = 16,
    [__DynamicallyInvokable] Constructor = 32,
    [__DynamicallyInvokable] Method = 64,
    [__DynamicallyInvokable] Property = 128,
    [__DynamicallyInvokable] Field = 256,
    [__DynamicallyInvokable] Event = 512,
    [__DynamicallyInvokable] Interface = 1024,
    [__DynamicallyInvokable] Parameter = 2048,
    [__DynamicallyInvokable] Delegate = 4096,
    [__DynamicallyInvokable] ReturnValue = 8192,
    [__DynamicallyInvokable] GenericParameter = 16384,
    [__DynamicallyInvokable] All = GenericParameter | ReturnValue | Delegate | Parameter | Interface | Event | Field | Property | Method | Constructor | Enum | Struct | Class | Module | Assembly,
  }

所以我的问题是 - 我怎样才能从 C# 代码中定位一个带有属性的模块?

使用 module 限定符,例如:

[module: Debuggable(DebuggableAttribute.DebuggingModes.Default)]

可以放在任何 .cs 文件中任何 namespace/class 声明之上。

模块是类型的容器。大多数编译器(包括 C#)为每个程序集生成一个模块。可以在ILSpy等反汇编工具中查看模块级属性

请注意,这与 VB.NET 模块不同,后者类似于 C# 静态 class。
