如何查看 C# 编译器生成的 MSIL/CIL?为什么叫汇编? [英] How can I view MSIL / CIL generated by C# compiler? Why is it called assembly?

问题描述

我是 .NET C# 编程的新手.我正在关注几本书.据说不是将 C# 代码直接编译为机器代码，而是将其转换为中间语言(称为 MSIL 又名 CIL).但是当我编译时，我得到了一个 exe/dll 文件.

I'm new to .NET C# programming. I'm following few books. It is said that instead of compiling C# code directly to machine code, it is converted into an intermediate language (called MSIL aka CIL). But when I compile, I get an exe/dll file.

1. 这些 exe/dll 文件中是否包含此 MSIL/CIL?
2. 我想看看那个中间语言代码，只是为了感受一下它的存在.如何查看?
3. 他们将这个 exe/dll 文件称为 assembly.他们是否在使用这个花哨的词"?只是为了将它们与包含本机/机器代码的 exe/dll 文件区分开来?

1. Is this MSIL/CIL contained in these exe/dll files?
2. I want to see that intermediate language code, just to get feel for its existence. How do I view it?
3. They are calling this exe/dll file an assembly. Are they using this "fancy word" just to differentiate these from the exe/dll files that contain native/machine code?

推荐答案

1. 是的，更确切地说是在 PE 的 .text 部分文件(便携式可执行文件 = *.exe 或 *.dll).可以在此处找到更多信息.
2. 最好的选择是使用 ILSpy(Reflector 不再免费).它是一个免费的反汇编程序，可以将您的程序集反汇编为 MSIL 以及 C#、VB(在某种程度上)..NET Framework SDK 包含 ILDasm，它是官方的 MSIL 反汇编程序.
3. 基本上是的.程序集是包含 MSIL 代码和相应元数据的文件.这不仅限于 PE 文件本身，而是所有当前的 CLR 实现都使用它们.

1. Yes it is, more exactly in the .text section of the PE file (portable executable = *.exe or *.dll). More information can be found here.
2. The best choice is to use ILSpy (Reflector is no longer free). It's a free disassembler that can dissassemble your assembly into MSIL but also C#, VB (to some extent). The .NET Framework SDK contains ILDasm, which is the official MSIL dissasembler.
3. Basically yes. An assembly is a file that contains MSIL code and corresponding metadata. This is not restricted to PE files per se, but all current CLR implementations use them.

如果我也可以推荐一本关于这方面的好书，那就是 Serge Lidin 的 Expert .NET 2.0 IL Assembler.他是设计 MSIL 的人.

If I may recommend a good book on that matter too, it's Expert .NET 2.0 IL Assembler by Serge Lidin. He's the guy who designed MSIL.
