How do I decompile a .NET EXE into readable C# source code?
提问by MusiGenesis
I wrote a C# application for a client a couple of years ago, but I no longer have the source code. All I have is the EXE that I deployed on the client's PC. Is there a way I can generate C# source code from the EXE?
几年前我为客户编写了一个 C# 应用程序，但我不再拥有源代码。我所拥有的只是我在客户端 PC 上部署的 EXE。有没有办法从 EXE 生成 C# 源代码？

Reflectorand its add-in FileDisassembler.
Reflector及其插件FileDisassembler。
Reflector will allow to see the source code. FileDisassembler will allow you to convert it into a VS solution.
反射器将允许查看源代码。FileDisassembler 将允许您将其转换为 VS 解决方案。

Reflector and the File Disassembleradd-in from Denis Bauer. It actually produces source projects from assemblies, where Reflector on its own only displays the disassembled source.
Reflector 和来自 Denis Bauer的File Disassembler插件。它实际上从程序集生成源项目，其中 Reflector 本身仅显示反汇编的源。
ADDED: My latest favourite is JetBrains' dotPeek.

Reflector is no longer free in general, but they do offer it for free to open source developers: http://reflectorblog.red-gate.com/2013/07/open-source/
Reflector 通常不再免费，但他们确实向开源开发人员免费提供：http: //reflectorblog.red-gate.com/2013/07/open-source/
But a few companies like DevExtras and JetBrains have created free alternatives:
但是像 DevExtras 和 JetBrains 这样的一些公司已经创建了免费的替代品：

When Red Gate said there would no longer be a free version of .Net Reflector, I started using ILSpyand Telerik's JustDecompile. I have found ILSpy to decompile more accurately than JustDecompile (which is still in Beta). Red Gate has changed their decision and still have a free version of .Net Reflector, but now I like ILSpy.
当 Red Gate 说不再有免费版本的 .Net Reflector 时，我开始使用ILSpy和 Telerik 的JustDecompile。我发现 ILSpy 比 JustDecompile（仍处于 Beta 版）更准确地反编译。Red Gate 改变了他们的决定，仍然有一个免费版本的 .Net Reflector，但现在我喜欢 ILSpy。
From the ILSpy website (https://github.com/icsharpcode/ILSpy/):

I'm surprised no one has mentioned Microsoft's ildasm. It may not be as pretty as ILSpy or Reflector, but it comes with Visual Studio so many developers already have it.
我很惊讶没有人提到微软的ildasm。它可能不如 ILSpy 或 Reflector 漂亮，但它随 Visual Studio 一起提供，因此许多开发人员已经拥有它。
To run it (assuming VS 2013, should be similar for other versions):
运行它（假设 VS 2013，其他版本应该类似）：
- Select Start > All Programs > Visual Studio 2013 > Visual Studio Tools.
- Double-click on Developer Command Prompt for VS2013.
- Run "ildasm" from the resulting command prompt.
- In the tool, select File > Open and open your executable or DLL.
- 选择开始 > 所有程序 > Visual Studio 2013 > Visual Studio 工具。
- 双击 VS2013 的开发人员命令提示符。
- 从结果命令提示符运行“ildasm”。
- 在该工具中，选择文件 > 打开并打开您的可执行文件或 DLL。
Now you can navigate the DLL structure. Double-click on class members to see the IL. Use File > Dump to export IL to a file.
现在您可以浏览 DLL 结构。双击班级成员以查看 IL。使用 File > Dump 将 IL 导出到文件。
