这里没有提到的其他一些-

Mono Cecil: With Cecil, you can load existing managed assemblies, browse all the contained types, modify them on the fly and save back to the disk the modified assembly. Kaliro: This is a tool for exploring the content of applications built using the Microsoft.Net framework. Dotnet IL Editor (DILE): Dotnet IL Editor (DILE) allows disassembling and debugging .NET 1.0/1.1/2.0/3.0/3.5 applications without source code or .pdb files. It can debug even itself or the assemblies of the .NET Framework on IL level. Common Compiler Infrastructure: Microsoft Research Common Compiler Infrastructure (CCI) is a set of libraries and an application programming interface (API) that supports some of the functionality that is common to compilers and related programming tools. CCI is used primarily by applications that create, modify or analyze .NET portable executable (PE) and debug (PDB) files.

我不知道你到底想要什么。如果你想看到。net框架的源代码，你可以试试Netmassdownloader。这是免费的。

如果你想看到任何程序集的代码(不仅仅是。net)，你可以使用ReSharper。虽然它不是免费的。

9Rays曾经有一个反编译器，但我有一段时间没有检查了。这不是免费的，我记得……

还有一个新的(至少对我来说)叫做Dis#。

. net源代码现已可用。

看这个链接或者这个

或者如果你想找一个反编译器，我用的是DisSharper。这对我来说已经足够好了。

Red Gate的最新版本是6.1。但是5.1版本不能自动更新到版本6，因为服务条款发生了变化，所以你会被重定向到网站下载6.1版本。这主要是因为法律原因，你可以在下面的帖子中查看:

Oi !.NET Reflector更新机制是怎么回事?

手动更新到6.1后，您将不再遇到任何问题。
