编辑 .NET 程序集并重新编译

Edit .NET assembly and recompile

提问by Bac Clunky

I'm in a really bad situation. I lost my source code and my customer needs to change a little bit in the application. Think of edit an assembly for an example: Test.dll then add a code line and finally recompile it

我的处境非常糟糕。我丢失了源代码，我的客户需要对应用程序进行一些更改。以编辑程序集为例：Test.dll 然后添加一行代码，最后重新编译

So my question is: - Is it possible to do that? - If it's possible, what is the good tool to edit an assembly and then recompile it?

所以我的问题是： - 有可能这样做吗？- 如果可能的话，编辑程序集然后重新编译它的好工具是什么？

Yes, get ILSpy, it has the ability to save an assembly to disk with a .csproj and everything. This makes it easy to open in Visual Studio and recompile.

是的，获得ILSpy，它能够使用 .csproj 和所有内容将程序集保存到磁盘。这使得在 Visual Studio 中打开和重新编译变得容易。

ILSpy is free and open source.

ILSpy 是免费和开源的。

Exporting & recompiling might not be possible for large applications with many assembies, so I'd suggest a different approach:

对于具有许多程序集的大型应用程序，可能无法导出和重新编译，因此我建议采用不同的方法：

The most comfortable way to go might be to use Reflexilin combination with .NET Reflector(not free) or JustDecompile from Telerik(very free). I did this a few times and had the best result with JustDecompile - even if I'd prefer ILSpyover JustDecompile at any other time.

最舒适的方法可能是将Reflexil与.NET Reflector（非免费）或Telerik 的 JustDecompile（非常免费）结合使用。我这样做了几次，并且使用 JustDecompile 获得了最好的结果——即使我在其他任何时候都更喜欢ILSpy 而不是 JustDecompile。

"Now, how"? you might ask:Here's a small tutorial from the guys at Telerik.

“现在怎么办”？您可能会问：这是 Telerik 人员的一个小教程。

(look at the topic "How can I inject C# code in an assembly?")
