问题
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
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?
回答1:
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.
ILSpy is free and open source.

Exporting & recompiling might not be possible for large applications with many assembies, so I'd suggest a different approach:
The most comfortable way to go might be to use Reflexil in 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 ILSpy over JustDecompile at any other time.
"Now, how"? you might ask: Here's a small tutorial from the guys at Telerik.
(look at the topic "How can I inject C# code in an assembly?")
UPDATE
You should definitely look at the new kid on the block: dnSpy

Reflector is the most well known tool for disassembling .net Executables. Another tool is Dis#.
