I need to convert the IL to c# code.
I have an assembly and I am reading this assembly.
I get MethodBody from MethodInfo and the methodbody has a method GetILAsByteArraY()
If you want to do it yourself, you could start from the old Cecil.Decompiler and enhance it, see the source code and an old post of Jb. Evain announcing the project (Link down).
