Convert C# code to IL code

Question

How I can get IL code of C# code ? Can I do this with a extern library, or exists internal functions ?

EDIT : I want to show IL code in my application with a MessageBox.

Answer 1

Programmatically? You can use reflection to get a MethodInfo, and then call MethodBase.GetMethodBody to get the body. From the MethodBody, you can call GetILAsByteArray amongst other things.

Of course, if you just want to examine it yourself, there's Reflector, dotPeek, ildasm (part of the .NET SDK) and no doubt other tools...

Answer 2

Use IL Disassembler like this:

c:\il>csc Class.cs    
c:\il>ildasm /output=Class.il Class.exe

you'll both have the IL & the exe.
