Converting IL to C# code

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() which returns a byte array now I want to convert this IL to C# code. Please help me out in solving this.

The Lutz Roeder reflector was purchased and is no longer available for free download.

There is now a free (once again) tool called ILSpy. I've found it to be very good, and it will not only generate C# code from IL but will also create a .csproj project if decompiling an entire DLL assembly.

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).

For the search engine people, Reflector ain't free anymore. But a newer and better and not to mention FREE tool is being offered from telerik called JustDecompile. I just downloaded this and its so awesome and its just beta. Apparently telerik promises free forever.

Re-Inventing the wheel surely a better way to learn! you will have to create your own class that would convert iL to C#.This requires the knowledge of Intermediate language.

I assume you have already converted the Byte Array to IL instructions just like we see in ildasm.exe,Using Reflection.Emit.OpCodes,OpCode.OperandType,BitConvertor.ReadByte(),BitConvertor.ReadInt32 etc.

Maybe you should try Dis# if you don't wanna re-invent the wheel... It's almost the best tool in converting the code NetDASM has a tool that lets you convert C# to IL. maybe you should take a look at that.

Let me be the first to suggest you grab a copy of Red Gate's Reflector.

Reflector does this. Perhaps you could use Reflector against Reflector and learn how it handles the problem.

You might also say why you want to do this - there may be a better solution to your overall problem.

There is no tool in the BCL that will do this; however, there is a great tool called Reflector, which you can write your own add-ins for. So you could probally use this to get the data you want.
