model.File.InputStream.CopyTo(target);
byte[] data = target.ToArray();
It's easy enough to write the equivalent of CopyTo in .NET 3.5 if you want. The important part is that you read from HttpPostedFileBase.InputStream.

Get IL method content via MethodInfo.GetMethodBody().GetILAsByteArray()
Mess with these bytes.
If you just wish to prepend or append some code, then just preprend/append opcodes you want (be careful about leaving stack clean, though)
Here are some tips to "uncompile" existing IL:
