Thank you very much for your answer Daniel, I've tried what you posted
earlier, but when calling the "SimplifyMacros" method I get an
ArgumentOutOfRangeException. I know this might not be very helpful
information, so i'm posting the whole method i'm emitting here:
ilProc.Emit(OpCodes.Call,
asmDef.MainModule.Import(typeof(System.Reflection.Assembly).GetMethod("GetExecutingAssembly")));
ilProc.Emit(OpCodes.Ldstr, "str");
ilProc.Emit(OpCodes.Callvirt,
asmDef.MainModule.Import(typeof(System.Reflection.Assembly).GetMethod("GetManifestResourceStream",
new Type[]{ typeof(string) })));
ilProc.Emit(OpCodes.Stloc_0);
ilProc.Emit(OpCodes.Ldloc_0);
ilProc.Emit(OpCodes.Callvirt,
asmDef.MainModule.Import(typeof(Stream).GetMethod("get_Length")));
ilProc.Emit(OpCodes.Conv_Ovf_I);
ilProc.Emit(OpCodes.Newarr,
asmDef.MainModule.Import(typeof(Byte)));
ilProc.Emit(OpCodes.Stloc_1);
ilProc.Emit(OpCodes.Ldloc_0);
ilProc.Emit(OpCodes.Ldloc_1);
ilProc.Emit(OpCodes.Ldc_I4_0);
ilProc.Emit(OpCodes.Ldloc_1);
ilProc.Emit(OpCodes.Ldlen);
ilProc.Emit(OpCodes.Conv_I4);
ilProc.Emit(OpCodes.Callvirt,
asmDef.MainModule.Import(typeof(Stream).GetMethod("Read", new Type[]
{ typeof(byte[]), typeof(Int32), typeof(Int32)})));
ilProc.Emit(OpCodes.Pop);
ilProc.Emit(OpCodes.Call,
asmDef.MainModule.Import(typeof(Encoding).GetMethod("get_ASCII")));
ilProc.Emit(OpCodes.Ldloc_1);
ilProc.Emit(OpCodes.Callvirt,
asmDef.MainModule.Import(typeof(Encoding).GetMethod("GetString", new
Type[] { typeof(byte[]) })));
ilProc.Emit(OpCodes.Ldc_I4_1);
ilProc.Emit(OpCodes.Newarr,
asmDef.MainModule.Import(typeof(Char)));
ilProc.Emit(OpCodes.Stloc_2);
ilProc.Emit(OpCodes.Ldloc_2);
ilProc.Emit(OpCodes.Ldc_I4_0);
ilProc.Emit(OpCodes.Ldc_I4, 124);
ilProc.Emit(OpCodes.Stelem_I2);
ilProc.Emit(OpCodes.Ldloc_2);
ilProc.Emit(OpCodes.Callvirt,
asmDef.MainModule.Import(typeof(String).GetMethod("Split", new Type[]
{ typeof(char[]) })));
ilProc.Emit(OpCodes.Ldarg_1);
ilProc.Emit(OpCodes.Ldelem_Ref);
ilProc.Emit(OpCodes.Ret);
mDef.Body.SimplifyMacros();
