IL Call with Method from string

I've been trying to create my own toy programming language for CIL using IL Reflection to generate the exes, but when Im calling a method I just doesn't seem to work.

I am using System.Reflection.ILGenerator.Emit(OpCodes.Call, MethodInfo).

When getting the MethodInfo from a Type gotten by using the typeof(something), it works fine, the call is sent through and it works, but when I get the Type with the Type.GetType(string) function, for some reason it won't generate the IL, I have tested and found that the typeof == Type.GetType (there is no difference in the result when checking with the == operator).

I have looked around but can't seem to find any solution, can anyone tell me what's happening?

EDIT: here is a link to the git repo file

Code: 

//Create IL Generator and standard stuff before this...
ilGenerator.Emit(OpCodes.Ldstr, "hello world"); //Push argument(s)
MethodInfo method = typeof(Console).GetMethod("WriteLine", new Type[] { typeof(string) });
MethodInfo rmethod = Type.GetType("System.Console").GetMethod("WriteLine", new Type[] { typeof(string) });
if(method == rmethod)
{
    Console.WriteLine("MATCH!"); //This fires so I know they match
}
ilGenerator.Emit(OpCodes.Call, method); //This works
ilGenerator.Emit(OpCodes.Call, rmethod); //This does not... (no exceptions, but no code is generated looking with ILSpy afterwards)

I found the problem, at some point in my code before this was executed, the typebuilder.CreateType was fired, and this stoppes the il generation...

Thanks for the help though!
