Hi JB, I find its resolution. First, I create a variable, like:
1. var temp = new VariableDefinition(MethodModule.Import(typeof(object
)));
2. var tempctorref = MethodModule.Import(typeof(object
).GetConstructor(new Type[]{}));
3. method.Body.Variables.Add(temp);
then,just use :
1. ins = ilProcessor.Create(OpCodes.Stloc, temp);
so, I don't care about what's the index of the call stack. Is it right?
