Need a method to get the non-generic signature of a MethodSpec

[Misaka-Mikoto-Tech]

I want to generate a Method with exactly the same ParameterDef and return type as MethodSpec, but the parameters obtained through methodSpec.GetParams() has generic type, such as T, U, how can I get its real type?

Access the GenericInstMethodSig property of MethodSpec. It contains the instantiation of the generic parameters (in order the same as generic method arguments). If you want to create an instantiated type, you must traverse the TypeSig structure until you find a GenericMVar and substitute it with the signature from the list. An example implementation of this can be found in ConfuserEx, see https://github.com/mkaring/ConfuserEx/blob/master/Confuser.Renamer/GenericArgumentResolver.cs

I made a slight modification and used it in my own project. Thank you very much for providing the solution, it helped me a lot!
