Question

Consider type like this one

public interface IHaveGenericMethod {    T1 Method<T1>(T1 parm);    T2 Method<T1,T2>(T1 parm);    int Method2(int parm); } 

How do I get a methodInfo for its methods? for a regular non-generic method, like method2, I can go with

typeof(IHaveGenericMethod).GetMethod('methodName',new Type[]{typeof(itsParameters)}); 

for a generic method though, I can’t, since it’s parameters are not types per-se. So, how do I do that? I know that I can call

typeof(IHaveGenericMethod).GetMethods() 

to get all methods of that type, and then iterate over that collection and do some matching, but it’s ugly. Is there a better way?

Well, they are types – of sorts:

    foreach (var method in typeof(IHaveGenericMethod).GetMethods())     {         Console.WriteLine(method.Name);         if (method.IsGenericMethodDefinition)         {             foreach (Type type in method.GetGenericArguments())             {                 Console.WriteLine('> ' + type.Name);             }         }     } 

So you can check by the number of args, and check the signature. But nothing cleaner.
