[Mono-list] GetMethodFromHandle and NotImplementedException

[Gert Driesen]

Hi Carlos,
 
This was recently implemented, and is now working fine on Mono.

Sorry there was an error in the code before.
This is the right Main method (working on .Net):
 
public

static void Main(string [] args) 

{

Console.WriteLine("Hello World!"); 

TestClass<int> test = new TestClass<int>(); 

RuntimeMethodHandle methodHandle =
test.GetType().GetProperty("MyList").GetGetMethod().MethodHandle; 

MethodBase methodBase = MethodInfo.GetMethodFromHandle(methodHandle,
typeof(TestClass<int>).TypeHandle); 

List<int> list = (List< int>)methodBase.Invoke(test, null); 

Console.WriteLine(list.Count); 

}

Cheers

Hi, the sample bellow throwns the NotImplementedException:
 
using System;
using System.Reflection;
using System.Collections.Generic;

namespace test1
{
    public class TestClass<T>
    {
        private List<T> _myList = new List<T>(); 
        
        public List<T> MyList
        {
            get
            {
                return _myList;
            }
                
        }
    }
    
    class MainClass 
    {
        public static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");
            
            TestClass<int> test = new TestClass<int>();
            RuntimeMethodHandle methodHandle =
test.GetType().GetProperty("MyList").GetGetMethod().MethodHandle;
            RuntimeTypeHandle typeHandle = typeof(int).TypeHandle;
            MethodBase methodBase =
MethodInfo.GetMethodFromHandle(methodHandle, typeHandle);
            List<int> list = (List<int>)methodBase.Invoke(test, null);
            Console.WriteLine(list.Count);
        }
    }
}

Please post samples.
