Late Binding Delegates: A delegate is a repository of type-safe function pointers.

 

using System;
using System.Reflection;

delegate void XDelegate(int arga, int argb);

class MyClass {
    public void MethodA(int arga, int argb) {
        Console.WriteLine("MyClass.MethodA called: {0} {1}", arga, argb);
    }
}

class Starter {
    static void Main() {
        MyClass obj = new MyClass();
        XDelegate delObj = new XDelegate(obj.MethodA);
        delObj.Invoke(1, 2);
        delObj(3, 4);
    }
}
