c#之接口

给自己看的：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace 接口类演示
{
    class Program
    {
        static void Main(string[] args)
        {
            Ifun f = new myclass2();
            myclass2 my = f as myclass2;
            myclass1 my1 = my as myclass1;
            bool b=object.ReferenceEquals(f,my);
            Console.WriteLine(object.ReferenceEquals(my,my1));
            Console.WriteLine(b);
            Console.ReadLine();
        }
    }
    public interface Ifun
    {
        void method();
    }
    class myclass1 : Ifun
    {


        public void method()
        {
            Console.WriteLine("在类中实现了Ifun接口");
        }
    }
    class myclass2 : myclass1
    { 
    
    }
