面向接口编程（Adapter）

这几天不知道为什么 ，突然想琢磨接口技术，接触了接口才知道它的强大.

下面的这小段代码  这里引入一个设计模式，“Adapter”。它的作用就如现实中的适配器一样，把接口不一致的两个插件接合起来。其实很简单.

 

 

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

namespace InterfaceExample //接口果然强大!!.
{
    public interface IMobileStorage
    {
        void read();
        void write();

    }
    public class FlashDisk : IMobileStorage
    {
        public void read()
        {
            Console.WriteLine("这是U盘－－读取－－数据正常");
        }
        public void write()
        {
            Console.WriteLine("这是U盘－－写入－－数据正常");
        }
    }
    public class MP3Player : IMobileStorage
    {
        public void read()
        {
            Console.WriteLine("这是MP3－－读取－－数据正常");
        }
