面向接口编程之惑 第二版

刚才对面向接口充满了疑惑 经过自己的仔细推敲 加上 Vs 的智能提示 终于找到解决方法了 放代码出来啊 如果你刚看过那篇 你应该很清楚了啊

 

 class Program
    {
        static void Main(string[] args)
        {
            Computeruse com = new Computeruse();
            Adult me = new Adult();
            me.UseComputer(com);
            Child mybrother = new Child();
            mybrother.UseComputer(com);
            Console.ReadLine();
        }
    }
    class Computeruse : IFinal
    {
        public Computeruse()
        {
            Console.WriteLine("这个电脑我在用 别管我干嘛!!");
        }
        IFinal 成员#region IFinal 成员

        public void ToLearn()
        {
            Console.WriteLine("我用电脑学习!");
        }

        public void ToWork()
        {
            Console.WriteLine("我用电脑工作!");
        }

        public void ToFun()
        {
            Console.WriteLine("我用玩游戏!");
        }

        #endregion
    }
    interface IFinal
    {
        void ToLearn();
        void ToWork();
        void ToFun();
    }
    interface IComputerLearn:IFinal
    {
        void ToLearn();
    }
    interface IComputerWork:IFinal
    {
        void ToWork();
    }
    interface IComputerToFun:IFinal
    {
        void ToFun();
    }
    class Adult
    {
      public void UseComputer(IFinal IFinal)
      {
          IFinal.ToLearn();
          IFinal.ToFun();
      }
    }
      class Child
      {
          public void UseComputer( IFinal IFinal)
          {
              IFinal.ToFun();
          }
      }

这个应该是面向接口的最终版本了 希望下个项目会用到这个啊  呵呵~~
