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
    }
    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();
          }
      }
