设计模式之适配器模式

　　　　适配器模式主要用于当我们写的代码与旧代码（可能不是我们写的）无法兼容时，做类型兼容，这样我们就可以轻松使用旧代码中的功能了，这个模式和装饰模式很像。

但二者还是有所区别的，装饰模式主要是为了为类添加装饰功能，将核心功能与装饰功能分开。适配器模式主要是为了新旧代码的兼容，万不得已才使用。

代码如下：

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

namespace 设计模式之适配器模式
{
    public abstract class Player
    {
        private string name;
        public string Name
        {
            get
            {
                return name;
            }
            set
            {
                name = value;
            }
        }
        abstract public void Go();
        abstract public void Defend();
    }
    public class AmericaPlayer : Player
    {
        public override void Go()
        {
            Console.WriteLine("{0} Let's Go!",Name);
        }
        public override void Defend()
        {
            Console.WriteLine("{0} Come back! Defend!",Name);
        }
    }
    public class ChinesePlayer 
    {
        private string name;
        public string Name
        {
            get
            {
                return name;
            }
            set
            {
                name = value;
            }
        }
        public void 进攻()
        {
            Console.WriteLine("{0} 进攻！",name);
        }
        public void 防守()
        {
            Console.WriteLine("{0} 回来防守！",name);
        }
    }
    public class BetweenPlayer : Player
    {
        public ChinesePlayer cPlayer = new ChinesePlayer();
        public override void Go()
        {
            cPlayer.进攻();
        }
        public override void Defend()
        {
            cPlayer.防守();
        }
    }
    class Program
    {
        static void Main(string[] args)
        {
            AmericaPlayer aPlayer = new AmericaPlayer();
            aPlayer.Name = "科比";
            aPlayer.Go();
            aPlayer.Defend();
            ChinesePlayer cPlayer = new ChinesePlayer();
            cPlayer.Name = "姚明";
            BetweenPlayer bPlayer = new BetweenPlayer();
            bPlayer.cPlayer = cPlayer;
            bPlayer.Go();
            bPlayer.Defend();
            Console.Read();

        }
    }
}

运行结果：
