桥接模式

问题描述

对于不同系统的手机，软件基本无法兼容，因此如果手机需要增加软件，就需要针对不同品牌的手机分别实现软件功能。

代码实现

手机软件抽象类

    public abstract class HandsetSoft
    {
        public abstract void Run();
    }

手机软件具体实现类

public class HandsetGame : HandsetSoft
{
    public override void Run()
    {
        Console.WriteLine("运行手机游戏");
    }
}

public class HandsetAddressList : HandsetSoft
{
    public override void Run()
    {
        Console.WriteLine("运行手机通讯录");
    }
}

手机抽象类

    public abstract class HandsetBrand
    {
        protected HandsetSoft soft;
        public void SetHandsetSoft(HandsetSoft soft)
        {
            this.soft = soft;
        }
        public abstract void Run();
    }

手机具体实现类

    public class  HandsetBrandXiaomi : HandsetBrand
    {
        public override void Run()
        {
            soft.Run();
        }
    }

    public class HandsetBrandIPhone : HandsetBrand
    {
        public override void Run()
        {
            soft.Run();
        }
    }

Main方法调用

    internal class Program
    {
        static void Main(string[] args)
        {
            HandsetBrand brandMi = new HandsetBrandXiaomi();
            brandMi.SetHandsetSoft(new HandsetGame());
            brandMi.Run();

            brandMi.SetHandsetSoft(new HandsetAddressList());
            brandMi.Run();


            HandsetBrand brandIphone = new HandsetBrandIPhone();
            brandIphone.SetHandsetSoft(new HandsetGame());
            brandIphone.Run();

            brandIphone.SetHandsetSoft(new HandsetAddressList());
            brandIphone.Run();

        }
    }
