解决多集成，多子类，扩展等 ---装饰模式

    public abstract class Tank

    {

        public abstract void Shot();

        public abstract void Run();

    }

解决主题类再多种方向上的扩展功能

 

public abstract class Decorator:Tank

    {

        private Tank tank;



        public Decorator(Tank tank)

        {

            this.tank = tank;

        }



        public override void Shot()

        {

            Console.WriteLine( "Tank.Shot" );

            tank.Shot();

        }



        public override void Run()

        {

            Console.WriteLine( "Tank.Run" );

            tank.Run();

        }

    }

public class DecoratorA:Decorator

    {

        public DecoratorA( Tank tank )

            : base( tank )

        {

        }



        public override void Shot()

        {

            //Do some extension 红外线

            Console.WriteLine( "DecoratorA.Shot" );

            base.Shot();

        }



        public override void Run()

        {

            //Do Some extension

            Console.WriteLine( "DecoratorA.Run" );

            base.Run();

        }

    }



    public class DecoratorB : Decorator

    {

        public DecoratorB( Tank tank )

            : base( tank )

        {

        }



        public override void Shot()

        {

            //Do some extension 夜视功能

            Console.WriteLine( "DecoratorB.Shot" );

            base.Shot();

        }



        public override void Run()

        {

            //Do Some extension 夜视功能

            Console.WriteLine( "DecoratorB.Run" );

            base.Run();

        }

    }

他并不是is a关系，只是把当成接口，主题是has a关系

看调用

class Program

    {

        static void Main( string[] args )

        {

            Tank tank = new T50();

            DecoratorA da = new DecoratorA( tank );

            DecoratorB db = new DecoratorB( da );



            db.Shot();

        }

    }

  public class T50:Tank

    {

        public override void Shot()

        {

            Console.WriteLine( "T50.Shot" );

        }



        public override void Run()

        {

            Console.WriteLine( "T50.Run" );

        }

    }
