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" );
            }
        }

在.net里面的装饰功能
