C#宠物医院案例步骤演练

- 创建子类
小猪类

class pig:TrafficTool
    {
        public override void run()
        {
            Console.WriteLine("输液");
        }
    }

小猫类

class cat:TrafficTool
    {
        public override void run()
        {
            Console.WriteLine("打针");
        }
    }

小狗类

class dog:TrafficTool
    {
        public override void run()
        {
            Console.WriteLine("吃药");
        }
    }

创建方法类

class Employee
    {
        public void GoHome(TrafficTool t, SE s) {
            Console.WriteLine("为"+s.Name+"看病");
            t.run();
        }
    }

创建父类

class TrafficTool
    {
        public virtual void run()
        {
            Console.WriteLine("看病");
        }
    }

创建数据存放处SE

class SE
    {
        private String id;

        public String Id {
            get { return id; }
            set { id = value;}
        }

        private String name;

        public String Name {
            get { return name;}
            set { name = value;}
        }

        private int age;

        public int Age {
            get { return age; }
            set { age = value; }
        }

        public SE(string id, string name, int age) {
            this.Id = id;
            this.Name = name;
            this.Age = age;
        }
    }

程序入口类

static void Main(string[] args)
        {
            SE s = new SE("111","小狗",25);
            SE s1 = new SE("111", "小猫", 25);
            SE s2 = new SE("111", "小猪", 25);

            TrafficTool c = new dog();
            TrafficTool c1 = new cat();
            TrafficTool c2 = new pig();

            Employee e = new Employee();
            e.GoHome(c,s);
            Employee e1 = new Employee();
            e.GoHome(c1, s1);
            Employee e2 = new Employee();
            e.GoHome(c2, s2);

            Console.ReadKey();
        }
