C#学习之路，学习笔记 第九章 继承 9.2由基类创建派生类

 // 试一试：有Vertebral类派生Mammal类

<span style="font-size:14px;">using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace _9._2由基类创建派生类{    class Program    {        static void Main(string[] args)        {            Mammal beast = new Mammal();            Console.WriteLine("我是一只野兽");            Console.WriteLine("\n我有：");            Console.WriteLine(beast.Skins);            Console.WriteLine("\n我会：");            //下面从基类继承来的函数            beast.Breathe();            beast.Eat();            beast.Sleep();            //下面是派生类自己定义的函数            beast.Scukle();            beast.Run();            Console.ReadLine();        }    }    class Vertebrata    {        //私有成员        private double bodyWeight;        private double bodyTemperature;        //公有成员        //构造函数        public Vertebrata()        {            bodyTemperature = 0;            bodyWeight = 0;        }        //函数：呼吸        public void Breathe()        {            Console.WriteLine("呼吸");        }        //函数：进食        public void Eat()        {            Console.WriteLine("进食");        }        //函数：睡觉        public void Sleep()        {            Console.WriteLine("睡觉");        }    }    //下面，我们由Vertebrata类派生Mammal类    //哺乳动物类    class Mammal : Vertebrata    {        //私有成员        private string skins;    //毛皮        //公有成员        //构造函数        public Mammal()        {            skins = "毛皮";        }        //属性：Skins        public string Skins        {            get            {                return skins;            }            set            {                skins = value;            }        }        //函数：哺乳        public void Scukle()        {            Console.WriteLine("哺乳");        }        //函数：奔跑        public void Run()        {            Console.WriteLine("奔跑");        }    }}</span>
