继承 示例1

创建枚举类

namespace Main
{
    class Class1
    {
    }

    public enum Gender { 
      male,female
    }
    public enum Popularity { 
    
    }
}

创建父类

namespace Main
{
    public class Employee
    {
        public string  ID { get; set; }
        public int Age { get; set; }
        public string Name { get; set; }
        public Gender Gender { get; set; }
        public int Popularity { get; set; }
    }
}

创建SE类:程序员

namespace Main
{
    public class SE:Employee 
    {
         //带参构造函数,仍然可以调用抽取到Employment类中的属性
        public SE(string id,string name,int age,Gender gender,int popularity)
        {
            this.ID = id;
            this.Name = name;
            this.Age = age;
            this.Gender = gender;
            this.Popularity = popularity;
        }
        public SE()
        {
        }
        //人气值
        private int _popularity;
        public int Poplarity
        {
            get { return _popularity; }
            set { _popularity = value; }
        }
        public string SayHi()
        {
            string message = string.Format("大家好,我是{0},今年{1}年,工号是{2},我的人气值高达{3}!", this.Name, this.Age, this.ID, this.Popularity);
            return message;
        }
    }
}

创建PM类:项目经理

namespace Main
{
    public class MP:Employee
    {
         //带参构造函数,仍然可以调用抽取到Employment类中的属性
        public MP(string id,string name,int age,Gender gender,int yearOfExperience)
        {
            this.ID=id;
            this.Name=name;
            this.Age=age;
            this.Gender=gender;
            this.YearOfExperience=yearOfExperience;
        }
        public MP()
        {
           //无参构造函数
        }
        private int _yearOfExperience;
        //资历       
        public int YearOfExperience
        {
            get {return _yearOfExperience; }
            set{_yearOfExperience =value;}
        }
        public string SayHi()
        {
            string message;
            message=string .Format("大家好,我是{0},今年{1},项目管理经验{2}年。",this.Name ,this.Age ,this.YearOfExperience);
            return message ;
        }
    }
}

在测试类Main()中调用

namespace Main
{
    class Program
    {
        static void Main(string[] args)
        {
            //实例化一个SE对象
            SE engineer = new SE("112","艾边成",25,Gender.male,100);
            Console.WriteLine(engineer .SayHi());
            //实例化一个MP对象
            MP pm = new MP("890","盖茨",50,Gender.female,30);
            Console.WriteLine(pm.SayHi());
            Console.ReadLine();
        }
    }
}

输出结果
