C# .net非窗体实战五：抽象类和抽象方法——作业

题目：

代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace _22
{
    abstract class Person
    {
        protected string Name;
        public Person(string name)
        {
            Name = name;
        }
        public abstract void Display();//抽象类里面没有任何东西！！
        //所以一定要在子类中进行override
    }

    class Man : Person
    {
        public Man(string name) : base(name) { }
        public override void Display()
        {
            Console.WriteLine("这位男士的姓名是 " + Name);
        }
    }

    class Woman : Person
    {
        public Woman(string name) : base(name) { }
        public override void Display()
        {
            Console.WriteLine("这位女士的姓名是 " + Name);
        }
    }
    internal class Program
    {
        static void Main(string[] args)
        {
            Console.Write("请输入姓名: ");
            string manName = Console.ReadLine();
            Man p = new Man(manName);
            p.Display();

            Console.WriteLine("");
            Console.Write("请输入姓名: ");
            string womanName = Console.ReadLine();
            Woman q = new Woman(womanName);
            q.Display();

            Console.ReadLine();
        }
    }
}
