C# 随机得到十个人的身份_c#,生成随机身份证

创建一个person类在里面写出一个方法persondoing；

之后student类，man类，women类，zjr类都以person类为父类；

再写出各自的方法；（这里不使用多态）

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
 
namespace 随机得到十个人的身份
{
    public class person
    {
 
        public void persondoing()
        {
            Console.WriteLine("我是人类");
        }
    }
    public class student : person
    {
        public void studentdoing()
        {
            Console.WriteLine("我是学生");
        }
    }
    public class man : person
    {
        public void mandoing()
        {
            Console.WriteLine("我是男人");
        }
    }
 
    public class women : person
    {
        public void womendoing()
        {
            Console.WriteLine("我是女人");
        }
    }
    public class zjr : person
    {
        public void zjrdoing()
        {
            Console.WriteLine("我是神");
        }
    }
 
}

main方法里，创建父类person对象per[]数组， 

using System;
 
namespace 随机得到十个人的身份
{
    internal class Program
    {
        static void Main(string[] args)
        {
            // person p = new person();
            // student s = new student();
            // man m = new man();
            // women w = new women();
            //  zjr z = new zjr();
            person[] per = new person[10];
            Random r = new Random();
            for (int i = 0; i < per.Length; i++)
            {
                int ran = r.Next(1, 6);
                switch (ran)
                {
                    case 1:
                        per[i] = new person();
                        break;
                    case 2:
                        per[i] = new student();
                        break;
                    case 3:
                        per[i] = new man();
                        break;
                    case 4:
                        per[i] = new women();
                        break;
                    case 5:
                        per[i] = new zjr();
                        break;
                }
            }
            for (int i = 0; i < per.Length; i++)
            {
 
                if (per[i] is student)
                {
                    ((student)per[i]).studentdoing();
                }
                else if (per[i] is man)
                {
                    ((man)per[i]).mandoing();
                }
                else if (per[i] is women)
                {
                    ((women)per[i]).womendoing();
                }
                else if (per[i] is zjr)
                {
                    ((zjr)per[i]).zjrdoing();
                }
                else
                    per[i].persondoing();
 
            }
        }
 
    }
}
