static void Main(string[] args)
        {
            Console.Write("请输入此次活动人数：");
            int ren = int.Parse(Console.ReadLine());
            //根据人数定数组长度
            string[] shuzu = new string[ren];
            //循环输入所有手机号码
            for (int i = 0; i < shuzu.Length; i++)
            {
                Console.Write("请输入第{0}个人的手机号：", i + 1);
                shuzu[i] = Console.ReadLine();
            }
            //提示输入完成
            Console.WriteLine("所有参与者的手机号码输入完成");
            Console.ReadLine();
            //初始化随机数
            Random ran = new Random();
            //循环滚动手机号
            for (int i = 0; i < 500; i++)
            {
                Console.Clear();//清屏
                int aa = ran.Next(ren);//随机数
                Console.WriteLine("中奖号码：" + shuzu[aa]);
                System.Threading.Thread.Sleep(5);
                //打印并休息5MS
            }
            //作弊代码
            //Console.Clear();
            //Console.WriteLine("中奖号码：157****2915");
