利用线程池ping多个ip

如题

代码如下：

static void Main(string[] args)
        {
            //ThreadPool.SetMaxThreads(2, 1);
            for (int i = 150; i <= 190; i++)
            {
                //ThreadPool.QueueUserWorkItem(new WaitCallback(pingit), "120.27.234." + i);
                pingit("120.27.234." + i);
            }
            Console.ReadKey();
        }
        static void pingit(object x)
        {
            string y = (string)x;
            Ping ping = new Ping();
            PingReply pr;
            pr = ping.Send(y);
            if(pr.Status==IPStatus.Success)
            {
                Console.WriteLine($"{y} is alive.");
            }
            else
            {
                Console.WriteLine($"{x.ToString()}");
            }
        }
