[多线程] ManualResetEvent(线程之间通讯 通知或者查看是否完成)

在别人的基础上修改成ManualResetEvent, 以取代suspend, resume. 

  public class Boy
    {
        private ManualResetEvent ent;
        public Boy(ManualResetEvent e)
        {
            ent = e;
        }
        public void SendFlower()
        {
            Console.WriteLine("正在送花的途中");
            for (int i = 0; i < 10; i++)
            {
                Thread.Sleep(200);
                Console.Write("..");
            }
            Console.WriteLine("花已经送到");
            ent.Set();
        }
    }

    class Program
    {
        private static ManualResetEvent ent = new ManualResetEvent(false);
        static void Main(string[] args)
        {
            Boy sender = new Boy(ent);
            for (int i = 0; i < 2; i++)
            {
                Thread th = new Thread(new ThreadStart(sender.SendFlower));
                th.Start();
                //Console.WriteLine("-before wait?-" + ent.WaitOne(0)); //false
                ent.WaitOne();
                //Console.WriteLine("-before reset?-" + ent.WaitOne(0)); //true
                ent.Reset();
                //Console.WriteLine("-after reset?-" + ent.WaitOne(0)); //false
                Console.WriteLine("收到了吧，花是我送嘀:)/r/n/r/n");
            }
            Console.ReadLine();
        }
    }
