CountdownEvent的使用正确姿势

 class CountdownEventTest
    {
        const int numIterations = 10;
        static CountdownEvent latch1 = new CountdownEvent(1);

        static void Main()

            //Thread payMoneyThread = new Thread(new ThreadStart(PayMoneyProc));
            //payMoneyThread.Name = "付钱线程";
            //payMoneyThread.Start();

            //latch1.Wait();

            //PayMoneyExit();

            //latch1.Dispose();
            #endregion

            #region 方式二
            CountDownTest();
            #endregion



        }


        #region 方式一
        static void PayMoneyProc()
        {
            for (int i = 1; i <= numIterations; i++)
