线程如何挂起和继续？要使用最新的模式，也就是System.Threading.Monitor

//Create the second thread.

Thread tSecond = new Thread(new ThreadStart(test.SecondThread));

//Start threads.

tFirst.Start();

tSecond.Start();

//wait to the end of the two threads

tFirst.Join();

tSecond.Join();

//Print the number of queue elements.

Console.WriteLine("Queue Count = " + test.GetQueueCount().ToString());

Console.ReadLine();

}

}

}
