Semaphore 的使用

var workerSemphore = new Semaphore(0, 800000);
          var IsWorkThreadCreated = true;
          var   workThread = new Thread(() =>
            {
                Console.WriteLine("XiaoweiSDK.CreateWorkerThread created!");
                while (IsWorkThreadCreated)
                {
                    //Debug.WriteLine("lock wait:XiaoweiSDK::CreateWorkerThread");
                    workerSemphore.WaitOne();
                    //Debug.WriteLine("lock enter:XiaoweiSDK::CreateWorkerThread");
                    Console.WriteLine("------------XiaoweiSDK.CreateWorkerThread inside inside inside!");
                }
                Console.WriteLine("XiaoweiSDK.WorkerThread exited!");
            });
            workThread.IsBackground = true;
            workThread.Start();            Console.WriteLine("XiaoweiSDK.WorkerThread Release111111111!");
            workerSemphore.Release();            Console.WriteLine("XiaoweiSDK.WorkerThread Release2222222222");
            workerSemphore.Release();
