線程池是單例，一個進程里只有一個線程池

private void btnThreadPool_Click(object sender, EventArgs e){Stopwatch watch = new Stopwatch();watch.Start();Console.WriteLine();Console.WriteLine("****************btnThreadPool_Click Start 主線程id={0}*****************", Thread.CurrentThread.ManagedThreadId);List<ManualResetEvent> mreList = new List<ManualResetEvent>();for (int i = 0; i < 5; i++){int b = i;mreList.Add(new ManualResetEvent(false));WaitCallback method = t =>{this.TestThreadWithoutReturn(string.Format("btnThreadPool_Click_{0}", b));Console.WriteLine("我是回調 btnThreadPool_Click_{0}", b);mreList[b].Set();};ThreadPool.QueueUserWorkItem(method);//WaitCallback method = t => this.TestThreadWithoutReturn(t.ToString ());//ThreadPool.QueueUserWorkItem(method, string.Format("btnThreadPool_Click_{0}", b));} private void TestThreadWithoutReturn(string name){Console.WriteLine("TestThread Start Name={2},當前線程的id:{0},當前時間為{1}", Thread.CurrentThread.ManagedThreadId, DateTime.Now.ToString("hh:mm:ss:fff"), name);long Sum = 0;for (int i = 1; i < 999999999; i++){Sum += i;}//Thread.Sleep(2000);Console.WriteLine("TestThread End Name={2},當前線程的id:{0},當前時間為{1}", Thread.CurrentThread.ManagedThreadId, DateTime.Now.ToString("hh:mm:ss:fff"), name);}
