[多线程] WaitHandle.WaitAll ManualResetEvent 等待所有线程完成

            Thread[] threads = new Thread[30];
            ManualResetEvent[] events = new ManualResetEvent[10];
            for (int i = 0; i < threads.Length; i++)
            {
                events[i] = new ManualResetEvent(false);
                threads[i] = new Thread(worker(events[i]));  // call events[i].Set() when the task is done.
                threads[i].Start();
            }
            WaitHandle.WaitAll(events);

或者

            for (int i = 0; i < threads.Length; i++)
            {
                threads[i].Join();
            }
