2. ManualResetEvent详解

    ManualResetEvent 允许线程通过发信号互相通信。通常,此通信涉及一个线程在其他线程进行之前必须完成的任务。当一个线程开始一个活动(此活动必须完成后,其他线程才能开始)时,它调用 Reset 以将 ManualResetEvent 置于非终止状态,此线程可被视为控制 ManualResetEvent。调用 ManualResetEvent 上的 WaitOne 的线程将阻止,并等待信号。当控制线程完成活动时,它调用 Set 以发出等待线程可以继续进行的信号。并释放所有等待线程。一旦它被终止,ManualResetEvent 将保持终止状态(即对 WaitOne 的调用的线程将立即返回,并不阻塞),直到它被手动重置。可以通过将布尔值传递给构造函数来控制 ManualResetEvent 的初始状态,如果初始状态处于终止状态,为 true;否则为 false。
