MaualResetEventSlim沒有停止線程

我已經在我的示例應用程序下面的代碼：MaualResetEventSlim沒有停止線程

private static ManualResetEventSlim _screenSaverOn = new ManualResetEventSlim(); 
private static ManualResetEventSlim _screenSaverOff = new ManualResetEventSlim();

在我已經初始化兩個線程類的構造函數：由這些線程執行

Thread threadOn = new Thread(CheckIfScreenSaverIsOn) {IsBackground = true}; 
Thread threadOff = new Thread(CheckIfScreenSaverIsOff) {IsBackground = true}; 

threadOn.Start(); 
threadOff.Start();

的方法是：

private static void CheckIfScreenSaverIsOn() 
{ 
    log.Info("Thread1 - started running"); 
    while (true) 
    { 
     if (NativeMethods.IsScreensaverRunning()) 
     { 
      log.Info("Thread1 - Screen Saver Started Running"); 
      _screenSaverOff.Set(); 
      log.Info("Thread1 - Waiting"); 
      _screenSaverOn.Wait(); 
      log.Info("Thread1 - Started Again"); 
     } 

     Thread.Sleep(2000); 
    } 
} 

private static void CheckIfScreenSaverIsOff() 
{ 
    log.Info("Thread2 - Started Running"); 
    _screenSaverOff.Wait(); 

    while (true) 
    { 
     // returns true/false 
     if (!NativeMethods.IsScreensaverRunning()) 
     { 
      log.Info("Thread2 - Screen Saver Stopped Running"); 
      _screenSaverOn.Set(); 
      log.Info("Thread2 - Waiting"); 
      _screenSaverOff.Wait(); 
      log.Info("Thread2 - Started Again"); 
     } 

     Thread.Sleep(2000); 
    } 
}

我面臨的問題是，「thread2」沒有得到即使在調用_screenSaverOff.Wait（）方法後也會被阻止。登錄如下條目：

**手動**重置事件，並且在您的代碼中沒有看到任何對這些事件調用「重置」的任何事件 - 一旦它們被設置，它們就會保持設置。 –

您使用手動復位的事件，但你永遠不進行重置。你需要撥打Reset，否則他們會一直保持信號，一旦你設置了它們。
