在同一个程序中的多个定时器

Question

我想用2个定时器在不同的时间间隔运行一个程序。目前我有1个计时器工作正常，我需要有另一个运行。我对于工作的第一定时器的代码如下所示：

private void startButton_Click(object sender, RoutedEventArgs e) 
    { 
     Random rand = new Random(); 
     int ranMin = rand.Next(1,24); 
     int ranSec = rand.Next(0, 59); 


     System.Windows.Threading.DispatcherTimer dispatcherTimer = new System.Windows.Threading.DispatcherTimer(); 
     dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick); 
     dispatcherTimer.Interval = new TimeSpan(0, ranMin, ranSec); 
     dispatcherTimer.Start(); 

     min.Content = ranMin; 
     sec.Content = ranSec; 

     openP(); 

    } 

    private void dispatcherTimer_Tick(object sender, EventArgs e) 
    { 
     **code for timer in here 
    } 

这工作得很好，但现在我需要另一个定时器以不同代码1秒区间运行，当我试图仅通过所有使dispatcherTimer复制此进入dispatcherTimer2我遇到了错误。

我不知道你在做什么（你应该张贴的错误），但与你提供的代码了以下工作：

private void startButton_Click(object sender, RoutedEventArgs e) 
     { 
      Random rand = new Random(); 
      int ranMin = rand.Next(1,24); 
      int ranSec = rand.Next(0, 59); 


      System.Windows.Threading.DispatcherTimer dispatcherTimer = new System.Windows.Threading.DispatcherTimer(); 
      dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick); 
      dispatcherTimer.Interval = new TimeSpan(0, ranMin, ranSec); 
      dispatcherTimer.Start(); 

      // New timer 
      System.Windows.Threading.DispatcherTimer dispatcherTimer2 = new System.Windows.Threading.DispatcherTimer(); 
      dispatcherTimer2.Tick += new EventHandler(dispatcherTimer2_Tick); 
      dispatcherTimer2.Interval = new TimeSpan(0, 0, 1); 
      dispatcherTimer2.Start(); 

      min.Content = ranMin; 
      sec.Content = ranSec; 

      openP(); 

     } 

     private void dispatcherTimer_Tick(object sender, EventArgs e) 
     { 
      //code for timer in here 
     } 

     private void dispatcherTimer2_Tick(object sender, EventArgs e) 
     { 
      //code for timer2 in here 
     }
