在WP7中倒數計時器

我想倒數計時器開始滴答兩個半小時。我試過這個使用調度計時器在WP7中倒數計時器

請找到下面的代碼。但它沒有正確更新秒。它太快了。它一次剔2秒而不是1秒

private void DrawBlackout() 
    { 
     TextBlock videoText = new TextBlock(); 
     dt = new DispatcherTimer(); 
     dt.Interval = new TimeSpan(0,0,1); // 1 Seconds 
     dt.Tick += new EventHandler(dt_Tick); 
     dt.Start(); 


    } 

    void dt_Tick(object sender, EventArgs e) 
    { 
     // do something 

     milliseconds = milliseconds - 1000; 
     label.Text = getTimeText(milliseconds/1000); 
     elapsed += 1000; 

     //Debug.WriteLine(stopwatch.ElapsedMilliseconds + "\n"); 
     if (milliseconds <= 1000) 
      dt.Stop(); 
    } 



    String getTimeText(long secVal) 
    { 

     String timeString = ""; 
     int seconds = (int)(secVal % 60); 
     int minutes = (int)((secVal/60) % 60); 
     int hours = (int)((secVal/(60 * 60)) % 60); 
     if (hours <= 9) 
      timeString = "0" + Convert.ToString(hours) + " : "; 
     else 
      timeString = Convert.ToString(hours) + " : "; 
     if (minutes <= 9) 
      timeString = timeString + "0" + Convert.ToString(minutes) + " : "; 
     else 
      timeString = timeString + Convert.ToString(minutes) + " : "; 
     if (seconds <= 9) 
      timeString = timeString + "0" + Convert.ToString(seconds) + " "; 
     else 
      timeString = timeString + Convert.ToString(seconds) + " "; 
     return timeString; 
    }

請幫忙解決此問題。

它適合我！ –

這是仿真器還是真實設備？ –

而不是假設每個嘀嗒將恰好是1000毫秒，你應該節省開始時間，並在每個滴答聲看到自從開始以來已經過去了多少時間。然後你可以每隔100ms打勾一次，看起來應該很穩定。 –

void DisTimer_Tick(object sender, EventArgs e) 
     { 
      timeRefresh++; 
      if (sec > 0) 
      { 
       sec--; 
      } 
      else if (sec == 0 && min > 0) 
      { 
       sec = 59; 
       min--; 
      } 
      else if (sec == 0 && min == 0 && house > 0) 
      { 
       sec = 59; 
       min = 59; 
       house--; 
      } 
      txtHouse.Text = house.ToString(); 
      txtMin.Text = min.ToString(); 
      txtSec.Text = sec.ToString(); 

      if (sec == 0 && min == 0 && house == 0) 
      { 
       DisTimer.Tick -= new EventHandler(DisTimer_Tick); 
       getBuyer(); 
      } 
      else if (timeRefresh == 60) 
      { 
       getBuyer(); 
       DisTimer.Tick -= new EventHandler(DisTimer_Tick); 
      } 
     }

我希望能幫到你！
