        newTimer.Interval = TimeSpan.FromSeconds(1);

        newTimer.Start();
    }

 void OnTimerTick(Object sender, EventArgs args)
    {
        clock.Text = DateTime.Now.ToString();
    }

推荐答案

//make global declaration of a counter variable 


 int counter =60;    
    void OnTimerTick(Object sender, EventArgs args)
       {       
         counter --;
         if(counter<0)
         {
          newTimer.Stop();
          counter=60;
         }
        else
         {
          clock.Text =counter.ToString();
         }
       }
