執行的方法只有

Question

我用這個方法來調用另一個方法每60秒：

Timer updateTimer = new Timer(testt, null, 
           new TimeSpan(0, 0, 0, 0, 1), new TimeSpan(0, 0, 60)); 

是可能的1毫秒的延遲之後只有一次調用此方法？

Answer 1

假設這是一個System.Threading.Timer，從爲constructor的最後一個參數的文件：

period
The time interval between invocations of the methods referenced by callback. Specify negative one (-1) milliseconds to disable periodic signaling.

所以：

Timer updateTimer = new Timer(testt, null, 
           TimeSpan.FromMilliseconds(1), // Delay by 1ms 
           TimeSpan.FromMilliseconds(-1)); // Never repeat 

是真正有用的，雖然1毫秒的延遲？爲什麼不立即執行它？如果你真的只是試圖在線程池線程上執行它，那麼有更好的方法來實現它。

Answer 2

System.Timers.Timer aTimer = new System.Timers.Timer(10000); 
// Hook up the Elapsed event for the timer. 
aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent); 
// Set the Interval to 60 seconds (60000 milliseconds). 
aTimer.Interval = 60000; 
//for enabling for disabling the timer. 
aTimer.Enabled = true; 
private void OnTimedEvent(object source, ElapsedEventArgs e) 
{ 
    //disable the timer 
    aTimer.Enabled = false; 
    Console.WriteLine("The Elapsed event was raised at {0}", e.SignalTime); 
}
