使用Timer。

public static void Main()
{
    System.Timers.Timer aTimer = new System.Timers.Timer();
    aTimer.Elapsed+=new ElapsedEventHandler(OnTimedEvent);
    aTimer.Interval=5000;
    aTimer.Enabled=true;

    Console.WriteLine("Press \'q\' to quit the sample.");
    while(Console.Read()!='q');
}

 // Specify what you want to happen when the Elapsed event is raised.
 private static void OnTimedEvent(object source, ElapsedEventArgs e)
 {
     Console.WriteLine("Hello World!");
 }

用System.Windows.Forms.Timer类：你可以实现你所需要的。

System.Windows.Forms.Timer t = new System.Windows.Forms.Timer();


t.Interval = 15000; // specify interval time as you want
t.Tick += new EventHandler(timer_Tick);
t.Start();

void timer_Tick(object sender, EventArgs e)
{
      //Call method
}

通过使用Stop()方法，可以停止计时器。

t.Stop();
