Asp.net中使用定时器

   protected void Page_Load(object sender, EventArgs e)
    {
        System.Timers.Timer aTimer = new System.Timers.Timer(1000);
        aTimer.Elapsed += new System.Timers.ElapsedEventHandler(OnTimedEvent);
        aTimer.AutoReset = false;
        aTimer.Enabled = true;
        System.Threading.Thread.Sleep(1500);
     }

    private void OnTimedEvent(object sender, System.Timers.ElapsedEventArgs e)
    {
        Response.Write("定时器已触发!");
    }
