我有一个计时器对象，我想定期更新一个作为标签的UI控件。但是它崩溃了，并说我需要在UI线程上更新它。有人能帮忙吗？

private void frmMain_Load(object sender, EventArgs e)

        aTimer = new System.Timers.Timer(1000);          
        aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
        aTimer.Interval = 2000;
        aTimer.Enabled = true;
   }
   public void updateUI()
    {

        lblAirTrack.Text ="Tracking:" + itemList.Count +" items";

(P)如果你用的是Net 3.5+，请使用"dispatcher"。Otherwise some thing like this should work：(p)字母名称

(P)For WPF，use a dispatcherttimer，for windows forms，I think system.windows.forms.timer should do what you're looking for.(p)(P)The difference of these two timers to the system.timers.timer-class is，that they raise the tick-event in the ui thread.如果你使用这个系统，Timers.Timer，you have to manually route your calls to ui elements to the UI thread.In WPF，use the dispatcher to do this.Usespatcher.Beginnivoke()。In winforms use control.Beginnivoke()(p)
