DispatcherTimer和Timer的区别

两者区别是 Timer在非UI线程跑的，DispatcherTimer是在UI线程跑的，

DispatcherTimer 可以直接更新UI

Timer必须使用this.Dispatcher.BeginInvoke去更新UI

private void DisPatcherTimerMethod()

{

DispatcherTimer timer = new DispatcherTimer();

timer.Interval = TimeSpan.FromMilliseconds(1000);

timer.Tick += Timer_Tick;

timer.Start();

}

private void Timer_Tick(object sender, EventArgs e)

{

this.label1.Text = DateTime.Now.ToString();

}

private void TimerMethod()

{

System.Timers.Timer tmr = new System.Timers.Timer(1000); //1秒一个循环

tmr.Elapsed += tmr_Elapsed;

tmr.Start();

}

private void tmr_Elapsed(object sender, System.Timers.ElapsedEventArgs e)

{

this.Dispatcher.BeginInvoke(new Action(() =>

{

this.label2.Text = DateTime.Now.ToString();

}), null);

}
