?? 在設定的時間結束后，執行相應的方法。
??? 使用metro的Windows.System.Threading命名空間下的ThreadPoolTimer類，可以創建一個Timer。
??? CreateTimer創建一個使用一次的Timer
??? CreatePeriodicTimer創建一個Periodic的Timer，這個方法創建的Timer才和VC中的Timer類似。

??? C#代碼如下：
??? 1.添加Timer相關的namespace
??? using Windows.UI.Core;
??? using Windows.System.Threading;
???
?namespace Timer
{
??? partial class MainPage
??? {
??????? private ThreadPoolTimer DelayTimer;
??????? private CoreDispatcher SampleDispatcher;
?????? private TimerElapsedHandler TimerHandle;
??????? private TimeSpan timespace;

??????? public MainPage()
??????? {
??????????? InitializeComponent();

??????????? // responsible for processing the window messages and dispatching the events to the client.
??????????? SampleDispatcher = Window.Current.CoreWindow.Dispatcher;
??????? }

??????? private void Button_Click(object sender, RoutedEventArgs e)
??????? {
??????????? TimerHandle = new TimerElapsedHandler(MyTimer);
??????????? timespace = TimeSpan.FromMilliseconds(5000);??? //設定的Timer時間(毫秒)

??????????? DelayTimer = ThreadPoolTimer.CreateTimer(TimerHandle, timespace);????????????????????????????????????
??????? }

??????? private void MyTimer(ThreadPoolTimer timer)
??????? {
??????????? SampleDispatcher.InvokeAsync(CoreDispatcherPriority.Normal,
???????????????????????????? (sender, args) =>
???????????????????????????? {?????????????????????????
???????????????????????????????? //Add your code
?????????????????????????????? ?。。。
???????????????????????????? },
???????????????????????????? timer,
???????????????????????????? null);
??????? }

?????
??? }
}
