namespace 时钟
{
public partial class MainPage : PhoneApplicationPage
{
// 构造函数
int a=0;
public MainPage()
{
InitializeComponent();
//创建DispatcherTimer
DispatcherTimer timer = new DispatcherTimer();
//设置间隔1秒
timer.Interval = new TimeSpan(0, 0, 1);
//创建事件处理
timer.Tick += new EventHandler(timer_Tick); //此处按两下Tab键即可将事件加上去。。
//开始计时
timer.Start();
}

private void timer_Tick(object sender, EventArgs e)
{
a += 1;

tbkTimer.Text = a.ToString();

}

}
