WP7实现 简单的计时器。。

 

前台代码：

<phone:PhoneApplicationPage
x:Class="时钟.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"

FontSize="{StaticResource PhoneFontSizeNormal}"
Foreground="{StaticResource PhoneForegroundBrush}"
SupportedOrientations="Portrait" Orientation="Portrait"
shell:SystemTray.IsVisible="True">
<Grid x:Name="LayoutRoot" Background="White">
<!--背景-->
<Rectangle Fill="Gold" Stroke="Black"
StrokeThickness="3"
RadiusX="5" RadiusY="5"/>
<!--显示时间-->
<TextBlock x:Name="tbkTimer"
Width="300" Height="50"

</Grid>

 

 

后台CS代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;
using System.Windows.Threading;

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();

}

}
}
