silverlight使用定时器右下角定时弹窗，模拟信息报警。

代码如下：

        <Canvas.Resources>
            <Storyboard x:Name="storyPopUp">
                <DoubleAnimation Duration="0:0:2" From="0" To="-200" Storyboard.TargetName="canvasPopup" Storyboard.TargetProperty="(Canvas.Top)" />
            </Storyboard>
            <Storyboard x:Name="storyPopDown">
                <DoubleAnimation Duration="0:0:2" From="-200" To="0" Storyboard.TargetName="canvasPopup" Storyboard.TargetProperty="(Canvas.Top)" />
            </Storyboard>
        </Canvas.Resources>
        <Canvas VerticalAlignment="Bottom" HorizontalAlignment="Right" x:Name="canvasPopup" Margin="-200 0 0 0" Width="200" Height="200">
            <Border BorderThickness="1,1,1" Background="Azure" HorizontalAlignment="Right" VerticalAlignment="Top"
                    BorderBrush="Gold" Width="200" Height="200">
                <Border.Effect>
                    <DropShadowEffect />

后台代码：

System.Windows.Threading.dispatcherTimer gapTimer;

 void initAlarmTimer()         {             gapTimer = new System.Windows.Threading.dispatcherTimer();             gapTimer.Interval = new TimeSpan(0,10);             gapTimer.Tick += new EventHandler(gapTimer_Tick);             gapTimer.Start();         }         void gapTimer_Tick(object sender,EventArgs e)         {             popAlarm();         }         #region 报警信息         private void popAlarm()         {             storyPopUp.Begin();             alarmTitle.Text = "报警类型";             alarmContent.Text = "警情明细" + DateTime.Now.ToLongTimeString();             System.Windows.Threading.dispatcherTimer timer = new System.Windows.Threading.dispatcherTimer();             timer.Interval = new TimeSpan(0,4500);             timer.Tick += new EventHandler((sender2,e2) =>             {                 storyPopUp.Stop();                 storyPopDown.Begin();                 timer.Stop();             });             timer.Start();         }
