SL中利用StoryBoard实现类似html中的Marquee滚动效果，以下是核心代码：

<Canvas x:Name="c1" Margin="2,25,2,2"><br /> <Canvas.Triggers><br /> <EventTrigger RoutedEvent="Canvas.Loaded" ><br /> <BeginStoryboard><br /> <Storyboard x:Name="animation" RepeatBehavior="Forever" ><br /> <DoubleAnimation Storyboard.TargetName="ScrollingUp"<br /> Storyboard.TargetProperty="(Canvas.Top)" From="120" To="0" Duration="0:0:10" /><br /> </Storyboard><br /> </BeginStoryboard><br /> </EventTrigger><br /> </Canvas.Triggers><br /> <TextBlock x:Name="ScrollingUp" FontWeight="Bold" Foreground="Red" FontSize="12" TextWrapping="Wrap" Height="113"><br /> 从下往上滚动的文字<br /> </TextBlock><br /> </Canvas>

这里是滚动文字的代码，主要的就是StoryBoard里的属性设置:

Storyboard.TargetProperty="(Canvas.Top)" From="100" To="0" Duration="0:0:10"

同理，其他方向如下设置即可：

Storyboard.TargetProperty="(Canvas.Top)" From="0" To="100" Duration="0:0:10"   //从上往下滚动

Storyboard.TargetProperty="(Canvas.Left)" From="0" To="100" Duration="0:0:10"   //从左往右滚动

Storyboard.TargetProperty="(Canvas.Left)" From="100" To="0" Duration="0:0:10"   //从右往左滚动
