Silverlight实现滚动文字

主要是用到DoubleAnimation 标签：

<Canvas x:Name="c1" Margin="2,25,2,2">
            <Canvas.Triggers>
                <EventTrigger RoutedEvent="Canvas.Loaded" >
                    <BeginStoryboard>
                        <Storyboard x:Name="animation" RepeatBehavior="Forever" >
                            <DoubleAnimation Storyboard.TargetName="ScrollingUp"
                                             Storyboard.TargetProperty="(Canvas.Left)" From="1024" To="0" Duration="0:0:15"  />
                        </Storyboard>
                    </BeginStoryboard>
                </EventTrigger>
            </Canvas.Triggers>
            <TextBlock x:Name="ScrollingUp" FontWeight="Bold" Foreground="Red"  FontSize="12" TextWrapping="Wrap" Height="113">
                滚动文字

            </TextBlock>
        </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
