c# – 停止WPF动画,故事板以xaml开头,但在代码隐藏中停止？

我在xaml文件中创建了一个动画故事板.那个故事板开始于Button.Click.但是为了停止动画,我试图在代码背后的自定义事件上停止故事板.
代码没有抛出任何异常但是当我的事件被触发时,动画仍然继续.

我认为问题在于Stop方法.停止需要与开始动画相同的对象来停止它.但是这里的故事板是从WPF xaml开始的,我在后面的代码中停止它.

任何解决方案,如何在代码中获取Xaml对象或任何替代解决方案？

XAML代码：

<Canvas.Triggers>
            <EventTrigger RoutedEvent="Button.Click" SourceName="ScanButton">
                <EventTrigger.Actions>
                    <BeginStoryboard >
                        <Storyboard  Name="MovingServer" Storyboard.TargetName="ImageMove" RepeatBehavior="Forever" >
                            <DoubleAnimation Storyboard.TargetProperty="(Canvas.Left)" Duration="0:0:2" From="30" To="300" BeginTime="0:0:0" />
                            <DoubleAnimation Storyboard.TargetProperty="(Canvas.Left)" Duration="0:0:5" From="300" To="300" BeginTime="0:0:5" />
                            <DoubleAnimation Storyboard.TargetProperty="(Canvas.Left)" Duration="0:0:2" From="300" To="600" BeginTime="0:0:7" />
                            <DoubleAnimation Storyboard.TargetProperty="Opacity" Duration="0:0:2" From="1" To="0" BeginTime="0:0:7" />
                        </Storyboard>
                    </BeginStoryboard>
                </EventTrigger.Actions>
            </EventTrigger>

代码背后：

private void EventPublisher_OnScanningFinish(object sender,EventArgs args)
    {
        dispatcher.Invoke(dispatcherPriority.normal,(Action)delegate() { this.StopScanningAnimation(); });
    }

    private void StopScanningAnimation()
    {

        ServerView.StoryBoardServerScrolling.Stop(this); //---------- Not Working

        //this.ServerView.Server1Static.Visibility = System.Windows.Visibility.Hidden;
        //this.ServerView.Server2Static.Visibility = System.Windows.Visibility.Hidden;
        //this.ServerView.Server3Scrolling.Visibility = System.Windows.Visibility.Hidden;
        //this.ServerView.SearchingGlass.Visibility = System.Windows.Visibility.Hidden;
    }

<MyControl.Resources>
                        <Storyboard Key="MovingServer" Storyboard.TargetName="ImageMove" RepeatBehavior="Forever" >
                            <DoubleAnimation Storyboard.TargetProperty="(Canvas.Left)" Duration="0:0:2" From="30" To="300" BeginTime="0:0:0" />
                            <DoubleAnimation Storyboard.TargetProperty="(Canvas.Left)" Duration="0:0:5" From="300" To="300" BeginTime="0:0:5" />
                            <DoubleAnimation Storyboard.TargetProperty="(Canvas.Left)" Duration="0:0:2" From="300" To="600" BeginTime="0:0:7" />
                            <DoubleAnimation Storyboard.TargetProperty="Opacity" Duration="0:0:2" From="1" To="0" BeginTime="0:0:7" />
                        </Storyboard>
</MyControl.Resources>

StoryBoard board = (StoryBoard)this.FindResource("MovingServer");
board.stop();

<Button x:Name="ScanButton" onClick="Scanbutton_Click"></button>


protected void Scanbutton_Click(object Sender,EventArgs e)
{
    StoryBoard board = (StoryBoard)this.FindResource("MovingServer");
    board.start();
}
