如何在WPF中停止Storyboard？

Question

我有一个动画 但我无法阻止它 因为故事板重复行为属性是“永远” 如何从代码后面停止动画？

这是我的XAML：

<UserControl.Resources>
    <Storyboard x:Name="loadingAnimation" x:Key="LoadingAnimation" RepeatBehavior="Forever" SpeedRatio="1" AutoReverse="True">
        <DoubleAnimationUsingKeyFrames x:Name="doubleAnimationUsingKeyFrames" Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="pathListBox">
            <EasingDoubleKeyFrame KeyTime="0" Value="0"/>
            <EasingDoubleKeyFrame KeyTime="0:0:1" Value="1"/>
        </DoubleAnimationUsingKeyFrames>
        <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[2].(RotateTransform.Angle)" Storyboard.TargetName="ellipse">
            <EasingDoubleKeyFrame KeyTime="0:0:1" Value="293.73">
                <EasingDoubleKeyFrame.EasingFunction>
                    <BackEase EasingMode="EaseOut"/>
                </EasingDoubleKeyFrame.EasingFunction>
            </EasingDoubleKeyFrame>
            <EasingDoubleKeyFrame KeyTime="0:0:2" Value="560.097"/>
        </DoubleAnimationUsingKeyFrames>
    </Storyboard>
</UserControl.Resources>
