C# 在wpf中启动后停止情节提要

我使用了一个故事板来闪烁

图像

。我已经在XAML上定义了情节提要：

<UserControl.Resources>
    <Storyboard x:Key="AnimateFlicker" RepeatBehavior="Forever">
        <DoubleAnimation Storyboard.TargetProperty="Opacity"
                 From="0"
                 To="1"
                 AutoReverse="True"
                 BeginTime="0:0:1"
                 Duration="0:0:0.08" />
        <DoubleAnimation Storyboard.TargetProperty="Opacity"
                 From="1"
                 To="1"
                 AutoReverse="True"
                 Duration="0:0:0.4" />
        <DoubleAnimation Storyboard.TargetProperty="Opacity"
                 From="1"
                 To="0"
                 AutoReverse="True"
                 Duration="0:0:0.08" />
    </Storyboard>
</UserControl.Resources>

但正如我在代码

情节提要中提到的，Stop（）

不起作用，闪烁仍在继续。启动后如何停止闪烁？

调用<代码>情节提要。开始然后<代码>情节提要。暂停或<代码>情节提要。暂停取决于您是否希望动画目标属性仍受影响：

private void Blink(bool blink)
{
    Storyboard storyboard = TryFindResource("AnimateFlicker") as Storyboard;
    if (blink)
    {
        if (storyboard != null)
        {
            storyboard.Begin(imgState, HandoffBehavior.SnapshotAndReplace, true);
        }
    }
    else
    {
        storyboard.Pause(imgState);
    }
}

private void Blink(bool blink)
{
    Storyboard storyboard = TryFindResource("AnimateFlicker") as Storyboard;
    if (blink)
    {
        if (storyboard != null)
        {
            storyboard.Begin(imgState, HandoffBehavior.SnapshotAndReplace, true);
        }
    }
    else
    {
        storyboard.Pause(imgState);
    }
}
