我应该担心停止/处理WPF动画吗？

Question

我有一个UserControl加载时开始:

<Storyboard x:Key="StFlash" RepeatBehavior="Forever" AutoReverse="True" >
    <DoubleAnimation Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="img" From=".3" To="1" Duration="0:0:0.6">
        <DoubleAnimation.EasingFunction>
            <CircleEase EasingMode="EaseOut"/>
        </DoubleAnimation.EasingFunction>
    </DoubleAnimation>
</Storyboard>

基本上它会使图像永远闪烁. When I remove that user control should I worry about stopping the animation?

Answer 1

是的,有可能你必须停止动画,因为它将被播放,直到垃圾收集器不会破坏你的UserControl,它可能需要一些时间.为此,您可以将Unloaded事件用于UserControl.
