wpf - 如何在 WPF 中暂停动画？

Question

假设有一个动画会持续，例如 10 秒，当鼠标进入相关控件时我如何暂停（而不是完全停止）它，然后当鼠标离开时，动画继续完成其余部分？

Answer 1

使用PauseStoryboard和ResumeStoryboard类。例如：

<Control>
    <Control.Triggers>
        <EventTrigger RoutedEvent="Loaded">
            <BeginStoryboard x:Name="theStoryboard">
                ...
            </BeginStoryboard>
        </EventTrigger>
        <EventTrigger RoutedEvent="MouseEnter">
            <PauseStoryboard BeginStoryboardName="theStoryboard"/>
        </EventTrigger>
        <EventTrigger RoutedEvent="MouseLeave">
            <ResumeStoryboard BeginStoryboardName="theStoryboard"/>
        </EventTrigger>
    </Control.Triggers>
</Control>
