WPF动画暂停/继续

Kaxaml 要尝试:

<Page
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  <Grid Background="Red">  
    <Grid.Triggers>
      <EventTrigger RoutedEvent="Grid.Loaded">
        <EventTrigger.Actions>
          <BeginStoryboard>
            <Storyboard RepeatBehavior="Forever">
              <DoubleAnimation Storyboard.TargetProperty="Opacity"
                               From="1" To="0" 
                               Duration="0:00:02"
                               BeginTime="0:00:02" />
            </Storyboard>
          </BeginStoryboard>
        </EventTrigger.Actions>
      </EventTrigger>
    </Grid.Triggers>
  </Grid>
</Page>

诀窍是使用 BeginTime DoubleAnimation
