如何：重复媒体播放

此示例演示如何无限期播放媒体，即设置媒体，使其在无限循环中播放。

示例：

以下示例在无限循环中使用 MediaElement 和 MediaTimeline 播放 Storyboard 媒体剪辑。

<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" >
  <StackPanel>

    <!-- The MediaElement control plays the sound. -->
    <MediaElement Name="myMediaElement" >
      <MediaElement.Triggers>
        <EventTrigger RoutedEvent="MediaElement.Loaded">
          <EventTrigger.Actions>
            <BeginStoryboard>
              <Storyboard>

                <!-- The MediaTimeline has a RepeatBehavior="Forever" which makes the media play
                     over and over indefinitely.-->
                <MediaTimeline Source="media\tada.wav" Storyboard.TargetName="myMediaElement"  
                 RepeatBehavior="Forever" />

              </Storyboard>
            </BeginStoryboard>
          </EventTrigger.Actions>
        </EventTrigger>
      </MediaElement.Triggers>
    </MediaElement>

  </StackPanel>
</Page>
