Windows Phone 實用開發技巧（21）：自動循環播放視訊

In WPF or Silverlight, we can use following code to repeat media playback.

<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>

 In windows phone , I find simple solution to play video in a loop. Since we can catch Media_End event, we can play again in ended event.

Another suggestion : do not play large video in your windows phone app since it will cause a little bit performance damage.
