在wpf中如何让MediaElement的视频循环播放

MediaElement原始的播放是只播放一遍；如何设置让MediaElement播放 的视频或者音频循环播放，解决如下：

修改MediaElement模版

 <MediaElement  Name="myMediaElement" Margin="13,35,14,0"  Height="100" VerticalAlignment="Top">

            <MediaElement.Triggers>

                <EventTrigger RoutedEvent="MediaElement.Loaded">

                    <EventTrigger.Actions>

                        <BeginStoryboard>

                            <Storyboard>

                                <MediaTimeline Source="banner[2].avi" Storyboard.TargetName="myMediaElement"  

                 RepeatBehavior="Forever" />

                            </Storyboard>

                        </BeginStoryboard>

                    </EventTrigger.Actions>

                </EventTrigger>

            </MediaElement.Triggers>

        </MediaElement>
