问题描述

我有一个文件格式 gif 我把它放在 mediaelement 中，动画有效，但如何使该文件连续播放

I have a file format gif I put it in mediaelement, animation worked, but how to make that file was played continuously

推荐答案

您可以使用 MediaTimeline 元素使动画永远循环:

You can use a MediaTimeline element to make the animation loop forever:

<MediaElement Name="yourMediaElement">
    <MediaElement.Triggers>
        <EventTrigger RoutedEvent="MediaElement.Loaded">
            <EventTrigger.Actions>
                <BeginStoryboard>
                    <Storyboard>
                        <MediaTimeline Source="YourAnimation.gif"
                            Storyboard.TargetName="yourMediaElement"  
                            RepeatBehavior="Forever" />
                    </Storyboard>
                </BeginStoryboard>
            </EventTrigger.Actions>
        </EventTrigger>
    </MediaElement.Triggers>
</MediaElement>

上述解决方案似乎不适用于大小超过几千字节的 GIF 文件.这个问题显然来自 Windows Media Player(它可以用 WMP 本身重现).所以，YMMV.

The solution above does not seem to be working with GIF files whose size exceeds a few kilobytes. The issue apparently come from Windows Media Player (it can be reproduced with WMP itself). So, YMMV.
