WPF MediaElement，如何让重复速度变慢？

Question

每次重复都会延迟。

let mediaTimeline=MediaTimeline([email protected]"...mp3",RepeatBehavior=RepeatBehavior.Forever) 
let storyboard=Storyboard() 
storyboard.Children.Add mediaTimeline 
let mediaElement=MediaElement() 
mediaElement.BeginStoryboard<|storyboard 

（在任何语言接听或WPF标记是欢迎）

你可以这样做：

using System.Threading.Tasks; 

MediaElement me = new MediaElement(); // Make sure add this control to Window or a control. 

me.MediaEnded += me_MediaEnded; 
me.LoadedBehavior = MediaState.Manual; // Must have this line 
// load song... 
me.Play(); 


async void me_MediaEnded(object sender, RoutedEventArgs e) 
{ 
    await Task.Delay(1000); 
    me.Play(); 
} 

注：await需要.Net 4.5。如果.Net版本较低，则可以使用DispatcherTimer代替。
