 mm.Volume = 0.7;
 mm.Play();

但是没有任何变化，adudio无法启动.我该如何解决?

But no changes, the adudio not starts.How I can resolve this?

推荐答案

您需要在播放MediaTree之前将其添加到VisualTree中，因为您是在背后的代码中创建它的.例如，假设您有LayoutRoot并且您的url是正确的，那么这应该可以工作.

You need to add your MediaElement to your VisualTree before playing it, since you're creating it in the codebehind. For example, assuming you have LayoutRoot and that your url is correct, this should work.

string url = re["response"][0]["url"].ToString();
MediaElement mm = new MediaElement();
mm.Source = new Uri(url,UriKind.RelativeOrAbsolute);
mm.AutoPlay = true;
mm.Volume = 0.7;
LayoutRoot.Children.Add(mm);
mm.Play();
