推荐答案

您可以直接从视图模型中绑定媒体元素

You can bind Media Element directly from the view model

xaml:

<ContentControl Content="{Binding MediaElementObject}"/>

在ViewModel中:

private MediaElement _mediaElementObject; public MediaElement MediaElementObject { get { return _mediaElementObject; } set { _mediaElementObject = value;RaisePropertyChanged(); } }

在OnNavigatedTo覆盖方法上，您可以创建它的新对象&可以注册它的事件.

And on OnNavigatedTo Override method you can create it's new object & can register it's events.

MediaElementObject=new MediaElement();

这样您就可以从viewmodel本身做所有事情.

So that you can do all thing from the viewmodel itself.
