Question

我试图在点击一个按钮然后播放媒体时给MediaElement一个源，这是我到目前为止所做的：

在我的XAML中：

<MediaElement x:Name="vid" HorizontalAlignment="Left" Height="100" Margin="310,193,0,0" Grid.Row="1" VerticalAlignment="Top" Width="100" Source="Assets/Stars.mov"/>

在课堂上：

private void Button1_Click(object sender, RoutedEventArgs e)
    {
        this.vid.Source = new Uri("Assets/Stars.mov", UriKind.Relative);
        vid.Play();
    }

但是我收到此错误：

An exception of type 'System.ArgumentException' occurred in mscorlib.dll but was not handled in user code
Additional information: The given System.Uri cannot be converted into a Windows.Foundation.Uri. Please see http://go.microsoft.com/fwlink/?LinkID=215849 for details.

有谁知道我做错了什么？

Programmatically set the Source of an Image (XAML)

希望这会有所帮助
