使用MediaPlayer播放本地ismv文件

Question

每当我尝试播放本地ismv文件时，我都会收到“System.IO.FileNotFoundException”。这是我的代码

 MediaPlayerLauncher mediaPlayerLauncher = new MediaPlayerLauncher();

 mediaPlayerLauncher.Media = new Uri("To_The_Limit_720_230.ismv", UriKind.Relative);
 mediaPlayerLauncher.Location = MediaLocationType.Data;
 mediaPlayerLauncher.Controls = MediaPlaybackControls.Pause | MediaPlaybackControls.Stop;
 mediaPlayerLauncher.Orientation = MediaPlayerOrientation.Landscape;

 mediaPlayerLauncher.Show();

我在这里做错了什么？

Answer 1

尝试使用UriKind.RelativeOrAbsolute

mediaPlayerLauncher.Media = new Uri("To_The_Limit_720_230.ismv", UriKind.RelativeOrAbsolute);

添加以下行

mediaPlayerLauncher.Location = MediaLocationType.Install;

注意：

mediaPlayerLauncher.Location = MediaLocationType.Data; // If you open media from isolated storage    
// (or)     
mediaPlayerLauncher.Location = MediaLocationType.Install; // If you open media from application project

Answer 2

您是否曾尝试使用UriKind.Absolute并为其指定文件目标的完整路径？

mediaPlayerLauncher.Media = new Uri(".../.../To_The_Limit_720_230.ismv", UriKind.Absolute);
