推荐答案

您可以使用 MediaLibrary 访问用户设备上的歌曲、艺术家和专辑.

You can use the MediaLibrary to access the songs, artists and albums on the user's device.

using(MediaLibrary library = new MediaLibrary())
{
     SongCollection songs = library.Songs;
     Song song = songs[0];
     MediaPlayer.Play(song);
}

对于您的第二个问题，您是否复制了插图以及代码和参考资料?除了您下载的示例之外，一些示例包括 this 和 这个.MediaPlayer 并不是特别的复杂的类，它有基本的播放、停止、暂停等方法.第二个示例链接提供了一个音乐管理器，用于演示在使用 MediaPlayer 时如何处理某些事件(例如电话).

For your second problem, did you copy the artwork over as well as the code and references? Some samples, other than the one you've downloaded include this and this. The MediaPlayer isn't a particularly complex class, it has the basic play, stop, pause etc.. methods. The second sample link provides a music manager that demonstrates how to handle certain events (such as a phone call) when using the MediaPlayer.
