Question

作者有3个歌曲,这足以确保歌首选法Im的作品将管理超过3个歌曲。

因此,只是想知道它是否可行?

Answer 1

Unfortunately there is no way to add songs to the emulator.
You ll have to use a real device to test this.

Answer 2

实际上,你可以使用这样的手法:

Uri file = new Uri("Assets/Happy.mp3", UriKind.Relative);

//copy file to isolated storage
var myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication();
var fileStream = myIsolatedStorage.CreateFile("someSong.mp3");
var resource = Application.GetResourceStream(file);
int chunkSize = 4096;
byte[] bytes = new byte[chunkSize];
int byteCount;
while ((byteCount = resource.Stream.Read(bytes, 0, chunkSize)) > 0)
{
    fileStream.Write(bytes, 0, byteCount);
}
fileStream.Close();
Microsoft.Xna.Framework.Media.PhoneExtensions.SongMetadata metaData = 
    new Microsoft.Xna.Framework.Media.PhoneExtensions.SongMetadata();
metaData.AlbumName = "Some Album name";
metaData.ArtistName = "Some Artist Name";
metaData.GenreName = "test";
metaData.Name = "someSongName";

var ml = new MediaLibrary();
Uri songUri = new Uri("someSong.mp3", UriKind.RelativeOrAbsolute);
var song = Microsoft.Xna.Framework.Media.PhoneExtensions.MediaLibraryExtensions.SaveSong(ml, songUri, metaData, Microsoft.Xna.Framework.Media.PhoneExtensions.SaveSongOperation.CopyToLibrary);
