以下是我在MSDN论坛上找到的代码:
Dim file As New Uri("Assets/someSong.mp3", UriKind.Relative)
Dim myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication()
Dim fileStream As IsolatedStorageFileStream = myIsolatedStorage.CreateFile("someSong.mp3")
Dim resource = Application.GetResourceStream(file)
Dim chunkSize As Integer = 4096
Dim bytes As Byte() = New Byte(chunkSize - 1) {}
Dim byteCount As Integer
While resource.Stream.Read(bytes, 0, chunkSize) > 0
byteCount = resource.Stream.Read(bytes, 0, chunkSize)
fileStream.Write(bytes, 0, byteCount)
End While
fileStream.Close()
Dim metaData As New Microsoft.Xna.Framework.Media.PhoneExtensions.SongMetadata()
metaData.AlbumName = "Some Album name"
metaData.ArtistName = "Some Artist Name"
metaData.GenreName = "test"
metaData.Name = "someSongName"
metaData.Duration = TimeSpan.FromSeconds(185)
Dim ml = New MediaLibrary()
Dim songUri As New Uri("someSong.mp3", UriKind.RelativeOrAbsolute)
Dim song = Microsoft.Xna.Framework.Media.PhoneExtensions.MediaLibraryExtensions.SaveSong(ml, songUri, metaData, Microsoft.Xna.Framework.Media.PhoneExtensions.SaveSongOperation.CopyToLibrary)
所以我可以将歌曲加载到我的手机歌曲中心(Lumia 920),但是当我点击非歌曲时它会给出错误:c00d36c4。在保存期间,流似乎被破坏了。
我正在尝试保存的歌曲在应用程序项目中,包含构建操作“内容”和“不要复制”。
在WP Emulator上也是如此,即使我使用另一个mp3文件也是如此。
我找不到任何关于SaveSong方法的官方文档,你能帮助我吗?
答案 0 :(得分:0)
解决了这个问题。它无法正确复制整个流。我切换到[Stream].CopyTo
方法,然后工作。
