我创建了一个用于保存声音的录音机,我将声音存储到Isolated Storage并使用以下代码来获取路径:

using (IsolatedStorageFile isoFile = IsolatedStorageFile.GetUserStoreForApplication())
{
   if (isoFile.DirectoryExists("/Sound/"))
   {
      var element = (FrameworkElement)sender;
      SoundData data = (SoundData)element.DataContext;

      string name = data.FilePath;
   }
}

我在隔离存储中得到的路径是“/Sound/130215507805691237.wav”。但是如何将声音保存到我的手机作为物理文件?谢谢

像这样使用MediaLibraryExtensions SaveSong方法

MediaLibrary library=new MediaLibrary();
SongMetadata smd=new SongMetadata()
{
    AlbumName = "AlbumName",
    Duration = TimeSpan.FromMinutes(2.50),
    Name = "SongName" 
};
MediaLibraryExtensions.SaveSong(library, new Uri(filePath, UriKind.RelativeOrAbsolute), smd, SaveSongOperation.CopyToLibrary);
