如何使用Xamarin (Android)获取用户设备中所有音频文件的数据？

using Android.Content;
using Android.Provider;
using Android.Database;

private List<string> GetAudioFiles()
{
    List<string> audioFiles = new List<string>();

    // 查询媒体库中的音频文件
    string[] projection = { MediaStore.Audio.Media.InterfaceConsts.Data };
    string selection = null;
    string[] selectionArgs = null;
    string sortOrder = null;
    ICursor cursor = ContentResolver.Query(MediaStore.Audio.Media.ExternalContentUri, projection, selection, selectionArgs, sortOrder);

    if (cursor != null)
    {
        while (cursor.MoveToNext())
        {
            string audioFilePath = cursor.GetString(cursor.GetColumnIndexOrThrow(MediaStore.Audio.Media.InterfaceConsts.Data));
            audioFiles.Add(audioFilePath);
        }
        cursor.Close();
    }

    return audioFiles;
}

List<string> audioFilesList = GetAudioFiles();
foreach (string audioFilePath in audioFilesList)
{
    // 处理音频文件数据
    // ...
}
