Looping the list

Question

I have a problem with looping a list of songs. I have a List<String> _songList which contains songs paths (loaded correctly, checked). So I thought that there is an event which will tell me "Ok I stopped playing the song, I'm ready to play the next one". In NAudio it should be StoppedEventArgs added to WaveOutEvent.PlaybackStopped. But in my case it doesn't play another song, neither the same again. Here is my code:

public void Play_List(String _playlistName)
{
    try
    {
        if (_songList.Count > 0)
        {
            if (!_paused)
            {
                _currentList = _playlistName;
                PrimaryOutputStream =
                    new MediaFoundationReader(_songList[_songIndex]);
                VolumeStream = new WaveChannel32(PrimaryOutputStream);
                VolumeStream.PadWithZeroes = false;

                Player.Init(VolumeStream);
                Player.PlaybackStopped +=
                    new EventHandler<StoppedEventArgs>(RepeatMode);
            }
            Player.Play();

            _paused = false;
            _isPlaying = true;
        }
    }
    catch (Exception e)
    {
        System.Windows.MessageBox.Show(e.ToString());
    }
}

public void RepeatMode(object sender, StoppedEventArgs e)
{
    try
    {
        if (_songList.Count > 0 && _currentSong != null)
        {
            _paused = false;
            switch (_repeatMode)
            {
                case 1:     //Repeat one song
                    Play_List(_currentList);
                    break;
                case 2:     //Repeat whole list
                    NextSong();
                    Play_List(_currentList);
                    MessageBox.Show("Changed song");
                    break;
                default:
                    break;
            }
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString());
    }
}

Of course I set _repeatMode to 2 for list and 1 for one song. I was searching the internet for help but found nothing. Anyone?

Answer 1

I do not see anything in your code which sets a value to the _currentSong. Probably, it is coming as null and your code is not getting executed.

if (_songList.Count > 0 && _currentSong != null)
