If you can't read my code, try converting it here[^]

List<Track> TracksOniTunes = new List<Track>();

foreach (Track item in TracksOniTunes)

for (int countForTrack = countTracks; countForTrack > 0; countForTrack--)
{
    currentTrack = tracks[countTracks] as IITFileOrCDTrack;
    countTracks--;
    TracksOniTunes.Add(new Track(currentTrack.Name, currentTrack.Artist, currentTrack.Album, currentTrack.SampleRate, currentTrack.BitRate));
}

item.SampleRate = 0;

My Problem is that i can't editing some items?

I can not access the objects.

public string Name { get; set; }
public string Artist{ get; set; }
