using taglib# to extract mp3 tags

How would i use taglib to extract the id3 tags of an entire folder of mp3 files, I am currently only able to get it to extract the tag of say genre for one mp3 file at a time.I need to be able to extract the id3 tag from an entire folder of mp3 files.

The mp3 files that match the required genre then need to be copied to a new folder location which i have been able to do for one mp3 file but not multiple.

You need to go through all the files in the directory and check whether each of them has the required genre.

For that, you can use some LINQ:

string genre = "Hip-Hop, Rock"; // Change as required... You can also provide a single genre or even more than 2.
var matchingFiles = Directory.GetFiles(@"Folder\SubFolder", "*.mp3", SearchOption.AllDirectories).Where(x => { var f = TagLib.File.Create(x); return ((TagLib.Id3v2.Tag) f.GetTag(TagTypes.Id3v2)).JoinedGenres == genre; });
foreach (string f in matchingFiles)
{
     System.IO.File.Move(f, Path.Combine(@"D:\NewFolder", new FileInfo(f).Name));
}

I would also like to point out that if the file has multiple genres, you can even set the criteria to select all files which contain that genre:

var matchingFiles = Directory.GetFiles(@"Folder\SubFolder", "*.mp3", SearchOption.AllDirectories).Where(x => { var f = TagLib.File.Create(x); return ((TagLib.Id3v2.Tag) f.GetTag(TagTypes.Id3v2)).Genres.Contains(genre); });

The above would, for example, select files with the following genres, when genre is set to Hip-Hop:

Hip-Hop
Hip-Hop, Rock
Hip-Hop, Trap
Hip-Hop, Rock, Punk, Trap

The above set of genres is obviously not realistic. It's just an example :)
