View/edit ID3 data for MP3 files

Question

Thirding TagLib Sharp.

TagLib.File f = TagLib.File.Create(path);
f.Tag.Album = "New Album Title";
f.Save();

TagLib Sharp is pretty popular.

As a side note, if you wanted to take a quick and dirty peek at doing it yourself.. here is a C# snippet I found to read an mp3's tag info.

class MusicID3Tag

{

    public byte[] TAGID = new byte[3];      //  3
    public byte[] Title = new byte[30];     //  30
    public byte[] Artist = new byte[30];    //  30 
    public byte[] Album = new byte[30];     //  30 
    public byte[] Year = new byte[4];       //  4 
    public byte[] Comment = new byte[30];   //  30 
    public byte[] Genre = new byte[1];      //  1

}

string filePath = @"C:\Documents and Settings\All Users\Documents\My Music\Sample Music\041105.mp3";

        using (FileStream fs = File.OpenRead(filePath))
        {
            if (fs.Length >= 128)
            {
                MusicID3Tag tag = new MusicID3Tag();
                fs.Seek(-128, SeekOrigin.End);
                fs.Read(tag.TAGID, 0, tag.TAGID.Length);
                fs.Read(tag.Title, 0, tag.Title.Length);
                fs.Read(tag.Artist, 0, tag.Artist.Length);
                fs.Read(tag.Album, 0, tag.Album.Length);
                fs.Read(tag.Year, 0, tag.Year.Length);
                fs.Read(tag.Comment, 0, tag.Comment.Length);
                fs.Read(tag.Genre, 0, tag.Genre.Length);
                string theTAGID = Encoding.Default.GetString(tag.TAGID);

                if (theTAGID.Equals("TAG"))
                {
                    string Title = Encoding.Default.GetString(tag.Title);
                    string Artist = Encoding.Default.GetString(tag.Artist);
                    string Album = Encoding.Default.GetString(tag.Album);
                    string Year = Encoding.Default.GetString(tag.Year);
                    string Comment = Encoding.Default.GetString(tag.Comment);
                    string Genre = Encoding.Default.GetString(tag.Genre);

                    Console.WriteLine(Title);
                    Console.WriteLine(Artist);
                    Console.WriteLine(Album);
                    Console.WriteLine(Year);
                    Console.WriteLine(Comment);
                    Console.WriteLine(Genre);
                    Console.WriteLine();
                }
            }
        }

UltraID3Lib...

Be aware that UltraID3Lib is no longer officially available, and thus no longer maintained. See comments below for the link to a Github project that includes this library

//using HundredMilesSoftware.UltraID3Lib;
UltraID3 u = new UltraID3();
u.Read(@"C:\mp3\song.mp3");
//view
Console.WriteLine(u.Artist);
//edit
u.Artist = "New Artist";
u.Write();

TagLib Sharp has support for reading ID3 tags.

I wrapped mp3 decoder library and made it available for .net developers. You can find it here:

http://sourceforge.net/projects/mpg123net/

Included are the samples to convert mp3 file to PCM, and read ID3 tags.

ID3.NET implemented ID3v1.x and ID3v2.3 and supports read/write operations on the ID3 section in MP3 files. There's also a NuGet package available.
