Just wanted to post my example too using NAudio.Lame:

NuGet:

Install-Package NAudio.Lame

Code Snip: Mine obviously returns a byte[] - I have a separate save to disk method b/c I think it makes unit testing easier.

public static byte[] ConvertWavToMp3(byte[] wavFile)
        {

            using(var retMs = new MemoryStream())
            using (var ms = new MemoryStream(wavFile))
            using(var rdr = new WaveFileReader(ms))
            using (var wtr = new LameMP3FileWriter(retMs, rdr.WaveFormat, 128))
            {
                rdr.CopyTo(wtr);
                return retMs.ToArray();
            }


        }
