XML sound's byte form
===

I have a .wav file and i write this byte form to XML. I want to play this song on my form but I am not sure I am correct and it doesn't work.  Str is my file's byte form.

    byte[] soundBytes= Convert.FromBase64String(str);
                       MemoryStream ms = new MemoryStream(soundBytes, 0, soundBytes.Length);
                       ms.Write(soundBytes, 0, soundBytes.Length);
                       SoundPlayer ses = new SoundPlayer(ms);
                       ses.Play();
