read and playing file

Why? It is unlikely that a short byte stream will contain anything like a real sound sample.

You can do it: convert the bytes to a stream, and feed that to sound player. But I don't know if it will work with a random short segment of a MP3 file - I suspect not.

using (Stream s = new MemoryStream(bytes))
   {
   System.Media.SoundPlayer myPlayer = new System.Media.SoundPlayer(s);
   myPlayer.Play();
   }
