Как я должен воспроизводить mp3-файл в соответствии с выбором строки gridview в ASP.NET с#

GridViewRow gvRow = (GridViewRow)(sender as Control).Parent.Parent;
        int index = gvRow.RowIndex;
        int TID = Convert.ToInt32(gvTrainStatus.DataKeys[index]["TID"]);
        Session["TID"] = TID;

        //if (TID = Session["TID"])
        //{
            DataTable dt = new DataTable();
            SqlConnection con = new SqlConnection(CS);
            con.Open();
            SqlCommand cmd = new SqlCommand("SPShowData", con);
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.AddWithValue("@TID", Session["TID"]);
            SqlDataAdapter sqlDa = new SqlDataAdapter(cmd);
            sqlDa.Fill(dt);
            if (dt.Rows.Count > 0)
            {



            //SoundPlayer sd = new SoundPlayer();
            //lblTrainNo.Text = dt.Rows[0]["TrainNo"].ToString();
      

            SoundPlayer player = new SoundPlayer();
            player.SoundLocation = AppDomain.CurrentDomain.BaseDirectory + "Sound/0.mp3";
            player.Play();
