Also may this code serve someone! I have a realize that this is the easiest way just like @Henk said:

using (SqlDataAdapter da = new SqlDataAdapter())
                    {
                        DataTable dt = new DataTable();
                        cmd.CommandType = CommandType.Text;
                        cmd.Connection = con;
                        da.SelectCommand = cmd;
                        da.Fill(dt);
                        dt.Columns[0].ColumnName = "Item NO";
                        dt.Columns[1].ColumnName = "LocalCode";                       
                        dt.Columns[2].ColumnName = "Currency";
                        dt.Columns[3].ColumnName = "Menu Flag";
                        dt.Columns[4].ColumnName = "Item Class";
                        dt.Columns[4].ColumnName = "Dress Sort";
                        return dt;
                    }
