            if (_mediaFile == null)
                return;
            dir_local = _mediaFile.Path;
            file_name = Path.GetFileName(dir_local);
            _ = DisplayAlert("File Info", file_name, "OK");

            
            Stream fs = _mediaFile.GetStream();
            BinaryReader br = new BinaryReader(fs);
            byte[] bytes = br.ReadBytes((Int32)fs.Length);


            //MYSQL Connection
            MySqlConnection zeeconn = new MySqlConnection(Properties.Resources.db_con);
                       
            MySqlCommand cmd = new MySqlCommand("insert into tblTest (user,pass) values (@user,@pass)", zeeconn);
            

            var user = new MySqlParameter("@user", MySqlDbType.LongBlob, bytes.Length);
            var pass = new MySqlParameter("@pass", MySqlDbType.VarChar, 50);
            
            user.Value = bytes;
            pass.Value = "zero";

            cmd.Parameters.Add(user);
            cmd.Parameters.Add(pass);

            cmd.ExecuteNonQueryAsync();
            zeeconn.Close();
