c# mysql 활용 질문 좀 드려도 될까요?

private void okButton_Click(object sender, EventArgs e)
        {
            MySqlConnection con = new MySqlConnection();
            con.ConnectionString = "Data source=localhost;Database=dstestdb;" + "User Id=root;Password=1111";
            con.Open();
 
            try
            {
                string query = "insert into ds values" + "(" + "\'" + cellPhoneTextBox.Text + "\', " +
                "\'" + korNameTextBox.Text + "\', " +
                "\'" + enNameTextBox.Text + "\', " +
                "\'" + birthDayTextBox.Text + "\', " +
                "\'" + qnetIdTextBox.Text + "\', " +
                "\'" + qnetPassowrdTextBox.Text + "\', " +
                "\'" + subjectComboBox.Text + "\', " +
                "\'" + Data.savePath + "\\\'" + ");";
 
                MySqlCommand command = new MySqlCommand(query, con);
                int ret = command.ExecuteNonQuery();
            } catch(MySqlException mse)
            {
                 MessageBox.Show("저장할 수 없습니다. " + mse.Message.ToString());
                return;
            } finally
            {
                ;
            }
 
            con.Close();
            MessageBox.Show("회원 정보를 저장합니다.");
            this.Close();
            mainForm.getListData();
 
 
 
        }
