使用DotNetBarcode製做基本經常使用條碼

核心代碼：
        /// <summary>
        /// 打印一維碼
        /// </summary>
        /// <param name="codeText"></param>
        /// <param name="g"></param>
        /// <param name="pointX"></param>
        /// <param name="pointY"></param>
        /// <param name="width"></param>
        /// <param name="height"></param>
        public void PrintBarcode(string codeText, Graphics g, int pointX, int pointY, int width, int height)
        {
            C1BarCode code = new C1BarCode();
            code.CodeType = CodeTypeEnum.Code128;
            code.Text = codeText;
            try
            {
                g.DrawImage(code.Image, pointX, pointY, width, height);

            catch (Exception ex)
            {

                {
                    MessageBox.Show("須要打印的字段中存在空值,條碼會出現殘缺，請檢查是否維護了某些須要打印的字段" + ex.Message + "\n Some Information Need To Be Printed Is null, Please Contact Maintain It");
