使用DotNetBarcode制作基本常用条码

核心代码：
        /// <summary>
        /// 打印一维码
        /// </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)
            {
                if (code.Image == null)
                {
                    MessageBox.Show("需要打印的字段中存在空值,条码会出现残缺，请检查是否维护了某些需要打印的字段" + ex.Message + "
 Some Information Need To Be Printed Is null, Please Contact Maintain It");
                }
            }
            
        }
        /// <summary>

        {
