            Bitmap img = qrCodeEncoder.Encode(qrCodeContent, Encoding.UTF8);//指定utf-8编码， 支持中文

            return img;

        }

        /// <summary>

        /// 解析二维码

        /// </summary>

        /// <param name="bitmap">要解析的二维码位图</param>

        /// <returns>解析后的字符串</returns>

        public static string QRCodeDecoderUtil(Bitmap bitmap)

        {

            QRCodeDecoder decoder = new QRCodeDecoder();
