支付结果返回页面方法：

支付结果接受：

 if (!string.IsNullOrEmpty(Request["merVAR"]) && Request["merVAR"].ToString().Equals("icbc"))
                {
                    string xml = DecodeBase64(Encoding.Default, Request["notifyData"].ToString());
                   
                    XmlDocument xmldoc = new XmlDocument();
                    xmldoc.LoadXml(xml);
                    string paystate = xmldoc.DocumentElement.SelectSingleNode("/B2CRes/bank/tranStat").InnerText;

                    string orderid= xmldoc.DocumentElement.SelectSingleNode("/B2CRes/orderInfo/subOrderInfoList/subOrderInfo/orderid").InnerText;


                }

///

        /// Base64解密
        ///

        /// 解密采用的编码方式，注意和加密时采用的方式一致
        /// 待解密的密文
        /// 解密后的字符串
        public static string DecodeBase64(Encoding encode, string result)
        {
            string decode = "";
            byte[] bytes = Convert.FromBase64String(result);
            try
            {
                decode = encode.GetString(bytes);
            }
            catch
            {
                decode = result;
            }
            return decode;
        }

注意：项目需要引用ICBCEBANKUTILLib.DLL，该DLL银行都会提供，在这就不上传了。
