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"))

xmldoc.LoadXml(xml);
string paystate = xmldoc.DocumentElement.SelectSingleNode("/B2CRes/bank/tranStat").InnerText;
string orderid= xmldoc.DocumentElement.SelectSingleNode("/B2CRes/orderInfo/subOrderInfoList/subOrderInfo/orderid").InnerText;
}

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。
