aspx.cs 文件中如何获取Webservice读出的数据方式

 protected void BindGrid()
        {
            WebSystem.ServiceReference1.ncwebserviceSoapClient ncdata = new ServiceReference1.ncwebserviceSoapClient();
            service = ncdata.NClist(StartDate, EndDate);//关联服务的方法

            List<RcscbbDonation> rcscbbList = new List<RcscbbDonation>();
            if (!string.IsNullOrEmpty(service))
            {
                XmlDocument document = new XmlDocument();
                document.LoadXml(service);
                XmlNodeList donNodeList = document.SelectNodes("Donationlist")[0].ChildNodes;//获取XML节点
                foreach (XmlNode item in donNodeList)
                {                 
                    RcscbbDonation rcscbbDonation = new RcscbbDonation();
                    XmlNodeList InforList = item.ChildNodes;
                    foreach (XmlNode infor in InforList)
                    {
                        switch (infor.Name)
                        {
                            case "DonorName":

                                break;

                        }
                    }
                }
            }
        }
