在某个通讯中需要向服务器发送请求xml，格式例子如下：

服务器反馈信息如下：

1、创建xml节点头的实体类、请求实体类、接收实体类

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace XXYYZZ{    public abstract class Header    {        ///         /// 交易号        /// 
        public string Tranno { get; set; }        ///                /// 是否批：Y是 N否        /// 
        public string Batch { get; set; }    }}

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace XXYYZZ{    public class ReqTasklog : Header    {        public List
   
     ReqTasklogBodyList;    }    public class ReqTasklogBody    {        /// 
            ///申请编号        /// 
                public string Appno { get; set; }    }}

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace XXYYZZ{    public class RspTasklog : Header    {        public List
   
     rspTasklogBodyList;    }    public class RspTasklogBody    {        /// 
            ///申请编号        /// 
                public string Appno { get; set; }               /// 
            /// 状态        /// 
        public string Status { get; set; }    }}

2、创建一个生成xml头节点的类XmlHeader

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Xml;namespace XXYYZZ{    public class XmlHeader    {        ///         /// 头节点        /// 
        ///         ///         /// 
           public XmlElement CreateHeaderNode(Header model,XmlDocument doc)        {            XmlDeclaration dec = doc.CreateXmlDeclaration("1.0", "UTF-8", null);            doc.AppendChild(dec);            XmlElement root = doc.CreateElement("ROOT");            doc.AppendChild(root);            //头节点            XmlElement header = doc.CreateElement("HEADER");            root.AppendChild(header);            header.AppendChild(CreateNode(doc, "TRANNO", model.Tranno));                       //内容节点            XmlElement body = doc.CreateElement("BODY");            root.AppendChild(body);            return body;        }        ///         /// 创建节点        /// 
        ///         ///         ///         /// 
           public XmlElement CreateNode(XmlDocument doc, string name, string value)        {            XmlElement element = doc.CreateElement(name);            element.InnerText = value;            return element;        }    }}

3、创建一个将实体转为XML的类ModelToXml，继承XmlHeader

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Xml;namespace XXYYZZ{    public class ModelToXml : XmlHeader    {             ///         /// 请求查询XX状态        /// 
        ///         ///         public void ReqTasklogSave(ReqTasklog model, string fullFileName)        {            XmlDocument doc = new XmlDocument();            XmlElement body = CreateHeaderNode(model, doc);            //是否批量                      string batchValue = model.ReqTasklogBodyList.Count > 1 ? "Y" : "N";            body.AppendChild(CreateNode(doc, "BATCH", batchValue));                                   foreach (ReqTasklogBody reqTasklogBody in model.ReqTasklogBodyList)            {                XmlElement bodyLoanapp = doc.CreateElement("TASKLOG");                body.AppendChild(bodyLoanapp);                bodyLoanapp.AppendChild(CreateNode(doc, "APPNO", reqTasklogBody.Appno));            }                     doc.Save(fullFileName);        }       }}

测试：

private void button2_Click(object sender, EventArgs e)        {            ReqTasklog model = new ReqTasklog()            {                Tranno = "001",                               ReqTasklogBodyList = new List
   
    ()                {                    new ReqTasklogBody()                    {                        Appno = "0000000001"                    },                    new ReqTasklogBody()                    {                        Appno = "0000000002"                    }                }            };            string filename = "ReqTasklog.xml";            ModelToXml createXml = new ModelToXml();            createXml.ReqTasklogSave(model, filename);        }

4、创建一个将xml转为实体的类GetRspTasklog

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Xml;using System.IO;namespace XXYYZZ{    public class XmlToModel    {        public RspTasklog GetRspTasklog(string filepath)        {            RspTasklog model = new RspTasklog();            XmlDocument xDoc = new XmlDocument();            using (StreamReader sr = new StreamReader(filepath, Encoding.UTF8))            {                xDoc.Load(sr);                model.Tranno = GetNodeText(xDoc, "//TRANNO");                               model.Batch = GetNodeText(xDoc, "//BATCH");                model.rspTasklogBodyList = new List
   
    ();                XmlNodeList nodeList = xDoc.SelectNodes("/ROOT/BODY/TASKLOG");                foreach (XmlNode node in nodeList)                {                    RspTasklogBody body = new RspTasklogBody()                    {                         Appno = node["APPNO"].InnerText,                                                 Status = node["STATUS"].InnerText                    };                    model.rspTasklogBodyList.Add(body);                }                          }            return model;        }        private string GetNodeText(XmlDocument xDoc, string xpath)        {            XmlNode xNode = xDoc.SelectSingleNode(xpath);            return (xNode != null) ? xNode.InnerText : "";                     }           }}

测试：

private void button5_Click(object sender, EventArgs e)        {            XmlToModel getxml = new XmlToModel();            RspTasklog model = getxml.GetRspTasklog("RspTasklog.xml");        }
