创建.XML文件
string xml = @"<?xml version=""1.0"" standalone=""no""?>

                            <root>

                              <person id=""1"">

                              <name>Alan</name>

                              <url>http://www.jb51.net</url>

                              </person>

                              <person id=""2"">

                              <name>Louis</name>

                              <url>http://www.jb51.net</url>

                              </person>

                            </root>";

c#将.xml文件与json对象之间相互转换
namespace DataProvider

{

    public class MarketBarometer : IHttpHandler

    {

        public bool IsReusable

        {

            get

            {

                return false;

            }

        }

        public void ProcessRequest(HttpContext context)

        {

            string path = AppDomain.CurrentDomain.BaseDirectory + "Data.xml";

            XElement data = XElement.Load(path);

            //XML to JSON

            string dataObj = JsonConvert.SerializeXNode(data);

            //JSON to XML

            //XDocument dataDom = JsonConvert.DeserializeXNode(dataObj);

            context.Response.Write(dataObj);

        }
