using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Xml;using Newtonsoft.Json;  namespace JSonConverter{    class Program    {        static void Main(string[] args)        {            string xml = "<Test><Name>Test class</Name><X>100</X><Y>200</Y></Test>";              XmlDocument doc = new XmlDocument();            doc.LoadXml(xml);            string json = Newtonsoft.Json.JsonConvert.SerializeXmlNode(doc);              Console.WriteLine("XML -> JSON: {0}", json);            Console.ReadLine();                      }    }}

　预定义的Json字符串如上

　　同理调用Json.Net类库中的方法

　　XmlDocument doc1 = JsonConvert.DeserializeXmlNode(json);

　　Console.WriteLine(doc1.OuterXml);

XmlDocument doc2 = JsonConvert.DeserializeXmlNode(json1);

　　Console.WriteLine(doc2.OuterXml);

 XmlDictionaryReader reader = JsonReaderWriterFactory.CreateJsonReader(Encoding.UTF8.GetBytes(sJson), XmlDictionaryReaderQuotas.Max);XmlDocument doc = new XmlDocument();doc.Load(reader);收藏一下吧 以后万一用的到我试了一下，json字符串需要把键加"才行如：{Name:"aaa",Value:1}  这里Name和Value是键这样写法转换的时候报错需要写成{"Name":"aaa","Value":1}  这个是第二种方法，这个键加不加"都正常翻译  /// <summary>        /// json字符串转换为Xml对象        /// </summary>        /// <param name="sJson"></param>        /// <returns></returns>        public static XmlDocument Json2Xml(string sJson)        {            //XmlDictionaryReader reader = JsonReaderWriterFactory.CreateJsonReader(Encoding.UTF8.GetBytes(sJson), XmlDictionaryReaderQuotas.Max);            //XmlDocument doc = new XmlDocument();            //doc.Load(reader);            JavaScriptSerializer oSerializer = new JavaScriptSerializer();            Dictionary<string, object> Dic = (Dictionary<string, object>)oSerializer.DeserializeObject(sJson);            XmlDocument doc = new XmlDocument();            XmlDeclaration xmlDec;            xmlDec = doc.CreateXmlDeclaration("1.0", "gb2312", "yes");            doc.InsertBefore(xmlDec, doc.DocumentElement);            XmlElement nRoot = doc.CreateElement("root");            doc.AppendChild(nRoot);            foreach (KeyValuePair<string, object> item in Dic)            {                XmlElement element = doc.CreateElement(item.Key);                KeyValue2Xml(element, item);                nRoot.AppendChild(element);            }            return doc;        }        private static void KeyValue2Xml(XmlElement node, KeyValuePair<string, object> Source)        {            object kValue = http://www.mamicode.com/Source.Value;>
