C#将XML转换成JSON转换XML

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);

            doc.AppendChild(nRoot);
