json转化为xml

   public static string JsonToXml(string strJson)
   {
      string Xml = "";
      XmlDictionaryReader reader = JsonReaderWriterFactory.CreateJsonReader(Encoding.UTF8.GetBytes(strJson), XmlDictionaryReaderQuotas.Max);
      XmlDocument doc = new XmlDocument();
      doc.Load(reader);
      Xml = doc.InnerXml;
      return Xml;
   }
