json2xml

　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
