class Program

    static void Main(string[] args)
    {
        string json = "{\"name\":\"John\", \"age\":30, \"city\":\"New York\"}";

        // 将JSON转换为JObject
        JObject jObject = JObject.Parse(json);

        // 将JObject转换为XML
        XmlDocument xmlDoc = JsonConvert.DeserializeXmlNode("root", jObject);

        // 输出XML
        string xml = xmlDoc.InnerXml;
        Console.WriteLine(xml);
