C# 调用litJson 方法

对一般数据进行序列化和反序列化操作

---

 static void jsonTest() {            //            JsonData jd = new JsonData();            jd["result"] = 1;            jd["user"] = new JsonData();//**新添加一层关系时，需要再次 new** JsonData（）            jd["user"]["name"] = "zhang";            jd["user"]["password"] = 123456;            string jsonData = JsonMapper.ToJson(jd);            Console.WriteLine(jsonData);            //            JsonData deJson=JsonMapper.ToObject(jsonData);            int result = int.Parse(deJson["result"].ToJson());            string name = deJson["user"]["name"].ToString();            int psw = int.Parse(deJson["user"]["password"].ToString());            Console.WriteLine( "result="+result);            Console.WriteLine("name="+name);            Console.WriteLine("psw="+psw);        }

对数据对象进行序列化和反序列化操作

---

创建对象

  class Adress    {        public string province { set; get; }        public string city { set; get; }    }    class Person    {        public string name { set; get; }        public int age { set; get; }        public Adress adress { set; get; }    }
