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);        }

运行结果
{“result”:1,”user”:{“name”:”zhang”,”password”:123456}}
result=1
name=zhang
psw=123456

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; }    }

操作

static void jsonTest2()        {            Person p1 = new Person();            p1.name = "zhangsan";            p1.age = 23;            string jsonData = JsonMapper.ToJson(p1);            Console.WriteLine("json=" + jsonData);            Person p = JsonMapper.ToObject<Person>(jsonData);            Console.WriteLine("name=" + p.name + "  age=" + p.age);        }

运行结果
json={“name”:”zhangsan”,”age”:23,”adress”:null}
name=zhangsan age=23

将对象和对象内容以键值对的形式进行保存

 static void jsonTest3()        {            Person p1 = new Person();            p1.name = "zhangsan";            p1.age = 23;            //将对象序列化为字符串            JsonData userData = JsonMapper.ToObject(JsonMapper.ToJson(p1));            JsonData jd = new JsonData();            jd["user1"] = new JsonData();            jd["user1"].Add(userData);//以数组的格式保存数据            jd["user2"] = new JsonData();            jd["user2"] = userData;//以对象的格式保存数据            string jsonData = JsonMapper.ToJson(jd);            Console.WriteLine("json=" + jsonData);            //把json数据反序列化为对象            JsonData json = JsonMapper.ToObject(jsonData);            Person p = JsonMapper.ToObject<Person>(json["user2"].ToJson());            Console.WriteLine("name=" + p.name + "  age=" + p.age);            Person pp = JsonMapper.ToObject<Person>(json["user1"][0].ToJson());            Console.WriteLine("name=" + pp.name + "  age=" + pp.age);        }

运行结果：user1以数组的形式保存，user2以对象的形式保存
json={“user1”:[{“name”:”zhangsan”,”age”:23,”adress”:null}],
“user2”:{“name”:”zhangsan”,”age”:23,”adress”:null}}
name=zhangsan age=23
name=zhangsan age=23

将集合数据进行序列化和反序列化

 public static void jsonTest4()        {            Person p1 = new Person();            p1.name = "zhangsan";            p1.age = 23;            Adress adress1 = new Adress();            adress1.province = "HeNan";            adress1.city = "LuoYang";            p1.adress = adress1;            Person p2 = new Person();            p2.name = "lisi";            p2.age = 20;            Adress adress2 = new Adress();            adress2.province = "HeBei";            adress2.city = "HanDan";            p2.adress = adress2;            List<Person> list = new List<Person>();            list.Add(p1);            list.Add(p2);            //生成json数据            string listJson = JsonMapper.ToJson(list);            Console.WriteLine(listJson);            Console.WriteLine("------------------------");            //解析json            List<Person> personJsonList = JsonMapper.ToObject<List<Person>>(listJson);            for (int i = 0; i < personJsonList.Count; i++)            {                Console.WriteLine("name" + personJsonList[i].name);            }        }

运行结果
[{“name”:”zhangsan”,”age”:23,”adress”:{“province”:”HeNan”,”city”:”LuoYang”}},
{“name”:”lisi”,”age”:20,”adress”:{“province”:”HeBei”,”city”:”HanDan”}}]

namezhangsan
