C# litJson 使用方法

本文主要是介绍C# litJson 使用方法，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

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jsonList<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”}}]
