JSON 通过强类型或者匿名对象 序列化和反序列化 对象和集合
using Newtonsoft.Json; using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace JSONSerializeDemo { class Program { static void Main(string[] args) { // 簡單的將 對象 序列化成 字符串 Student s = new Student("張三", "男人", 9); //Student s = new Student(); //s.name = "張三"; //s.sex = "男人"; //s.age = 29; string sj = JsonConvert.SerializeObject(s); // "{\"name\":\"張三\",\"sex\":\"男人\",\"age\":9}" // 將JSON字符串反序列化成对象 // 1.指定反序列化的对象 //object o = JsonConvert.DeserializeObject(sj, typeof(Student)); //Student s2 = o as Student; // "張三", "男人", 9 //2.反序列化使用匿名对象 //var Stutemp = new { // name = "", // sex = "", // age = 0 //}; //var s2 = JsonConvert.DeserializeAnonymousType(sj, Stutemp); //3.序列化 对象集合 List<Student> list = new List<Student> { new Student("張三", "男人", 9), new Student("李四", "男人", 25), new Student("小李", "女人", 35) }; string slist = JsonConvert.SerializeObject(list);//"[{\"name\":\"張三\",\"sex\":\"男人\",\"age\":9},{\"name\":\"李四\",\"sex\":\"男人\",\"age\":25},{\"name\":\"小李\",\"sex\":\"女人\",\"age\":35}]" //4,指定对象反序列化集合 //List<Student> slist2=JsonConvert.DeserializeObject<List<Student>>(slist); //5.指定匿名对象反序列化集合 var Stutemp = new { name = "", sex = "", age = 0 }; var listtemp = Enumerable.Repeat(Stutemp, 3);// 生成匿名集合对象 var listo=JsonConvert.DeserializeAnonymousType(slist, listtemp); foreach(var s2 in listo) { Console.WriteLine(s2.name + " " + s2.sex + " " + s2.age); } //Console.WriteLine(s2.name +" "+s2.sex+" "+s2.age); Console.ReadKey(); } } public class Student { public Student() { } public Student(string _name,string _sex,int _age) { name = _name; sex = _sex; age = _age; } public string name; public string sex; public int age; public override string ToString() { return name + " " + sex + " " + age; } } }
