C# Json序列化与反序列化

准备工作 

一、新建控制台程序用于测试

二、管理NuGet程序包——搜索<Newtonsoft.json> —— 安装所需程序包

三、引用 using Newtonsoft.Json

开始测试

 创建所用的类

添加数据

序列化数据——JsonConvert.SerializeObject(Object);

DeBug查看：

打看Json可视化工具查看：

 

 控制台输出结果：

 

反序列化

单条数据： object 参数 = JsonConvert.DeserializeObject<object>(json);

 

多条数据：List<object> 参数 = JsonConvert.DeserializeObject<List<object>>(json);

 

结果：

using Newtonsoft.Json;
using System;
using System.Collections.Generic;

namespace Json_Demo
{
    public class Program
    {
        static void Main(string[] args)
        {
            //添加数据
            List<Student> students = new List<Student>
            {
                new Student { ID = 1, Name = "test1", Age = 20, Gender= Gender.男, Grade = Grade.电子商务, Score = new Score {  CShare = 91, Java = 89 , English = 80, Network = 70 } },
                new Student { ID = 2, Name = "test2", Age = 19, Gender= Gender.女, Grade = Grade.网络技术, Score = new Score {  CShare = 84, Java = 77 , English = 94, Network = 86 } },
                new Student { ID = 3, Name = "test3", Age = 22, Gender= Gender.男, Grade = Grade.软件工程, Score = new Score {  CShare = 88, Java = 96 , English = 93, Network = 90 } }
            };

            Console.WriteLine("输入原数据：");
            foreach (var item in students)
            {

                    item.Score.CShare + "\t" + item.Score.Java + "\t" + item.Score.English + "\t" + item.Score.Network);
            }

            Console.WriteLine("序列化数据：");
            var jsonStr = JsonConvert.SerializeObject(students);

            Console.WriteLine(jsonStr);

            Console.WriteLine("反序列化数据：");

            List<Student> jsonToObject = JsonConvert.DeserializeObject<List<Student>>(jsonStr);

            foreach (var item in jsonToObject)
            {

            }

            Console.ReadKey();
        }
