Json序列化与反序列化

Posted 2022-03-19 junweitang

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：
