JSON介绍
Json是一种轻量数据交互格式，易于阅读，编写，基于ECMAScript 的一个子集,是一种独立语言。为了数据传输方便，传输时，将要传输的对象序列化为Json，效率极高。接收时，通过反序列化转化成对象。与XML语言效果一样。两者可以相互代替。但比XML更简洁，更容易阅读，传输效率更高。
语法规则
- 数据保存在键值对中
- 数据由逗号分隔
- 花括号保存对象
- 方括号保存数组
- 值可以是双引号括起来的字符串、数值(number)、true、false、 null、对象或者数组（array）
1. 使用LitJson进行序列化与反序列化

Console.WriteLine(json);

2. 使用FastJson进行序列化与反序列化
fastJson序列化，反序列化，都只需要一行代码。且运行速度快.
