CSharp-Json的序列化与反序列化

一言加载中...

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

var SkillList = new List<SkillBean>();
SkillBean skill1 = new SkillBean { id = 101, name = "落叶飞花", damage = 500 };
SkillBean skill2 = new SkillBean { id = 102, name = "暗度陈仓", damage = 304 };
SkillBean skill3 = new SkillBean { id = 103, name = "万丈光芒", damage = 302 };
SkillBean skill4 = new SkillBean { id = 104, name = "十方皆杀", damage = 405 };
SkillBean skill5 = new SkillBean { id = 105, name = "银光落刃", damage = 220 };
SkillBean skill6 = new SkillBean { id = 106, name = "幻影剑舞", damage = 690 };
SkillBean skill7 = new SkillBean { id = 107, name = "狂龙紫电", damage = 666 };

SkillList.Add(skill1);
SkillList.Add(skill2);
SkillList.Add(skill3);
SkillList.Add(skill4);
SkillList.Add(skill5);
SkillList.Add(skill6);
SkillList.Add(skill7);

string json = JsonMapper.ToJson(SkillList);
Console.WriteLine(json);

输出结果(汉字自动转化为Unicode)：

string json = File.ReadAllText("SkillInfo.json");
var list = JsonMapper.ToObject<SkillBeanList>(json).SkillList;

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.

序列化

string json = fastJSON.JSON.ToJSON(SkillList);

}
