Json学习笔记

Json基本语法：

json数据结构：

代码事例：

//program.cs
using LitJson;
using System;
using System.Collections.Generic;
using System.IO;

namespace JsonStudy
{
    class Program
    {
        static void Main(string[] args)
        {
            List skillList = JsonMapper.ToObject>(File.ReadAllText("SkillInfo.txt"));
            foreach (var tmp in skillList)
            {
                Console.WriteLine(tmp);
            }
        }
    }
}

//SkillInfo.txt
[
	{"id":1,"name":"龙闪","level":1},
	{"id":2,"name":"居合","level":1},
	{"id":3,"name":"一字斩","level":1}
]

//Skill.cs
using System;
using System.Collections.Generic;
using System.Text;

namespace JsonStudy
{
    class Skill
    {
        public int id;
        public string name;
        public int level;

        public Skill(int id, string name, int level)
        {
            this.id = id;
            this.name = name;
            this.level = level;
        }

        public override string ToString()
        {
            return string.Format("id:{0},name:{1},level:{2}", id, name, level);
        }
    }
}

注意Skill类要和相应的txt文件每个元素保持一致（文件名等）

实例2：

//Program.cs
using LitJson;
using System;
using System.Collections.Generic;
using System.IO;

namespace JsonStudy
{
    class Program
    {
        static void Main(string[] args)
        {
            Player player = JsonMapper.ToObject(File.ReadAllText("PlayerInfo.txt"));
            Console.WriteLine(player);
            foreach (var tmp in player.skillList)
            {
                Console.WriteLine(tmp);
            }
        }
    }
}

//PlayerInfo.txt
{
	"name":"tqt",
	"level":1,
	"skillList":
	[
		{"id":1,"name":"龙闪","level":1},
		{"id":2,"name":"居合","level":1},
		{"id":3,"name":"一字斩","level":1}
	]
}

//Player.cs
using System;
using System.Collections.Generic;
using System.Text;

namespace JsonStudy
{
    class Player
    {
        public string name;
        public int level;
        public List skillList;

        public override string ToString()
        {
            return string.Format("name:{0},level:{1}", name, level);
        }
    }
}

也可以将我们构造的对象转化成json字符串：

//Program.cs
using LitJson;
using System;
using System.Collections.Generic;
using System.IO;

namespace JsonStudy
{
    class Program
    {
        static void Main(string[] args)
        {
            Player player = new Player();
            player.name = "tqt";
            player.level = 1;
            Skill skill1 = new Skill(1, "龙闪", 1);
            Skill skill2 = new Skill(2, "居和", 1);
            player.skillList = new List();
            player.skillList.Add(skill1);
            player.skillList.Add(skill2);
            string jsonString = JsonMapper.ToJson(player);
            Console.WriteLine(jsonString);
        }
    }
}
