首先理解，json是一种数据格式，而非一种数据类型。json格式的数据类型在c#中为string
开始测试：
使用Newtonsoft.Json包
一：json转object
using Newtonsoft.Json;using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace JsonTest{ ???class Program ???{ ???????static void Main(string[] args) ???????{
???????????//构造json字符串 ???????????var json = "{ ‘people‘:" + ???????????????"[{ ‘firstName‘: ‘Brett‘, ‘lastName‘:‘McLaughlin‘, ‘email‘: ‘aaaa‘ }," + ???????????????"{ ‘firstName‘: ‘Jason‘, ‘lastName‘:‘Hunter‘, ‘email‘: ‘bbbb‘}," + ???????????????"{ ‘firstName‘: ‘Elliotte‘, ‘lastName‘:‘Harold‘, ‘email‘: ‘cccc‘ }]}";
???????????//使用Newtonsoft.Json中的JsonConvert转换json ???????????var jsonObj = JsonConvert.DeserializeObject<PeopleFather>(json); ???????????foreach (People item in jsonObj.people) { ???????????????Console.WriteLine("firstName:"+item.firstName); ???????????????Console.WriteLine("lastName:" + item.lastName); ???????????????Console.WriteLine("email:" + item.email); ???????????????Console.WriteLine("------"); ???????????} ???????????Console.ReadLine(); ???????} ???} ???//构造json要转换的类 ???public class PeopleFather { ??????public List<People> people { get; set; } ???} ???public class People { ???????public string firstName { get; set; } ???????public string lastName { get; set; } ???????public string email { get; set; } ???}}结果：
二：对象类型转json
同样使用Newtonsoft.Json包
static void Main(string[] agrs) ???????{ ??????????????????var people = new People(); ???????????people.firstName = "a"; ???????????people.lastName = "b"; ???????????people.email = "c"; ???????????var json = JsonConvert.SerializeObject(people); ???????????Console.WriteLine(json); ???????????Console.ReadLine(); ???????} public class People { ???????public string firstName { get; set; } ???????public string lastName { get; set; } ???????public string email { get; set; } ???}需要说明的是
JsonConvert.SerializeObjectzai 被多次重载，还提供其它很多功能的支持
j.net 实现json的序列化与反序列化
