[大数据]NewtonJson 的一个例子

person 类 代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace NewTonJSONTest
{
    class Person
    {
    public string Name { get; set; }
    public int Age { get; set; }
     public string[] Mobiles { get; set; }
    }
}

一个控制台程序的默认的类，也是main所在的类 Program 代码如下：

using System;
using System.Collections.Generic;
using Newtonsoft.Json;//
using Newtonsoft.Json.Linq;//

namespace NewTonJSONTest
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");
            List<Person> person0;
            List<Person> person = new List<Person>(){
               new Person() {Name = "China Mobile", Age = 30, Mobiles = new string[] {"13800138000","10086"}},
               new Person() {Name = "China Telecom", Age = 60, Mobiles = new string[] {"10000","189"}},
               new Person() {Name = "China Unicom", Age = 90, Mobiles = new string[] {"10010"}}
            };
            // 序列化为JSON字串
            string str_json = JsonConvert.SerializeObject(person);
            Console.WriteLine(str_json);
            Console.WriteLine("序列化完成了，序列化了对象为一个json字符串");


            // 反序列化为Person列表对象 ,反序列化是?str_json字符串 序列化为一个对象
            person0 = JsonConvert.DeserializeObject<List<Person>>(str_json);
            foreach (var temp in person0)
            {
                Console.WriteLine(temp.Age + " " + temp.Name + " " + temp.Mobiles + "\n");
            }

            //  JObject oPostData = JsonConvert.DeserializeObject<JObject>(str_json); //@@

            //  oPostData.GetValue("Channel").ToString();//@@
        }
    }
}

运行结果 如下图：

Hello World!
[{"Name":"China Mobile","Age":30,"Mobiles":["13800138000","10086"]},{"Name":"China Telecom","Age":60,"Mobiles":["10000","189"]},{"Name":"China Unicom","Age":90,"Mobiles":["10010"]}]
序列化完成了，序列化了对象为一个json字符串
30 China Mobile System.String[]

60 China Telecom System.String[]

90 China Unicom System.String[]
