Newtonsoft.Json是一个开源的C#操作json的项目，应用起来非常简单。其github地址;

下面的代码演示了如何应用Newtonsoft.Json序列号和反序列化。

using Newtonsoft.Json;

using System;

using System.Collections.Generic;

namespace JsonNetDemo

{

    class Program

    {

        static void Main(string[] args)

        {

            List<Project> pList = new List<Project>();

            Project p = new Project();

            p.TestSystemList = new List<TestSystem>();

            p.entrustCellphone = "12";

            p.entrustName = "12";

            p.entrustUnit = "12";

            p.goodsModel = "12";

            p.pid = 34199;

            p.productionCellphone = "12";

            TestSystem t = new TestSystem();

            t.eid = 78611;

            t.name = "5.8G无线局域网(移动终端)";

            p.TestSystemList.Add(t);

            pList.Add(p);

            var json = JsonConvert.SerializeObject(pList);

            Console.WriteLine(json);

            Console.Read();

            string s = "[{\"productionCellphone\":\"12\",\"entrustCellphone\":\"12\",\"entrustUnit\":\"12\",\"pid\":34199,\"goodsModel\":\"12\",\"entrustName\":\"12\",\"TestSystemList\":[{\"eid\":78611,\"name\":\"5.8G无线局域网(移动终端)\"}]}]";

            var ret = JsonConvert.DeserializeObject<List<Project>>(s);

            Console.WriteLine(ret.Count);

            Console.Read();

        }

    }

    class Project

    {

        public string productionCellphone { get; set; }

        public string entrustCellphone { get; set; }

        public string entrustUnit { get; set; }

        public long pid { get; set; }

        public string goodsModel { get; set; }

        public string entrustName { get; set; }

        public List<TestSystem> TestSystemList { get; set; }

    }

    class TestSystem

    {

        public long eid { get; set; }

        public string name { get; set; }

    }

}
