1.先创建一个抽象类WildAnimal,再创建一个派生类Panda,最后创建一个含有抽象类集合的PandaInfo类.

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace JSONDemo{    public abstract class WildAnimal    {        public string Name { get; set; }    }}

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace JSONDemo{    public class Panda : WildAnimal    {        public string Food { get; set; }    }}

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace JSONDemo{    public class PandaInfo    {        public int Lifetime { get; set; }        public IList<WildAnimal> WildAnimal { get; set; }    }}

2.序列化与反序列化

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Data;using GongHuiNewtonsoft.Json;namespace JSONDemo{    class Program    {        static void Main(string[] args)        {            PandaInfo info = new PandaInfo()            {                Lifetime = 25,                WildAnimal = new List<WildAnimal>                {                    new Panda                    {                        Name="Meimei",                        Food="bamboo"                    }                }            };            Console.WriteLine("----------序列化包含声明类型与.NET类型------------");            string all = JsonConvert.SerializeObject(info, Formatting.Indented, new JsonSerializerSettings            {                TypeNameHandling = TypeNameHandling.All            });            Console.WriteLine(all);            Console.WriteLine("--------------序列化包含.NET类型------------------");            string auto = JsonConvert.SerializeObject(info, Formatting.Indented, new JsonSerializerSettings            {                TypeNameHandling = TypeNameHandling.Auto            });            Console.WriteLine(auto);            Console.WriteLine("--------------反序列化包含.NET类型----------------");            PandaInfo info2 = JsonConvert.DeserializeObject<PandaInfo>(auto, new JsonSerializerSettings            {                TypeNameHandling = TypeNameHandling.Auto            });            Console.WriteLine(info2.Lifetime);            Panda p = info2.WildAnimal[0] as Panda;            Console.WriteLine(p.Food);            Console.WriteLine(p.Name);        }    }}

3.运行的结果
