JsonAbout:

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.IO;using System.Web.Script.Serialization;using System.Runtime.Serialization.Json;

namespace ConsoleApplicationTest{    public class JsonAbout    {        public static T Json2ModelJS<T>(string JsonStr)        {            JavaScriptSerializer jss = new JavaScriptSerializer();            T userJson = jss.Deserialize<T>(JsonStr);            return userJson;        }

        public static string Model2JsonJS<T>(T model)        {            JavaScriptSerializer jss = new JavaScriptSerializer();            string userJson = jss.Serialize(model);            return userJson;        }

        public static T Json2Model<T>(string jsonString)        {            using (var ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString)))            {                return (T)new DataContractJsonSerializer(typeof(T)).ReadObject(ms);            }        }

        public static string Model2Json<T>(T jsonObject)        {            using (var ms = new MemoryStream())            {                new DataContractJsonSerializer(typeof(T)).WriteObject(ms, jsonObject);                return Encoding.UTF8.GetString(ms.ToArray());            }        }    }}

　　测试类：

public class JsonModelDemo    {        public void Show()        {            string jsonA = "{\"IDA\":1,\"NameA\":\"A\",\"B\":{\"IDB\":2,\"NameB\":\"B\"}}";            string jsonB = "{\"Msg\":\"Test\",\"Data\":{\"IDA\":1,\"NameA\":\"A\",\"B\":[{\"IDB\":2,\"NameB\":\"B1\"},{\"IDB\":3,\"NameB\":\"B2\"}]}}";            Console.WriteLine("DataContractJsonSerializer:");            A a1 = JsonAbout.Json2Model<A>(jsonA);            B b1 = JsonAbout.Json2Model<B>(jsonA);            A a2 = JsonAbout.Json2Model<A>(jsonB);            B b2 = JsonAbout.Json2Model<B>(jsonB);            Output(a1);            Output(b1);            Output(a2);            Output(b2);

            Console.WriteLine("JavaScriptSerializer:");            A a3 = JsonAbout.Json2ModelJS<A>(jsonA);            B b3 = JsonAbout.Json2ModelJS<B>(jsonA);            A a4 = JsonAbout.Json2ModelJS<A>(jsonB);            B b4 = JsonAbout.Json2ModelJS<B>(jsonB);            Output(a3);            Output(b3);            Output(a4);            Output(b4);                  }

        private void Output(A a)        {            Console.WriteLine("IDA:"+a.IDA + ", NameA:" + a.NameA);            if (a.b != null)            {                Console.WriteLine("B:"+a.b.IDB+","+a.b.NameB);            }        }        private void Output(B b)        {            Console.WriteLine("IDB:" + b.IDB + ", NameB:" + b.NameB);        }    }    public class A    {        public int IDA { get; set; }

        public string NameA { get; set; }

        public B b { get; set; }    }

    public class B    {        public int IDB { get; set; }

        public string NameB { get; set; }    }

　　输出：

DataContractJsonSerializer:IDA:1, NameA:AIDB:0, NameB:IDA:0, NameA:IDB:0, NameB:JavaScriptSerializer:IDA:1, NameA:AB:2,BIDB:0, NameB:IDA:0, NameA:IDB:0, NameB:

　　结论：JavaScriptSerializer可以识别关联的实体，其他的待验证。
