1、利用.NET自身的JavaScriptSerializer
需要添加System.Web.Extensions.dll
添加方法见:

- using System;
- using System.Collections.Generic;
- using System.Linq;
- using System.Text;
- using System.Web.Script.Serialization;
- namespace TestJSON
- {
- class CustomData
- {
- public string Input;
- public string Output;
- }
- class Program
- {
- static void Main(string[] args)
- {
- Console.WriteLine("----------------------- Using .Net JavaScriptSerializer api for JSON ------------------------\n");
- CustomData p = new CustomData() { Input = "stone", Output = "gold" };
- JavaScriptSerializer serializer = new JavaScriptSerializer();
- var json = serializer.Serialize(p);
- Console.WriteLine(json);
- var p1 = serializer.Deserialize(json);
- Console.WriteLine(p1.Input + "=>" + p1.Output);
- // 确定指定的 System.Object 实例是否是相同的实例
- Console.WriteLine(ReferenceEquals(p, p1));
- Console.ReadLine();
- }
- }
- }
2、利用Newtonsoft.Json.dll开源库

- using System;
- using System.Collections.Generic;
- using System.Linq;
- using System.Text;
- using System.Web.Script.Serialization;
- namespace TestJSON
- {
- class Program
- {
- static void Main(string[] args)
- {
- Console.WriteLine("----------------------- Using NewtonSoftJson api for JSON ------------------------\n");
- //匿名对象解析,uid=0即为整型,若uid="0"则为字符串
- var tempEntity = new { uid = 0, rid = 0, cmd = 0, commander = 0, target = 0 };
- // 序列化的后发送
- string jsonStr = JsonHelper.SerializeObject(tempEntity);
- // 收到后解析
- tempEntity = JsonHelper.DeserializeAnonymousType("{\"uid\":123,\"rid\":466,\"cmd\":4099,\"commander\":123,\"target\":666}", tempEntity);
- Console.WriteLine(tempEntity.uid);
- Console.ReadLine();
- }
- }
- }
- /* JasonHelper.cs文件: */
- using System;
- using System.Collections.Generic;
- using System.Linq;
- using System.Text;
- using System.IO;
- using Newtonsoft.Json;
-
- namespace TestJSON

- T t = o as T;
- return t;

- List list = o as List;
- return list;

- public static T DeserializeAnonymousType(string json, T anonymousTypeObject)
- {
- T t = JsonConvert.DeserializeAnonymousType(json, anonymousTypeObject);
- return t;
- }
- }
