1、利用.NET自身的JavaScriptSerializer

需要添加System.Web.Extensions.dll

添加方法见:

  1. using System;
  2. using System.Collections.Generic;
  3. using System.Linq;
  4. using System.Text;
  5. using System.Web.Script.Serialization;
  6. namespace TestJSON
  7. {
  8.     class CustomData
  9.     {
  10.         public string Input;
  11.         public string Output;
  12.     }
  13.     class Program
  14.     {
  15.         static void Main(string[] args)
  16.         {
  17.             Console.WriteLine("----------------------- Using .Net JavaScriptSerializer api for JSON ------------------------\n");
  18.             CustomData p = new CustomData() { Input = "stone", Output = "gold" };
  19.             JavaScriptSerializer serializer = new JavaScriptSerializer();
  20.             var json = serializer.Serialize(p);
  21.             Console.WriteLine(json);
  22.             var p1 = serializer.Deserialize(json);
  23.             Console.WriteLine(p1.Input + "=>" + p1.Output);
  24.             // 确定指定的 System.Object 实例是否是相同的实例
  25.             Console.WriteLine(ReferenceEquals(p, p1));
  26.             Console.ReadLine();
  27.         }
  28.     }
  29. }

上述结果同时证明了从p到p1是深拷贝。


2、利用Newtonsoft.Json.dll开源库

  8.     class Program
  9.     {
  10.         static void Main(string[] args)
  11.         {
  12.             Console.WriteLine("----------------------- Using NewtonSoftJson api for JSON ------------------------\n");
  13.             //匿名对象解析,uid=0即为整型,若uid="0"则为字符串 
  14.             var tempEntity = new { uid = 0, rid = 0, cmd = 0, commander = 0, target = 0 };
  15.             // 序列化的后发送
  16.             string jsonStr = JsonHelper.SerializeObject(tempEntity);
  17.             // 收到后解析
  18.             tempEntity = JsonHelper.DeserializeAnonymousType("{\"uid\":123,\"rid\":466,\"cmd\":4099,\"commander\":123,\"target\":666}", tempEntity);
  19.             Console.WriteLine(tempEntity.uid);
  20.             Console.ReadLine();
  21.         }
  22.     }
  23. }
