1、利用.NET自身的JavaScriptSerializer
需要添加System.Web.Extensions.dll
添加方法见:
http://blog.chinaunix.net/uid-25498312-id-5675200.html
-
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();
-
}
-
}
-
}
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
点击(此处)折叠或打开
-
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();
-
}
-
}
-
}
