高效Json类 操作数据

废话不多说 上代码 :

 也是建立与    Newtonsoft.Json 的基础上，增加对datatime类型的处理,比较方便直观

 

用法:

json.Encode  

json.Decode

 

 

代码见下:

using System;
using System.Collections.Generic;
using System.Text;
using System.Collections;

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using Newtonsoft.Json.Converters;
