Json字符串關於做web運用的應當很熟習，其其實許多要求我們前往的都是Json字符串。那關於C#代碼若何處置Json字符串呢，.Net封裝了一個類叫做JavaScriptSerializer[MSDN Library 鏈接http://msdn.microsoft.com/en-us/library/ee191864(v=vs.110).aspx]；這個類供給了一個辦法。

上面這個是我在快遞100往抓取的一個光滑油滑的快遞信息。關於我們有效的信息是快遞時光，快遞狀態。那我該若何來做。　

{"message":"ok","nu":"9356359685","ischeck":"1","com":"yuantong","status":"200","condition":"F00","state":"3","data":[{"time":"2014-09-01 21:19:06","context":"甘肅省武威市公司已簽收 ","ftime":"2014-09-01 21:19:06"},{"time":"2014-09-01 09:09:28","context":"甘肅省武威市公司派件中 ","ftime":"2014-09-01 09:09:28"},{"time":"2014-09-01 09:06:27","context":"甘肅省武威市公司已支出 ","ftime":"2014-09-01 09:06:27"},{"time":"2014-08-31 19:53:47","context":"甘肅省蘭州市公司已收回 ","ftime":"2014-08-31 19:53:47"},{"time":"2014-08-31 19:17:41","context":"甘肅省蘭州市公司已支出 ","ftime":"2014-08-31 19:17:41"},{"time":"2014-08-28 23:44:26","context":"廣東省深圳市橫崗公司已打包 ","ftime":"2014-08-28 23:44:26"},{"time":"2014-08-28 23:19:12","context":"廣東省深圳市橫崗公司已收件 ","ftime":"2014-08-28 23:19:12"},{"time":"2014-08-28 21:55:35","context":"廣東省深圳市橫崗公司已收件 ","ftime":"2014-08-28 21:55:35"}]}

1. 起首剖析Json字符串構造. Json{ message,nu,isCheck,Data{time,context,ftime}};我們先界說一個類，取名為PostalDeliveryModel，類名的構造須要與Json構造對應，稱號須要堅持一樣[疏忽年夜小寫],其次對應的字段說會主動轉換類型的，類型假如不相符會拋出異常

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace TestJson
{
    public class PostalDeliveryModel
    {
        private string message = string.Empty;
        private string nu = string.Empty;
        private List<SingalData> data = new List<SingalData>();
        // Puclic的名字須要與Json字符串雷同,然則疏忽年夜小寫
        public string Message
        {
            get { return this.message; }
            set { this.message = value; }
        }
        public string Nu
        {
            get { return this.nu; }
            set { this.nu = value; }
        }
        public List<SingalData> Data
        {
            get { return this.data; }
            set { this.data = value; }
        }
    }
    public class SingalData
    {
        private DateTime time = System.DateTime.Now;
        private string context = string.Empty;
        private DateTime ftime = System.DateTime.Now;
        public DateTime Time
        {
            get { return this.time; }
            set { this.time = value; }
        }
        public DateTime FTime
        {
            get { return this.ftime; }
            set { this.ftime = value; }
        }
        public string Context
        {
            get { return this.context; }
            set { this.context = value; }
        }
    }
}

2.對象甚麼好後只須要挪用辦法便可:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
using System.Web.Script.Serialization; // 此定名空間對應的框架是 System.Web.Extensions
namespace TestJson
{
    public class Program
    {
        public static void Main(string[] args)
        {
            string jsonStr = new StreamReader("JsonData.txt").ReadToEnd();
            PostalDeliveryModel mode = new JavaScriptSerializer().Deserialize<PostalDeliveryModel>(jsonStr);
            Console.ReadKey();
        }
    }
}
