方式一
第一步:使用前，需下載:Newtonsoft.Json.dll
沒有的，請到我百度雲盤下載
鏈接：https://pan.baidu.com/s/1JBkee4qhtW7XOyYFiGOL2Q
提取碼：b5uq
第二步：引入命名空間：using Newtonsoft.Json;
第三步：封裝一個函數，方便以后使用
待解析JSON數組
函數：
public static Newtonsoft.Json.Linq.JArray GetToJsonList(string json) { Newtonsoft.Json.Linq.JArray jsonArr = (Newtonsoft.Json.Linq.JArray)JsonConvert.DeserializeObject(json); return jsonArr; }
實現：
搞定~
方式二(推薦)：
第一步就是要根據這個JSON來寫出對應的實體類。用來存放數據。這個實體類如何寫的？其實非常簡單。因為一般不需要手動自己寫，當然，你要是喜歡也可以自己寫。不過我一般使用網站直接轉換。自己百度 查一下，JSON轉C#實體類，就會有很多網站給你轉。
我使用的是這個網站：http://www.bejson.com/convert/json2csharp/
{"message":"ok","nu":"367847964498","ischeck":"1","condition":"F00","com":"shunfeng","status":"200","state":"3","data":[{"time":"2017-09-21 09:33:09","ftime":"2017-09-21 09:33:09","context":"已簽收,感謝使用順豐,期待再次為您服務","location":""},{"time":"2017-09-21 09:09:48","ftime":"2017-09-21 09:09:48","context":"快件交給鞏向濤，正在派送途中（聯系電話：18806439871）","location":""},{"time":"2017-09-21 07:02:41","ftime":"2017-09-21 07:02:41","context":"快件到達 【淄博市桓台田庄速運營業點 】","location":""},{"time":"2017-09-20 15:32:00","ftime":"2017-09-20 15:32:00","context":"快件在【淄博市桓台縣工業街營業點】已裝車，准備發往下一站","location":""},{"time":"2017-09-20 13:37:08","ftime":"2017-09-20 13:37:08","context":"快件到達 【淄博市桓台縣工業街營業點】","location":""},{"time":"2017-09-20 10:47:07","ftime":"2017-09-20 10:47:07","context":"快件在【淄博高新集散中心】已裝車，准備發往下一站","location":""},{"time":"2017-09-20 10:15:47","ftime":"2017-09-20 10:15:47","context":"快件到達 【淄博高新集散中心】","location":""},{"time":"2017-09-19 23:20:18","ftime":"2017-09-19 23:20:18","context":"快件在【深圳總集散中心】已裝車，准備發往下一站","location":""},{"time":"2017-09-19 22:39:27","ftime":"2017-09-19 22:39:27","context":"快件到達 【深圳總集散中心】","location":""},{"time":"2017-09-19 18:57:33","ftime":"2017-09-19 18:57:33","context":"快件在【深圳龍華新區華聯社區營業部】已裝車，准備發往下一站","location":""},{"time":"2017-09-19 16:12:21","ftime":"2017-09-19 16:12:21","context":"順豐速運 已收取快件","location":""}]}
只需將JSON放到這個網站，自動給我們生成實體類即可
實體類：
using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace WindowsFormsApplication1 { /// <summary> /// JSON數據的實體類 /// </summary> public class Root { /// <summary> /// /// </summary> public string message { get; set; } /// <summary> /// /// </summary> public string nu { get; set; } /// <summary> /// /// </summary> public string ischeck { get; set; } /// <summary> /// /// </summary> public string condition { get; set; } /// <summary> /// /// </summary> public string com { get; set; } /// <summary> /// /// </summary> public string status { get; set; } /// <summary> /// /// </summary> public string state { get; set; } /// <summary> /// /// </summary> public List<DataItem> data { get; set; } } public class DataItem { /// <summary> /// /// </summary> public string time { get; set; } /// <summary> /// /// </summary> public string ftime { get; set; } /// <summary> /// 已簽收,感謝使用順豐,期待再次為您服務 /// </summary> public string context { get; set; } /// <summary> /// /// </summary> public string location { get; set; } } }
實體類創建好后，我們還需要一個DLL文件，Newtonsoft.Json.DLL,看方式一
封裝一個方法
/// <summary> /// 將JSON轉字符串(包括數組) /// </summary> /// <typeparam name="T"></typeparam> /// <param name="json"></param> /// <returns></returns> public static T JsonConvertObject<T>(string json) { return JsonConvert.DeserializeObject<T>(json); }
調用即可
以下JSON幫助類
