         {
            "id":"201852446499743",
            "name":"Kalna@kalna",
            "type":"LIKE"
         },
         {
            "id":"178345282632225",
            "name":"Riya Modak",
            "type":"LOVE"
         }
      ],
      "paging":{
         "cursors":{
            "before":"TWpBeE9EVXlORFEyTkRrNU56UXpPakUwT0RFeE1UVXhOekE2TWpVME1EazJNVFl4TXc9PQZDZD",

         }
      }
   },
   "id":"1402884576396518"
}

Answer 1

快速的方法是deserialize进入dynamic类，如下所示：

// Fetch your JSON
string json = // however you retrieve this JSON

// Use JSON.NET to deserialize into dynamic
var result = JsonConvert.DeserializeObject<dynamic>(json);

// Loop through each "reaction"
foreach (var data in result.reactions.data)
{
    // Show ID (can get name and type also)
    Console.WriteLine(data.id.ToString());
}

输出：

201852446499743
178345282632225

您只需导入System.Web.Script.Serialization - 命名空间。然后，您可以使用JavaScriptSerializer反序列化您的JSON字符串：

Dictionary<object, object> data = new JavaScriptSerializer().Deserialize<Dictionary<object, object>>(yourJSONString);

这将返回一个字典，您可以在其中找到键＆＃34;数据＆＃34;。

如何在c＃中使用newtonsoft json.net从这个json数据中获取数据集合
