也许我在重复这个问题,但我是第一次尝试这个问题,但我找不到与我的情况完全一样的东西。
我正在用 C# 编码并使用 JSON.NET 反序列化 json。json 文件来自 twitter 作为对此 GET 请求的响应:
https
://api.twitter.com/1/statuses/home_timeline.json?include_entities= true json 是来自 20 条最新推文(json 对象)的列表给定用户的 twitter 时间线和单个 json 对象的格式如下:

我使用此代码获取(反序列化)列表:
List<JsonObject> list = Newtonsoft.Json.JsonConvert.DeserializeObject<List<JsonObject>>(response);
'response' 保存我的 json。当我插入断点并观察 'list' 中的 json 对象时,我发现了这个:
{ "created_at": "Thu Sep 20 10:25:39 +0000 2012", "id": 248729631476314100, "id_str": "248729631476314112", "text": "请教专家并了解 v.2.2 的新功能在 #MongoDBPune (http://t.co/o5BA7zd6) 和 #MongoDBBangalore (http://t.co/7q3E2MBq)”,“来源”:“Socialrithmic”,“截断”:false,“in_reply_to_status_id”:null, “in_reply_to_status_id_str”:空,“in_reply_to_user_id”:空,“in_reply_to_user_id_str”:空,“in_reply_to_screen_name”:空,“用户”:[[[]],[[]],[[]],[[]],[ []]、[[]]、[[]]、[[]]、[[]]、[[]]、[[]]、[[]]、[[]]、[[]]、[[]]、[[]]、[[]]、[[]]、[[]]、 [[]]、[[]]、[[]]、[[]]、[[]]、[[]]、[[]]、[[]]、[[]]、[[]]、 [[]],[[]],[[]],[[]],[[]],[[]],[[]],[[]]],“地理”:空,“坐标” : null, "place": null, "contributors": null, "retweet_count": 1, "entities":[[[[[[]],[[[],[]]]],[[[]],[[[],[]]]]]],[[[[[]]],[[] ]、[[]]、[[[]、[]]]]、[[[]]、[[]]、[[]]、[[[]、[]]]]]]、[[] ] ], "收藏":假,“转推”:假,“可能敏感”:假}
我打算从所有 20 个 json 对象中收集所有主题标签。所以基本上我需要在实体内部导航到主题标签到文本。但如上所示,反序列化只是部分的。它不会反序列化任何嵌套的东西。
我该如何解决?请帮忙!
