也许我是在重复这个问题,但我是第一次尝试这个问题,我找不到任何与我的情况完全相同的东西。
我正在用C#编写代码,并使用JSON.NET来反序列化json。作为对GET请求的响应,json文件来自twitter:
json是来自给定用户的twitter时间线的20个最新tweet (json对象)的列表,单个json对象的格式如下所示:
{

我使用这段代码获取(反序列化)列表:
List<JsonObject> list = Newtonsoft.Json.JsonConvert.DeserializeObject<List<JsonObject>>(response);当'response‘持有我的json.When时,我插入了一个断点并观察到'list’中的json对象,我发现如下:
{ "created_at":“清华9月20日10:25:39 +0000 2012年”,"id":248729631476314100,"id_str":"248729631476314112","text":“询问专家并学习在#MongoDBPune (http://t.co/o5BA7zd6)和#MongoDBBangalore (http://t.co/7q3E2MBq)第2.2节中的新内容”,“源代码”:“社会主义”,“截断”:false,"in_reply_to_status_id":null,"in_reply_to_status_id_str":null,"in_reply_to_user_id":null,"in_reply_to_user_id_str":null,"in_reply_to_screen_name":null,"user":[] ],[ [] ],[ [] ],[ [] ]、[]、[ ][ [] ]、[]、[ ][ [] ]、[]、[ ][ [] ]、[]、[ ][ [] ],[ [] ],"geo":空,“坐标”:空,“位置”:空,“贡献者”:空,"retweet_count":1,“实体”:[ ],[],[] ],[] ],[[]],]、[] ]、[]、[]、[]、[] ]、[ [] ]、[ [] ]、[ [] ]、[] ]、[ []、[ [] ]、“最爱”:false、“重发”:false、"possibly_sensitive":false }
我打算从所有的20个json objects..So收集所有的哈希标签,本质上我需要在实体中导航到哈希标记到文本。但如上文所示,反序列化只是部分的。它没有反序列化任何嵌套的东西。
我该怎么解决这个问题?请帮帮我!

天哪!是从this stackoverflow question那里得到的。谢谢@chill182 182!
你是怎么做到的:
ArrayList hashtags = new ArrayList();
JArray jsonDat = JArray.Parse(response);
for(int x = 0; x < jsonDat.Count(); x++)
{
JObject entity = JObject.Parse(jsonDat[x]["entities"].ToString());
JArray arrHashtags = JArray.Parse(entity["hashtags"].ToString());
for(int i=0; i < arrHashtags.Count(); i++)
{
JObject hashtagstuff = JObject.Parse(arrHashtags[i].ToString());
hashtags.Add(hashtagstuff["text"].ToString());
}
}不要忘记在名称空间中包括Linq :)
