C# 我想用C语言获取json解析数据

这是我的JObject.Parse字符串

{"topic":{"account_id":190884,"created_at":"2015-01-31T16:35:59+05:00","delta":true,"forum_id":5000225377,"hits":0,"id":5000025527,"import_id":null,"last_post_id":5000040596,"locked":false,"merged_topic_id":null,"posts_count":0,"published":true,"replied_at":"2015-01-31T16:35:59+05:00","replied_by":5005399997,"stamp_type":null,"sticky":0,"title":"I want use API of Freshdesk.","updated_at":"2015-01-31T16:35:59+05:00","user_id":5005399997,"user_votes":0,"posts":[{"account_id":190884,"answer":false,"body":" I want to use API of Freshdesk to get forums of Freshdesk.

我想用C从这个字符串中获取帖子的值。任何人都可以帮助我如何从这个字符串中获取帖子的值。

使用Newtonsoft的Json.net

这是一个易于使用的库：

例如：

string json = @"{
  'Name': 'Bad Boys',
  'ReleaseDate': '1995-4-7T00:00:00',
  'Genres': [
  'Action',
  'Comedy'
]
}";

Movie m = JsonConvert.DeserializeObject<Movie>(json);

string name = m.Name;

有很多类似的问题。请参阅，例如，我在应用程序中包括了newtonsoft。但这对我没有帮助。我也试过这个。在测试中有我的字符串。这是我的其他课程。公共类主题{public int account_id{get；set；}公共ICollection posts{get；set；}公共类Post{public int account_id{get；set；}公共bool answer{get；set；}公共字符串体{get；set；}公共字符串体{html{get；set；}主题ABC=JsonConvert.DeserializeObjecttest；当我调试它并检查ABC的值时。显示空值。在给定的字符串中，有一个额外的级别包含主题对象。添加这个类：公共类Root{public Topic Topic{get；set；}}}，然后只调用Root ABC=JsonConvert.DeserializeObjecttest；这在.netcore中不起作用

var s=<json_string>;
var firstPost = JObject.Parse(s)["topic"]["posts"][0];
string postBody = (string)firstPost["body"];
