Json反序列化解析无效的Json对象 [英] Json Deserialization parsing non valid Json object

问题描述

我正在尝试反序列化从Web API检索到的Json对象到强类型对象列表中，如下所示:

I'm trying to deserialize A Json object retrived from Web API into list of strong type objects as follows :

WebClient wc = new WebClient();

WebClient wc = new WebClient();

        // Downloading & Deserializing the Json file
        var jsonMain = wc.DownloadString("http://api.flexianalysis.com/services/FlexiAnalysisService.svc/FlexiAnalysisNews?key=___&catagory=Forex");


        JObject token2 = JObject.Parse(jsonMain);

        List<News> listNews = new List<News>();

        foreach (var result in token2["d"])
        {
            news = new News();
            news.id = (string)result["ID"];
            news.Title = (string)result["Title"];
            news.Date = (string)result["PublishingDate"];
            news.Content = (string)result["News"];
            listNews.Add(news);
        }

        return View(listNews);

问题是我总是以1个字符串的形式获取结果，因为解析器无法解析有效的Json对象. (我想这是无效字符，无法正确解析)...

The problem is that I always get the result as 1 string, Because the parser does not parse a valid Json object. (I guess it get's to invalid character and can't get it parsed correctly)...

有人有什么想法吗?

推荐答案

您需要JArray results = JArray.Parse(token2["d"].ToString());

请尝试

WebClient wc = new WebClient();
// Downloading & Deserializing the Json file
var jsonMain = wc.DownloadString("http://api.flexianalysis.com/services/FlexiAnalysisService.svc/FlexiAnalysisNews?key=gZ_lhbJ_46ThmvEki2lF&catagory=Forex");


JObject token2 = JObject.Parse(jsonMain);
JArray results = JArray.Parse(token2["d"].ToString());

List<News> listNews = new List<News>();
foreach (var result in results)
{
    news = new News();
    news.id = (string)result["ID"];
    news.Title = (string)result["Title"];
    news.Date = (string)result["PublishingDate"];
    news.Content = (string)result["News"];
    listNews.Add(news);
}

return View(listNews);
