Question

如果我在浏览器中查看url获取：

{"status":{"message":"the daily limit of 30000 credits for demo has been exceeded. Please use an application specific account. Do not use the demo account for your application.","value":18}}

因此JSON有两个元素“status”和“value”

按照以下示例。当我DeserializeObject(text) data.Count返回3

时

但wc.DownloadString(url)返回：

"{\"status\":{\"message\":\"the daily limit of 30000 credits for demo has been exceeded. Please use an application specific account. Do not use the demo account for your application.\",\"value\":18}}"

在DeserializeObject(json) data.Count之后返回null。

我试试：

json = json.Replace(@"\", "");

但是“\”并没有删除，而且我也不想删除原始JSON上的任何“\”。

public class HomeController : Controller
{
    static string url = "http://api.geonames.org/findNearByWeatherJSON?lat=-68,1&lng=10,2&username=demo";

    public ActionResult Index()
    {
        var text = @"[{'Name':'AAA','Age':'22','Job':'PPP'},
                {'Name':'BBB','Age':'25','Job':'QQQ'},
                {'Name':'CCC','Age':'38','Job':'RRR'}]";

        using (WebClient wc = new WebClient())
        {
            var json = wc.DownloadString(url);
            dynamic data = Newtonsoft.Json.JsonConvert.DeserializeObject(text); 
            // data.Count = 3


            data = Newtonsoft.Json.JsonConvert.DeserializeObject(json);
            // data.Count = null
        }

        return View();
    }
}

注意：即使重复的问题显示为什么调试器中的显示与文本显示不同，问题是DeserializeObject无法正常工作
