Newtonsoft JSON.Net告訴我JSON無效。 JSONLint說，它的確定

Question

我做以下URL調用返回JSON：

http://ebird.org/ws1.1/data/obs/geo_spp/recent?lng=-83.71307&lat=41.60906&sci=Bubo virginianus&dist=50&back=30&maxResults=100&locale=en_US&fmt=json&includeProvisional=true

我再處理結果如下（其中URL包含上述網址）：

using (var webClient = new System.Net.WebClient()) { 
     string response = webClient.DownloadString(url.ToString()); 

     json = JObject.Parse(response); 
    } 

Parse語句拋出一個異常，告訴我JSON無效。但是，當我將結果粘貼到JSONLint中時，它告訴我它是有效的JSON。錯誤是：

{"Error reading JObject from JsonReader. Current JsonReader item is not an object: StartArray. Path '', line 1, position 1."} 

通過調用返回的實際JSON如下（直接從VS 2013調試器）：

問題是你的JSON字符串，而有效的，並不代表一個JSON 對象，它代表一個JSON 數組。因此，要解析它，您需要使用JArray.Parse()或JToken.Parse()。
