JSON與System.Web.Helpers中的多個圖層

我一直在使用一個服務，返回一個數組裏面的數組和JSON文件。第二層數組的問題是我似乎無法使用它。的JSON看起來是這樣的：JSON與System.Web.Helpers中的多個圖層

     "copyright": "George Tames/The New York Times" 
    } 
    ], 
    "short_url": "urlLocation" 
}

我試圖訪問它是這樣的：

NewsArticle newsArticle = new NewsArticle(); 
      newsArticle.category = data.results[counter].section; 
      newsArticle.title = data.results[counter].title; 
      newsArticle.fullText = data.results[counter][email protected]; 
      DynamicJsonArray multimedia = data.results[counter].multimedia; 
      newsArticle.image = multimedia[0].url; 
      return_value.Add(newsArticle);

我得到一個「索引數組的範圍之外。」「多媒體」陣列上的例外。我的語法有什麼問題嗎？

使用調試器，您可能沒有正確反序列化它。 –

什麼是代碼中的'counter'？請提供您用於反序列化JSON的代碼。 – rpeshkov

我正在使用Sytem.Web.Helper庫。在JSON文件的根目錄中給出了這個文件中有多少條目，我將它們存儲在計數器變量中。 – Deadwalker

服務的返回值似乎存在問題。第一個結果不包含該數組，這就是爲什麼我得到索引超出界限的例外。謝謝奧廖爾Eraki！
