我已經開始構建一個應用程序來從World Weather Online獲取潮汐信息，天氣信息，地圖繪製等功能，但無法獲得JSON響應。試圖通過JSON.net接收JSON
我已經通過NuGet安裝了JSON.net，我正在運行Windows 8.1。我只能通過將我的JSON URL粘貼到實際的瀏覽器中來查看數據。然後在json2sharp上使用它的輸出來創建下面我的代碼的底部。
嘗試http://www.codeproject.com/Tips/397574/Use-Csharp-to-get-JSON-Data-from-the-Web-and-Map-i和How to get a json string from url?。

我不知道無論您正在使用的溢價或免費版本，但在無論如何，你絕對不應該分享你的API密鑰。 。 。 （如果是優質的人可以使用它，你最終會付錢） –
你應該澄清究竟是怎麼回事。拋出什麼異常，等等。 –
