在C＃.NET中使用Yahoo API的GeoCode

Question

幾天前，我正在使用csome代碼正常工作。我使用雅虎的API來獲取郵政編碼logitude和緯度的代碼如下：

string url = string.Format("http://where.yahooapis.com/geocode?flags=J&appid=xxxx&location={0}", postcode); 

     decimal latitude = 0; 
     decimal longitude = 0; 
     Dictionary<string, decimal> geoCode = new Dictionary<string, decimal>(); 

     dynamic yahooResults = new Uri(url).GetDynamicJsonObject(); 
     foreach (var result in yahooResults.ResultSet.Results) 
     { 
      latitude = (decimal)result.latitude; 
      longitude = (decimal)result.longitude; 
     } 

     geoCode.Add("latitude", latitude); 
     geoCode.Add("longitude", longitude); 

     return geoCode; 

正如我所說的代碼是前幾天做工精細但總是返回現在logitude和緯度爲0。我包括從雅虎迴應如下：

{ 
    "@lang": "en-US", 
    "ResultSet": { 
    "@version": "2.0", 
    "@lang": "en-US", 
    "Error": "0", 
    "ErrorMessage": "No error", 
    "Locale": "en-US", 
    "Found": "1", 
    "Quality": "60", 
    "Result": { 
     "quality": "60", 
     "latitude": "51.62071", 
     "longitude": "-0.23616", 
     "offsetlat": "51.620708", 
     "offsetlon": "-0.23616", 
     "radius": "4200", 
     "name": "", 
     "line1": "", 
     "line2": "London", 
     "line3": "NW7", 
     "line4": "United Kingdom", 
     "house": "", 
     "street": "", 
     "xstreet": "", 
     "unittype": "", 
     "unit": "", 
     "postal": "NW7", 
     "neighborhood": "", 
     "city": "London", 
     "county": "Greater London", 
     "state": "England", 
     "country": "United Kingdom", 
     "countrycode": "GB", 
     "statecode": "ENG", 
     "countycode": "LND", 
     "uzip": "NW7", 
     "hash": "", 
     "woeid": "26787971", 
     "woetype": "11" 
    } 
    } 
} 

對不起，格式化堆棧似乎不想格式化好！顯然有返回的緯度和緯度。我確信這是簡單的，但我不能看到它的愛或金錢，任何幫助將不勝感激。

似乎yahoo不會再返回Result數組。下面的代碼作品

dynamic yahooResults =.....; 

var latitude = (decimal)yahooResults.ResultSet.Result.latitude; 
var longitude = (decimal)yahooResults.ResultSet.Result.longitude;
