Мой запрос ранее выглядел так:
private void getData()
{
// Api letőltése
WebClient webClient = new WebClient();
string url = "http://dev.virtualearth.net/REST/v1/Locations/"
+ _location + "?o=xml&key=App-asdf";
webClient.DownloadStringCompleted += (s, e) =>
{
if (e.Error != null)
return;
XDocument xmlLocation = XDocument.Parse(e.Result);
var ns = XNamespace.Get("http://schemas.microsoft.com/search/local/ws/rest/v1");
var locality = from q in xmlLocation.Descendants(ns + "Address")
select (string)q.Element(ns + "Locality").Value;
};
webClient.DownloadStringAsync(new Uri(url));
}
Почему он всегда возвращает null
?
Я хочу запросить местность, но моя переменная всегда содержит null
,Недавно я написал похожий программный код, который работал, но теперь у него есть пространство имен, и я не понимаю, в чем проблема.
