Question

使用youtube api时抓住了WebException（https://gdata.youtube.com/feeds/api/users/ {user} / uploads？start-index = 1＆amp; max-results = 10＆amp; v = 2＆＃34;）这种情况总是发生，只有设备（Windows Phone-8）但是，在通过模拟器（WVGA-512）运行时，我找不到任何问题。

目前正在使用System.Net.WebClient的DownloadStringAsync(url);

请在下面找到例外。

也尝试使用HttpClient但没有成功。如果有人能帮助我，我会很感激。感谢
