c# - 通过linq获取乘法结果

Question

我对linq有问题，我想从youtube xml中获得乘法结果，但是这段代码仅给我一个结果，有人知道如何解决此问题？

key = @"http://gdata.youtube.com/feeds/api/videos?q="+keys+@"&orderby=relevance";
var youtube = XDocument.Load(key);
var urls = (from item in youtube.Elements("{http://www.w3.org/2005/Atom}feed")
                select new
                {
                    soundName = item.Element("{http://www.w3.org/2005/Atom}entry").Element("{http://www.w3.org/2005/Atom}title").ToString(),
                    url = item.Element("{http://www.w3.org/2005/Atom}entry").Element("{http://www.w3.org/2005/Atom}id").ToString(),
                });

youtube xml:
http://gdata.youtube.com/feeds/api/videos?q=keyword&orderby=relevance
