问题 I need to get data from this list, however when I put my foreach of a runtime error saying that the list contains null objects. But if I remove the foreach and put a breakpoint on the line where listbox.itemsSource receives the list, I see that I have the list loaded with all items correctly. var imgs = e.Document.DocumentNode.SelectNodes(@"//img[@src]") .Select(img => new { Link = img.Attributes["src"].Value, Title = img.Attributes["alt"].Value, }).ToList(); listBoxPopular.ItemsSource = imgs

问题 I've seen a tutorial about how to play local files using a background agent in WP7 Mango but it specifically states that the tutorial is related to local files: http://msdn.microsoft.com/en-us/library/hh202978(v=VS.92).aspx Does a similar tutorial exist for streaming files from the web? 回答1: I've used the same tutorial, and it works fine if you want to play something like a podcast that is stored as an mp3 file on a webserver.

问题 I'm trying to read the metadata of a mp3 file stored in IsolatedStorage using TagLib. I know TagLib normally only take a file path as input but as WP uses a sandbox environment I need to use a stream. Following this tutorial (http://www.geekchamp.com/articles/reading-and-writing-metadata-tags-with-taglib) I created a iFileAbstraction interface: public class SimpleFile { public SimpleFile(string Name, Stream Stream) { this.Name = Name; this.Stream = Stream; } public string Name { get; set; }
