閱讀rss飼料wp7與c＃

Question

如何閱讀從wp7應用程序使用c＃的「rss飼料」：「http://www.nyc.gov/apps/311/311Today.rss」？

我的XAML代碼：

<ListBox HorizontalAlignment="Left" Margin="10,10,0,0" Name="listBox1" VerticalAlignment="Top" > 
      <ListBox.ItemTemplate> 
       <DataTemplate> 
        <StackPanel VerticalAlignment="Top"> 
         <TextBlock x:Name="titleTxt" Height="30" Text="{Binding Title}" VerticalAlignment="Bottom" /> 
         <TextBlock x:Name="dateTxt" Height="30" Text="{Binding Date}" /> 
         <TextBlock x:Name="descTxt" Height="30" Text="{Binding Desc}" /> 
        </StackPanel> 
       </DataTemplate> 
      </ListBox.ItemTemplate> 
     </ListBox> 

我的C＃代碼：

private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e) 
    { 
     XDocument xDoc = XDocument.Load("http://www.nyc.gov/apps/311/311Today.rss"); 
     XNamespace content = XNamespace.Get("http://purl.org/rss/1.0/modules/content/"); 
     var items = xDoc.Descendants("item") 
       .Select(i => new 
       { 
        Title = i.Element("title").Value, 
        Date = DateTime.Parse(i.Element("pubDate").Value), 
        Desc = i.Element(content + "encoded").Value, 
       }) 
       .ToArray(); 
     listBox1.ItemsSource = items; 

    }
