来自linq结果的pagetitle

Question

我怎么能将我的pagetitle绑定到linq结果？如果我有这个代码：

    var data = from query in loadedData.Descendants("article")
                   select new article
                   {
                       Title = (string)query.Element("title").Value,
                       SubTitle = (string)query.Element("subtitle").Value,
                       Content = (string)query.Element("content").Value
                   };

如果我使用：

    <TextBlock x:Name="PageTitle" Text="{Binding Title}" Margin="9,-7,0,0" Style="    {StaticResource PhoneTextTitle1Style}" Foreground="White" />

它不起作用？ ：|
