WPF利用WebBrowser擷取HTML元素

擷取部落格園首頁左上方的那段文字“代碼改變世界”！

<Window x:Class="WpfWebBrose.MainWindow"        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"        Title="MainWindow" Height="768" Width="1024" Loaded="Window_Loaded">    <Grid>        <WebBrowser x:Name="wb" />    </Grid></Window>

cs:

    public partial class MainWindow : Window    {        public MainWindow()        {            InitializeComponent();            this.wb.LoadCompleted += (wb_Navigated);        }        private void Window_Loaded(object sender, RoutedEventArgs e)        {           wb.Navigate(new Uri("http://www.cnblogs.com"));        }        private  void wb_Navigated(object sender, NavigationEventArgs e)        {            var doc = this.wb.Document as HTMLDocument;            var item = doc.getElementById("site_nav_top");            MessageBox.Show(item.innerText);        }    }

有了Document就可以像web上一樣操作html元素了~
