这是一个能够将WPF
WebBrowser置于静默模式的C＃例程。您不能在WebBrowser初始化时调用它，因为它为时过早，而是在导航发生之后调用。这是带有wbMain
WebBrowser组件的WPF示例应用程序：
public partial class Window1 : Window{ public Window1() { InitializeComponent(); wbMain.Navigated += new NavigatedEventHandler(wbMain_Navigated); } void wbMain_Navigated(object sender, NavigationEventArgs e) { SetSilent(wbMain, true); // make it silent } private void button1_Click(object sender, RoutedEventArgs e) { wbMain.Navigate(new Uri("... some url...")); }}public static void SetSilent(WebBrowser browser, bool silent){ if (browser == null) throw new ArgumentNullException("browser"); // get an IWebBrowser2 from the document IOleServiceProvider sp = browser.document as IOleServiceProvider; if (sp != null) { Guid IID_IWebBrowserApp = new Guid("0002DF05-0000-0000-C000-000000000046"); Guid IID_IWebBrowser2 = new Guid("D30C1661-CDAF-11d0-8A3E-00C04FC9E26E"); object webBrowser; sp.QueryService(ref IID_IWebBrowserApp, ref IID_IWebBrowser2, out webBrowser); if (webBrowser != null) { webBrowser.GetType().InvokeMember("Silent", BindingFlags.Instance | BindingFlags.Public | BindingFlags.PutDispProperty, null, webBrowser, new object[] { silent }); } }}[Comimport, Guid("6D5140C1-7436-11CE-8034-00AA006009FA"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]private interface IOleServiceProvider{ [PreserveSig] int QueryService([In] ref Guid guidService, [In] ref Guid riid, [MarshalAs(UnmanagedType.IDispatch)] out object ppvObject);}
