这是一个能够将WPFWebBrowser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);
}
