WPF WebBrowser控件-如何抑制脚本错误?

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);}
