WPF WebBrowser控件-如何抑制脚本错误?

c#

我在这里找到了类似的问题:

使用WPF
WebBrowser控件时如何抑制脚本错误?

但是这些解决方案都不适合我。我需要停止弹出窗口的显示,因为我正在使用WebBrowser来自动执行网站上的管理任务。

SuppressScriptErrors 在我的WebControl上似乎不是可用属性:(

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);
}
