PowerShell:如何在WPF WebBrowser中抑制脚本错误?

Question

我在PowerShell中实现了WPF Webbrowser。但是，我无法抑制脚本错误。

你能指导如何抑制脚本错误吗？

WPF XAML 代码：

<Grid
xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">


<DockPanel >
<WebBrowser Name="WebBrowser" DockPanel.Dock="Left" HorizontalAlignment="Stretch"  VerticalAlignment="Stretch" >
</WebBrowser>
</DockPanel>



</Grid>

您需要将浏览器置于静默模式。

在 C# 中，它将是：

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);
}

如果这对你没有帮助，也许你可以使用Windows Forms Browser并使用2.0的WebBrowser属性：SuppressScriptErrors。
