WebBrowser 未正确显示页面

Question

我正在尝试在 WPF 中使用 WebBrowser。我只是像这样使用 Navigate 方法：

   public MainWindow()
    {
        InitializeComponent();
        browser.Navigate("https://whosebug.com/");
    }

首先，它显示了很多与脚本相关的消息：

脚本错误屏幕截图

然后显示不正确的页面截图

我找到了这个 WPF WebBrowser control - how to suppress script errors? 并使用了这个代码：

 public MainWindow()
    {
        InitializeComponent();
        browser.Navigated += new NavigatedEventHandler(Browser_Navigated);
        browser.Navigate("https://whosebug.com/");
    }

    private void Browser_Navigated(object sender, NavigationEventArgs e)
    {
        SetSilent(browser, true);
    }

    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);
    }

此后没有错误信息，但页面仍然不正确。

有人知道如何解决这个问题吗？这是 xaml 代码：

<Window x:Class="MyWebBrowser.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:local="clr-namespace:MyWebBrowser"
    mc:Ignorable="d"
    Height="300" Width="450"
    Title="MainWindow">
<Grid>
    <WebBrowser Name="browser"></WebBrowser>
</Grid>

wpf 中的网页浏览器控件使用了相当古老的 IE 网页浏览器引擎，所以难怪它不能显示现代网站。您可以导航至 http://html5test.com to get an exact IE version it is using. I suggest using more modern web browser engine and a wrapper to embed it. Take a look at https://cefsharp.github.io
