c# - 隐藏 webBrowser 滚动条 wpf

Question

我有一个网络浏览器，我正在加载一个 .html 文件。问题是虽然我已经将 ScrollViewer.VerticalScrollBarVisibility 设置为“Hidden”，但滚动条仍然可见。

这个方法我也试过，还是不行

<WebBrowser x:Name="personalizedWebBrowser" HorizontalAlignment="Left"  VerticalAlignment="Top" 
                ScrollViewer.CanContentScroll="False"
                ScrollViewer.HorizontalScrollBarVisibility="Hidden" 
                ScrollViewer.VerticalScrollBarVisibility="Hidden"
                LoadCompleted="wb_LoadCompleted"/>


private void wb_LoadCompleted(object sender, System.Windows.Navigation.NavigationEventArgs e)
{
     mshtml.IHTMLDocument2 dom = (mshtml.IHTMLDocument2)personalizedWebBrowser.Document;
     dom.body.style.overflow = "hidden";
}

请问您还有什么建议吗？

我通过在 wpf 项目中使用 Windows 窗体 WebBrowser 控件解决了这个问题:

    private void Window_Loaded(object sender, RoutedEventArgs e)
    {
        string curDir = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location) + "\\help";

        System.Windows.Forms.Integration.WindowsFormsHost host =
            new System.Windows.Forms.Integration.WindowsFormsHost();
        System.Windows.Forms.WebBrowser webBrowser1 = new System.Windows.Forms.WebBrowser();
        host.Child = webBrowser1;

        webBrowser1.DocumentCompleted += webBrowser1_DocumentCompleted;

        string sFileName = "file:///{0}/index.html";

        webBrowser1.Url = new Uri(String.Format(sFileName, curDir));
        webBrowser1.ScrollBarsEnabled = false;
        this.grid1.Children.Add(host);
    }

    private void webBrowser1_DocumentCompleted(object sender, System.Windows.Forms.WebBrowserDocumentCompletedEventArgs e)
    {
        System.Windows.Forms.WebBrowser webBrowser1 = sender as System.Windows.Forms.WebBrowser;
        if(webBrowser1==null)return;
        webBrowser1.Document.Body.Style = "overflow:hidden";
    }

grid1 用作 webBrowser1 的容器

我们还需要在项目中添加以下程序集引用:WindowsFormsIntegration，System.Windows.Forms
