WPF Webbrowser 如何缩小页面加载事件?

WPF Webbrowser How do I zoom out on Page loaded event?

这个事件处理程序returns:

System.Runtime.InteropServices.COMException: 'Unknown name. (Exception from HRESULT: 0x80020006 (DISP_E_UNKNOWNNAME))'

代码:

private void Browser_Loaded(object sender, NavigationEventArgs e)
    {
        browser.InvokeScript("Document.Body.Style =" + "zoom:80%");
    }

我尝试了很多网上找到的解决方案,但 none 似乎对我有用 请指教

试试这个

private void Browser_Loaded(object sender, NavigationEventArgs e)
    {
        var zoom = 0.8;
        mshtml.IHTMLDocument2 doc = browser.Document as mshtml.IHTMLDocument2;
        doc.parentWindow.execScript("document.body.style.zoom=" + zoom.ToString().Replace(",", ".") + ";");
    }

它对我有用。

别忘了参考Microsoft.mshtml
