Answer 1

This is because the WebBrowser class emulates IE and therefore will have a HKEY setting the version of IE used in the emulation. 这是因为WebBrowser类模拟IE，因此将具有HKEY来设置模拟中使用的IE版本。

Below are a couple of suggestions or alternatives. 以下是一些建议或替代方案。

Meta Tag 元标记

<meta http-equiv="X-UA-Compatible" content="IE=10" />

Add the above to your HTML and it will try and force the browser to show the content in IE10. 将以上内容添加到HTML中，它将尝试强制浏览器在IE10中显示内容。

HKEY Change on machine HKEY在机器上更换

Find the below HKEY's 查找以下HKEY的

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION

and change or add your App to the values like so 然后将您的应用更改或添加到类似的值

FEATURE_BROWSER_EMULATION "myAppName.exe"=10000

HKEY Change in Code HKEY代码更改

To do the same as above but within the code, use the following: 若要执行与上述相同的操作，但在代码内，请使用以下命令：

RegistryKey registrybrowser = Registry.LocalMachine.OpenSubKey
           (@"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", true);
        registrybrowser.SetValue("myAppName.exe", 10000, RegistryValueKind.DWord);

Answer 2

I think the WebBrowser is stuck at IE7 or IE8. 我认为WebBrowser卡在IE7或IE8上。 I tried some of these hacks a few years ago to change its version: 几年前，我尝试了其中一些黑客措施来更改其版本：

Also Use latest version of Internet Explorer in the webbrowser control 在浏览器控件中也使用最新版本的Internet Explorer
