c# - Winform WebBrowser 不显示 CSS

Question

我正在尝试导航到 Flying Toasters在 Winform WebBrowser 控件中，但动画似乎卡在第一帧。我猜这是网络浏览器的兼容性问题，因为当我导航到其他网站时，它说“不再支持 IE7 和 IE8”。为什么会发生这种情况，有什么办法可以解决这个问题吗？

Answer 1

如果您不覆盖注册表中的 Feature Browser Emultate 设置，将使用 Internet Explorer 7 渲染。

对于您的用户(当前用户)仅使用此 key :

• HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION

对于计算机/服务器上的所有用户，请使用此 key :

• 在 64 位应用程序上的 64 位应用程序或 32 位计算机上的 32 位应用程序:

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

• 在 64 位机器上的 32 位应用程序上:

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

例如，如果您的可执行文件名为 flying_toaster.exe。您必须添加一个名为 flying_toaster.exe 且值为 11001 的 DWORD 条目(以使用 Internet Exlporer 11 渲染)。

下面列出了完整的值列表(引用自 MSDN):
