Webbrowser控件使用IE内核版本

如果电脑上安装了IE8或者之后版本的IE浏览器，Webbrowser控件会使用IE7兼容模式来显示网页内容。解决方法是在注册表中为你的进程指定引用IE的版本号。

对于32位程序

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

对于64位程序

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

在对应的路径下添加你程序名字，如a.exe为名的value，DWORD值。

值选项：

10000(0×2710) IE10

9999 (0x270F) IE9 忽略html5

9000 (0×2328) IE9

8888 (0x22B8) IE8 忽略html5

8000 (0x1F40) IE8

7000 (0x1B58) IE7

代码实现

public static void SetIEVersion(string clientName)

{

var ver = 11001;

var version = new WebBrowser().Version;

if (version.Major == 11) ver = 11001;

else if (version.Major == 10) ver = 10001;

else if (version.Major == 9) ver = 9000;

else if (version.Major == 8) ver = 8000;

else if (version.Major == 7) ver = 7000;

SetIE($"{clientName}.exe", ver);

SetIE($"{clientName}.vshost.exe", ver);

}

public static void SetIE(string client, int version)

{

var subPath = @"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION";

var registryKey = OpenOrCreateSubKey(Registry.LocalMachine, subPath, true);

registryKey.SetValue(client, version, RegistryValueKind.DWord);

subPath = @"SOFTWARE\Microsoft\WOW6432Node\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION";

registryKey = OpenOrCreateSubKey(Registry.LocalMachine, subPath, true);

registryKey.SetValue(client, version, RegistryValueKind.DWord);

}
