Answers:
我看到了维尔的答案。我认为是正确的,但是我没有为我工作。也许我正在使用.NET 4,并且正在使用64x OS,所以请检查一下。
您可以进行设置或在启动应用程序时进行检查:
private void Form1_Load(object sender, EventArgs e)
{
var appName = Process.GetCurrentProcess().ProcessName + ".exe";
SetIE8KeyforWebBrowserControl(appName);
}
private void SetIE8KeyforWebBrowserControl(string appName)
{
RegistryKey Regkey = null;
try
{
// For 64 bit machine
if (Environment.Is64BitOperatingSystem)
Regkey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\\Wow6432Node\\Microsoft\\Internet Explorer\\Main\\FeatureControl\\FEATURE_BROWSER_EMULATION", true);
else //For 32 bit machine
Regkey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\\Microsoft\\Internet Explorer\\Main\\FeatureControl\\FEATURE_BROWSER_EMULATION", true);
// If the path is not correct or
// if the user haven't priviledges to access the registry
if (Regkey == null)
{
MessageBox.Show("Application Settings Failed - Address Not found");
return;
}
string FindAppkey = Convert.ToString(Regkey.GetValue(appName));
// Check if key is already present
if (FindAppkey == "8000")
{
MessageBox.Show("Required Application Settings Present");
Regkey.Close();
return;
}
// If a key is not present add the key, Key value 8000 (decimal)
if (string.IsNullOrEmpty(FindAppkey))
Regkey.SetValue(appName, unchecked((int)0x1F40), RegistryValueKind.DWord);
// Check for the key after adding
FindAppkey = Convert.ToString(Regkey.GetValue(appName));
if (FindAppkey == "8000")
MessageBox.Show("Application Settings Applied Successfully");
else
MessageBox.Show("Application Settings Failed, Ref: " + FindAppkey);
}
catch (Exception ex)
{
MessageBox.Show("Application Settings Failed");
MessageBox.Show(ex.Message);
}
finally
{
// Close the Registry
if (Regkey != null)
Regkey.Close();
}
}
您可能会发现messagebox.show,仅用于测试。

我看到像Skype这样的应用程序使用10001。我不知道。
注意
安装程序将更改注册表。您可能需要在清单文件中添加一行,以避免由于注册表更改权限而导致的错误:
<requestedExecutionLevel level="highestAvailable" uiAccess="false" />

这是一个将在Windows上获取IE的最新版本并进行相应更改的类;
public class WebBrowserHelper
{
public static int GetEmbVersion()
{
int ieVer = GetBrowserVersion();
if (ieVer > 9)
return ieVer * 1000 + 1;
if (ieVer > 7)
return ieVer * 1111;
return 7000;
} // End Function GetEmbVersion
public static void FixBrowserVersion()
{
string appName = System.IO.Path.GetFileNameWithoutExtension(System.Reflection.Assembly.GetExecutingAssembly().Location);
FixBrowserVersion(appName);
}
public static void FixBrowserVersion(string appName)
{
FixBrowserVersion(appName, GetEmbVersion());
} // End Sub FixBrowserVersion
// FixBrowserVersion("<YourAppName>", 9000);
public static void FixBrowserVersion(string appName, int ieVer)
{
FixBrowserVersion_Internal("HKEY_LOCAL_MACHINE", appName + ".exe", ieVer);
FixBrowserVersion_Internal("HKEY_CURRENT_USER", appName + ".exe", ieVer);
FixBrowserVersion_Internal("HKEY_LOCAL_MACHINE", appName + ".vshost.exe", ieVer);
FixBrowserVersion_Internal("HKEY_CURRENT_USER", appName + ".vshost.exe", ieVer);
} // End Sub FixBrowserVersion
private static void FixBrowserVersion_Internal(string root, string appName, int ieVer)
{
try
{
//For 64 bit Machine
if (Environment.Is64BitOperatingSystem)
Microsoft.Win32.Registry.SetValue(root + @"\Software\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", appName, ieVer);
else //For 32 bit Machine
Microsoft.Win32.Registry.SetValue(root + @"\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", appName, ieVer);
}
catch (Exception)
{
// some config will hit access rights exceptions
// this is why we try with both LOCAL_MACHINE and CURRENT_USER
}
} // End Sub FixBrowserVersion_Internal
public static int GetBrowserVersion()
{
// string strKeyPath = @"HKLM\SOFTWARE\Microsoft\Internet Explorer";
string strKeyPath = @"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer";
string[] ls = new string[] { "svcVersion", "svcUpdateVersion", "Version", "W2kVersion" };
int maxVer = 0;
for (int i = 0; i < ls.Length; ++i)
{
object objVal = Microsoft.Win32.Registry.GetValue(strKeyPath, ls[i], "0");
string strVal = System.Convert.ToString(objVal);
if (strVal != null)
{
int iPos = strVal.IndexOf('.');
if (iPos > 0)
strVal = strVal.Substring(0, iPos);
int res = 0;
if (int.TryParse(strVal, out res))
maxVer = Math.Max(maxVer, res);
} // End if (strVal != null)
} // Next i
return maxVer;
} // End Function GetBrowserVersion
}
使用类如下
WebBrowserHelper.FixBrowserVersion();
WebBrowserHelper.FixBrowserVersion("SomeAppName");
WebBrowserHelper.FixBrowserVersion("SomeAppName",intIeVer);
您可能会遇到Windows 10的可比性问题,可能由于您的网站本身而需要添加此元标记

使用来自MSDN的值:
int BrowserVer, RegVal;
// get the installed IE version
using (WebBrowser Wb = new WebBrowser())
BrowserVer = Wb.Version.Major;
// set the appropriate IE version
if (BrowserVer >= 11)
RegVal = 11001;
else if (BrowserVer == 10)
RegVal = 10001;
else if (BrowserVer == 9)
RegVal = 9999;
else if (BrowserVer == 8)
RegVal = 8888;
else
RegVal = 7000;
// set the actual key
using (RegistryKey Key = Registry.CurrentUser.CreateSubKey(@"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", RegistryKeyPermissionCheck.ReadWriteSubTree))
if (Key.GetValue(System.Diagnostics.Process.GetCurrentProcess().ProcessName + ".exe") == null)
Key.SetValue(System.Diagnostics.Process.GetCurrentProcess().ProcessName + ".exe", RegVal, RegistryValueKind.DWord);
CreateSubKey
应该使用更好的代码之外,OpenSubKey
因为如果键不存在,OpenSubKey将返回null。
var appName = System.Diagnostics.Process.GetCurrentProcess().ProcessName + ".exe";
using (var Key = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", true))
Key.SetValue(appName, 99999, RegistryValueKind.DWord);
根据我在这里阅读的内容(控制WebBrowser控件兼容性:
如果我将FEATURE_BROWSER_EMULATION文档模式值设置为高于客户端上的IE版本,会发生什么?
显然,浏览器控件只能支持小于或等于客户端上安装的IE版本的文档模式。使用FEATURE_BROWSER_EMULATION密钥最适合已部署并支持浏览器版本的企业业务应用程序。如果您将值设置为浏览器模式的版本高于客户端上安装的浏览器版本,则浏览器控件将选择可用的最高文档模式。
最简单的事情是放一个非常高的十进制数字...
SOFTWARE\WOW6432Node\Microsoft...

我能够实现Luca的解决方案,但是我必须进行一些更改才能使其正常工作。我的目标是将D3.js与Windows窗体应用程序(针对.NET 2.0)的Web浏览器控件一起使用。现在对我有用。我希望这可以帮助其他人。

另外,我在项目的设置中添加了一个字符串(ie_emulation),其值为11999。该值似乎适用于IE11(11.0.15)。
接下来,我必须更改我的应用程序的权限以允许访问注册表。这可以通过向项目中添加新项(使用VS2012)来完成。在“常规项目”下,选择“应用程序清单文件”。将级别从asInvoker更改为requireAdministrator(如下所示)。
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
如果阅读此文件的人试图将D3.js与Webbrowser控件一起使用,则可能必须修改JSON数据以存储在HTML页面内的变量中,因为D3.json使用XmlHttpRequest(更易于与Web服务器一起使用)。在进行了上述更改之后,我的Windows窗体能够加载调用D3的本地HTML文件。
结合RooiWillie和MohD的答案,
并记住以管理权限运行您的应用程序。
