【中文标题】在 webbrowser 控件中使用最新版本的 Internet Explorer【英文标题】：Use latest version of Internet Explorer in the webbrowser control 【发布时间】：2013-07-29 03:22:59 【问题描述】：C# Windows Forms 中 webbrowser 控件的默认版本 应用程序是 7。我已经通过文章 Browser Emulation 更改为 9，但是如何在 webbrowser 控件中使用已安装的 Internet Explorer 的最新版本？
【问题讨论】：
【参考方案1】：我看到了 Veer 的回答。我认为这是对的，但它并没有为我工作。也许我正在使用 .NET 4 并且正在使用 64x 操作系统，所以请检查一下。
您可以在应用程序启动时进行设置或检查：
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();
你可能会发现 messagebox.show，只是为了测试。
键如下：
11001 (0x2AF9) - Internet Explorer 11。网页在 IE11 中显示 边缘模式，与

参考：MSDN: Internet Feature Controls
我看到像 Skype 这样的应用程序使用 10001。我不知道。
注意
安装应用程序将更改注册表。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" />

这是一个类将在 windows 上获取最新版本的 IE 并进行应有的更改；
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);
您可能在 Windows 10 的可比性方面遇到问题，这可能是由于您的网站本身造成的 您可能需要添加此元标记

【讨论】：
来自 MSDN：“注册表重定向器通过在 WOW64 上提供注册表某些部分的单独逻辑视图来隔离 32 位和 64 位应用程序。注册表重定向器拦截 32 位和 64 位注册表调用它们各自的逻辑注册表视图并将它们映射到相应的物理注册表位置。重定向过程对应用程序是透明的。因此，32 位应用程序可以访问注册表数据，就好像它在 32 位 Windows 上运行一样，即使数据存储在 64 位 Windows 上的不同位置”您无需担心 Wow6432Node 你也可以使用HKEY_CURRENT_USER，不需要管理员。 一个建议：将Environment.Is64BitOperatingSystem 更改为Environment.Is64BitProcess。
@JobaDiniz 请检查更新 1 会帮助你:)
我知道这已经有几年的历史了，但对于未来的读者：您的应用程序不需要检查它是否在 64 位系统甚至 64 位进程中运行。 64 位版本的 Windows 实现了 Registry Redirector，它将自动将在 64 位系统上运行的 32 位应用程序重定向到 Wow6432Node 子项。您的应用程序不需要做任何额外的事情来适应这个“新”键。【参考方案2】：
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);
【讨论】：
老兄，这是获取版本的一种更简单的方法...谢谢，这对我有用！ 谢谢，很好的代码，除了应该使用CreateSubKey 而不是OpenSubKey，因为如果密钥不存在，OpenSubKey 将返回 null。
好点！我编辑了答案以使用 CreateSubKey 并仅在尚未设置值时设置值。
太棒了！太感谢了。这应该是最好的答案。尝试了上面的怪物解决方案，但没有区别。这接近了它。再次感谢！
@MarkNS 好吧，在这种情况下，您可以先进行空检查，然后再进行版本检查，然后再编写。其背后的逻辑只是为了避免不断写入注册表，但如果您对此感到满意，您可以简单地删除空检查。【参考方案3】：
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);
根据我在这里读到的内容 (Controlling WebBrowser Control Compatibility:
如果我在客户端将 FEATURE_BROWSER_EMULATION 文档模式值设置为高于 IE 版本会怎样？
显然，浏览器控件只能支持小于或等于客户端安装的IE版本的文档模式。使用 FEATURE_BROWSER_EMULATION 键最适用于部署了浏览器并支持版本的企业业务线应用程序。 如果您将该值设置为比客户端上安装的浏览器版本更高的浏览器模式，浏览器控件将选择可用的最高文档模式。
最简单的就是放一个很高的十进制数...
【讨论】：
注意：如果您在win64上运行32位应用程序，则需要编辑的密钥在SOFTWARE\WOW6432Node\Microsoft...下。它会在代码中自动重定向，但如果您打开 regedit，可能会让您大吃一惊。
短小甜甜。对我来说Registry.LocalMachine.OpenSubKey(".. 以管理员身份在 Win2012 服务器上工作。
@bendecko，您的应用程序需要管理员权限。
/!\ 不要使用此解决方案 /!\ 因为如果您使用导航（到本地文件）并且您的 html 内容位于 Intranet 区域中（例如：使用MOTW 到本地主机）。使用 99999 与使用 11000 的行为相同。要解决我上面提到的问题，您需要 11001。【参考方案4】：
我可以在 HTML 的标题中添加一行，而不是更改 RegKey：
<html>
<head>
<!-- Use lastest version of Internet Explorer -->
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<!-- Insert other header tags here -->
</head>
...
</html>
见Web Browser Control & Specifying the IE Version。
【讨论】：
虽然这种技术有效，但它不会提供相同的用户代理。使用FEATURE_BROWSER_EMULATION 技术，我得到Mozilla/5.0 (Windows NT 6.2; Win64; x64; ... 而使用X-UA-Compatible 技术，我得到Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.2; ...，Google Analytics 将其检测为移动设备。
谢谢！当您只需要托管一个本地页面时工作得非常好（因此用户代理字符串完全不相关）。【参考方案5】：
你可以试试这个link

【讨论】：
string ver = (new WebBrowser()).Version.ToString(); 好，我只是想在HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer 中检查注册表，但这种方式更简单。谢谢
Processes.getCurrentProcessName() 是什么？可能是Process.GetCurrentProcess().ProcessName？
localMachine.getOrCreateSubKey 是什么？不存在？
你也可以使用HKEY_CURRENT_USER，不需要管理员。【参考方案6】：

【参考方案7】：我能够实施 Luca 的解决方案，但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 窗体应用程序的 Web 浏览器控件一起使用（针对 .NET 2.0）。它现在对我有用。我希望这可以帮助其他人。

finally
//Close the Registry
if (Regkey != null) Regkey.Close();
另外，我在项目设置中添加了一个字符串 (ie_emulation)，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。这可以通过向您的项目中添加一个新项目来完成（使用 VS2012）。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" />
如果阅读本文的人试图将 D3.js 与网络浏览器控件一起使用，您可能必须修改 JSON 数据以存储在 HTML 页面内的变量中，因为 D3.json 使用 XmlHttpRequest（更易于与网络服务器一起使用）。在这些更改和上述更改之后，我的 Windows 窗体能够加载调用 D3 的本地 HTML 文件。

正如人们之前指出的那样，使用本地机器密钥注册限制管理员安装应用程序，而当前用户密钥允许普通用户安装应用程序。后者更灵活【参考方案9】：一种廉价且简单的解决方法是，您可以在 FEATURE_BROWSER_EMULATION 键中放置一个大于 11001 的值。然后它需要系统中可用的最新 IE。

【讨论】：
用它做什么？..如何使用它？什么时候打电话？ 如果你愿意，你可以在第一次代码午餐时调用它。使用codeInternetExplorerFeatureControl.Instance.BrowserEmulation = DocumentMode.DefaultRespectDocType;'为了更好地了解这是在哪里拉的，您可以查看msdn.microsoft.com/en-us/ie/…
还要添加注释，这个不需要管理员权限来启用。它还将根据位数选择正确的注册表并设置文档显示的相同限制。比如 GPU 渲染需要 IE 9 才能工作【参考方案13】：
最好强制使用最高模式。这可以通过添加：
<meta http-equiv="X-UA-Compatible" content="IE=edge">
为了支持 IE，最好包含 polyfill 库：
<script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>
在任何脚本之前。

【参考方案14】：现在可以使用WebView2 形式的更好解决方案。 WebView2 控件使用基于 Chromium 的 Microsoft Edge 作为呈现引擎在本机应用程序中显示 Web 内容。此控件可用于Winforms 以及WPF 应用程序中。
要在Winforms 中使用它，只需安装Microsoft.Web.WebView2 NugetPackage。之后，WebView2 将可用于您的应用程序！
