Question

C＃Windows Forms中的Web浏览器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Web浏览器控件中使用已安装的Internet Explorer的最新版本？

Answer 1

我看到了Veer的回答。我认为这是正确的，但我并没有为我工作。也许我正在使用.NET 4并使用64x操作系统，请仔细检查。

您可以在启动应用程序时进行设置或检查：

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();
    }
}

您可以找到messagebox.show，仅用于测试。

按键如下：

11001（0x2AF9） - Internet Explorer 11.网页显示在IE11中   边缘模式，无论!DOCTYPE指令。



11000（0x2AF8） - Internet Explorer 11.包含的网页   基于标准的!DOCTYPE指令以IE11边缘模式显示。   IE11的默认值。



10001（0x2711） - Internet Explorer 10.网页以IE10标准显示   模式，不管!DOCTYPE指令。



10000（0x2710） - Internet Explorer 10.包含基于标准的网页   !DOCTYPE指令以IE10标准模式显示。默认   Internet Explorer 10的值。



9999（0x270F） - Internet Explorer 9.网页显示在IE9中   标准模式，与!DOCTYPE指令无关。



9000（0x2328） - Internet Explorer 9.包含的网页   基于标准的!DOCTYPE指令以IE9模式显示。



8888（0x22B8） - 网页以IE8标准模式显示，   无论!DOCTYPE指令。



8000（0x1F40） - 包含基于标准!DOCTYPE的网页   指令以IE8模式显示。



7000（0x1B58） - 包含基于标准!DOCTYPE的网页   指令以IE7标准模式显示。

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，以避免因注册表更改权限而导致错误：

<requestedExecutionLevel level="highestAvailable" uiAccess="false" />

更新1

这是一个类将在Windows上获取最新版本的IE并进行更改;

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);

您可能会面临Windows 10可比性的问题，可能是由于您的网站本身您可能需要添加此元标记

Answer 2

使用MSDN中的值：

  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);

Answer 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);

根据我在这里阅读的内容（Controlling WebBrowser Control Compatibility：

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键最适用于具有已部署和支持版本的浏览器的企业级业务应用程序。 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。

最简单的方法是加一个非常高的十进制数......

Answer 4

您可以尝试此link

try
{
    var IEVAlue =  9000; // can be: 9999 , 9000, 8888, 8000, 7000
    var targetApplication = Processes.getCurrentProcessName() + ".exe"; 
    var localMachine = Registry.LocalMachine;
    var parentKeyLocation = @"SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl";
    var keyName = "FEATURE_BROWSER_EMULATION";
    "opening up Key: {0} at {1}".info(keyName, parentKeyLocation);
    var subKey = localMachine.getOrCreateSubKey(parentKeyLocation,keyName,true);
    subKey.SetValue(targetApplication, IEVAlue,RegistryValueKind.DWord);
    return "all done, now try it on a new process".info();
}
catch(Exception ex)
{
    ex.log();
    "NOTE: you need to run this under no UAC".info();
}

Answer 5

我没有更改RegKey，而是在HTML的标题中添加了一行：

<html>
    <head>
        <!-- Use lastest version of Internet Explorer -->
        <meta http-equiv="X-UA-Compatible" content="IE=edge" />

        <!-- Insert other header tags here -->
    </head>
    ...
</html>

我能够实施Luca的解决方案，但我必须做一些改变才能使用它。我的目标是将D3.js与Web浏览器控件一起用于Windows窗体应用程序（面向.NET 2.0）。它现在对我有用。我希望这可以帮助别人。

using System;
using System.Collections.Generic;
using System.Windows.Forms;
using System.Threading;
using Microsoft.Win32;
using System.Diagnostics;

namespace ClientUI
{
    static class Program
    {
        static Mutex mutex = new System.Threading.Mutex(false, "jMutex");

        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            if (!mutex.WaitOne(TimeSpan.FromSeconds(2), false))
            {
                // Another application instance is running
                return;
            }
            try
            {
                Application.EnableVisualStyles();
                Application.SetCompatibleTextRenderingDefault(false);

                var targetApplication = Process.GetCurrentProcess().ProcessName + ".exe";
                int ie_emulation = 11999;
                try
                {
                    string tmp = Properties.Settings.Default.ie_emulation;
                    ie_emulation = int.Parse(tmp);
                }
                catch { }
                SetIEVersioneKeyforWebBrowserControl(targetApplication, ie_emulation);

                Application.Run(new MainForm());
            }
            finally
            {
                mutex.ReleaseMutex();
            }
        }

        private static void SetIEVersioneKeyforWebBrowserControl(string appName, int ieval)
        {
            RegistryKey Regkey = null;
            try
            {
                Regkey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", true);

                // If the path is not correct or
                // if user doesn't have privileges to access the registry
                if (Regkey == null)
                {
                    MessageBox.Show("Application FEATURE_BROWSER_EMULATION Failed - Registry key Not found");
                    return;
                }

                string FindAppkey = Convert.ToString(Regkey.GetValue(appName));

                // Check if key is already present
                if (FindAppkey == ieval.ToString())
                {
                    MessageBox.Show("Application FEATURE_BROWSER_EMULATION already set to " + ieval);
                    Regkey.Close();
                    return;
                }

                // If key is not present or different from desired, add/modify the key , key value
                Regkey.SetValue(appName, unchecked((int)ieval), RegistryValueKind.DWord);

                // Check for the key after adding
                FindAppkey = Convert.ToString(Regkey.GetValue(appName));

                if (FindAppkey == ieval.ToString())
                {
                    MessageBox.Show("Application FEATURE_BROWSER_EMULATION changed to " + ieval + "; changes will be visible at application restart");
                }
                else
                {
                    MessageBox.Show("Application FEATURE_BROWSER_EMULATION setting failed; current value is  " + ieval);
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show("Application FEATURE_BROWSER_EMULATION setting failed; " + ex.Message);
            }
            finally
            {
                //Close the Registry
                if (Regkey != null) Regkey.Close();
            }
        }
    }
}

此外，我在项目的设置中添加了一个字符串（ie_emulation），其值为11999.此值似乎适用于IE11（11.0.15）。

接下来，我必须更改应用程序的权限以允许访问注册表。这可以通过向项目添加新项目来完成（使用VS2012）。在“常规项”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" />

如果有人正在尝试将D3.js与webbrowser控件一起使用，则可能必须修改要存储在HTML页面内变量中的JSON数据，因为D3.json使用XmlHttpRequest（更容易与Web服务器一起使用））。完成上述更改后，我的Windows窗体能够加载调用D3的本地HTML文件。

Answer 8

使用：

// Get the installed Internet Explorer version
using (WebBrowser Wb = new WebBrowser())
    BrowserVer = Wb.Version.Major;

// Set the appropriate Internet Explorer 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
RegistryKey Key = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", true);
Key.SetValue(System.Diagnostics.Process.GetCurrentProcess().ProcessName + ".exe", RegVal, RegistryValueKind.DWord);
Key.Close();

Answer 9

结合RooiWillie和MohD的答案并记得以管理权限运行你的应用程序。

var appName = System.Diagnostics.Process.GetCurrentProcess().ProcessName + ".exe";

RegistryKey Regkey = null;
try
{
    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;

    //For 64 bit Machine 
    if (Environment.Is64BitOperatingSystem)
        Regkey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(@"SOFTWARE\\Wow6432Node\\Microsoft\\Internet Explorer\\MAIN\\FeatureControl\\FEATURE_BROWSER_EMULATION", true);
    else  //For 32 bit Machine 
        Regkey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(@"SOFTWARE\\Microsoft\\Internet Explorer\\Main\\FeatureControl\\FEATURE_BROWSER_EMULATION", true);

    //If the path is not correct or 
    //If user't have priviledges to access registry 
    if (Regkey == null)
    {
        MessageBox.Show("Registry Key for setting IE WebBrowser Rendering Address Not found. Try run the program with administrator's right.");
        return;
    }

    string FindAppkey = Convert.ToString(Regkey.GetValue(appName));

    //Check if key is already present 
    if (FindAppkey == RegVal.ToString())
    {
        Regkey.Close();
        return;
    }

    Regkey.SetValue(appName, RegVal, RegistryValueKind.DWord);
}
catch (Exception ex)
{
    MessageBox.Show("Registry Key for setting IE WebBrowser Rendering failed to setup");
    MessageBox.Show(ex.Message);
}
finally
{
    //Close the Registry 
    if (Regkey != null)
        Regkey.Close();
}

Answer 13

一个便宜而简单的解决方法是，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。

Answer 14

最好强制采用最高模式。可以通过添加以下内容来实现：

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

并且包含polyfill库以支持IE总是很好的做法：

<script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>

在任何脚本之前。

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 作为渲染引擎，在原生应用中显示 Web 内容。此控件可用于 Winforms 和 WPF 应用程序。

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！
