推荐答案

我看到了 Veer 的回答.我认为这是对的，但这不是我为我工作的.也许我使用的是 .NET 4 并且使用的是 64x 操作系统，所以请检查这个.

I saw Veer's answer. I think it's right, but it did not I work for me. Maybe I am using .NET 4 and am using 64x OS so kindly check this.

您可以在应用程序启动时进行设置或检查:

You may put in setup or check it in start-up of your application:

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();
    }
}

你可能会找到 messagebox.show，只是为了测试.

You may find messagebox.show, just for testing.

参考:MSDN:互联网功能控制

我看到像 Skype 这样的应用程序使用 10001.我不知道.

I saw applications like Skype use 10001. I do not know.

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中的权限更改而导致的错误:

The setup application will change the registry. You may need to add a line in the Manifest File to avoid errors due to permissions of change in registry:

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

更新 1

这是一个将在 Windows 上获取最新版本的 IE 并按原样进行更改的类；

This is a class will get the latest version of IE on windows and make changes as should be;

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 + @"SoftwareWow6432NodeMicrosoftInternet ExplorerMainFeatureControlFEATURE_BROWSER_EMULATION", appName, ieVer);
            else  //For 32 bit Machine 
                Microsoft.Win32.Registry.SetValue(root + @"SoftwareMicrosoftInternet ExplorerMainFeatureControlFEATURE_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 = @"HKLMSOFTWAREMicrosoftInternet Explorer";
        string strKeyPath = @"HKEY_LOCAL_MACHINESOFTWAREMicrosoftInternet 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);

您可能会遇到与 Windows 10 相比的问题，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

you may face a problem for in comparability of windows 10, may due to your website itself you may need to add this meta tag

<meta http-equiv="X-UA-Compatible" content="IE=11" >
