C# 在 webbrowser 控件中使用最新版本的 Internet Explorer

Use latest version of Internet Explorer in the webbrowser control

提问by Moslem7026

The default version of the webbrowser control in a C# Windows Formsapplication is 7. I have changed to 9 by the article Browser Emulation, but how is it possible to use the latest version of the installed Internet Explorer in a webbrowser control?

C# Windows 窗体应用程序中webbrowser 控件的默认版本是 7。我已通过文章Browser Emulation更改为 9 ，但是如何在 webbrowser 控件中使用已安装 Internet Explorer 的最新版本？

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.

我看到了维尔的回答。我认为这是对的，但这不是我为我工作的。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。

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

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

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:

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：

Also, I added a string (ie_emulation) to the project's settings with the value of 11999. This value seems to be working for IE11(11.0.15).

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

Next, I had to change the permission for my application to allow access to the registry. This can be done by adding a new item to your project (using VS2012). Under the General Items, select Application Manifest File. Change the level from asInvoker to requireAdministrator (as shown below).

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添加一个新项目来完成（使用 VS2012）。在 General Items 下，选择 Application Manifest File。将级别从 asInvoker 更改为 requireAdministrator（如下所示）。

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

If someone reading this is trying to use D3.js with a webbrowser control, you may have to modify the JSON data to be stored within a variable inside your HTML page because D3.json uses XmlHttpRequest (easier to use with a webserver). After those changes and the above, my windows forms are able to load local HTML files that call D3.

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，您可能需要修改 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。

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);

According to what I read here (Controlling WebBrowser Control Compatibility:

根据我在此处阅读的内容（控制 WebBrowser 控件兼容性：

What Happens if I Set the FEATURE_BROWSER_EMULATION Document Mode Value Higher than the IE Version on the Client?

Obviously, the browser control can only support a document mode that is less than or equal to the IE version installed on the client. Using the FEATURE_BROWSER_EMULATION key works best for enterprise line of business apps where there is a deployed and support version of the browser. In the case you set the value to a browser mode that is a higher version than the browser version installed on the client, the browser control will choose the highest document mode available.

客户端设置FEATURE_BROWSER_EMULATION文档模式值高于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 键最适用于部署和支持浏览器版本的企业业务线应用程序。如果您将该值设置为高于客户端上安装的浏览器版本的浏览器模式，浏览器控件将选择可用的最高文档模式。

Rather than changing the RegKey, I was able to put a line in the header of my HTML:

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>

See Web Browser Control & Specifying the IE Version.
