Winfrom 中完美設置webbrowser控件內核版本

前言

.NET 版本更新了一代又一代，winform中的webbrowser控件的IE內核版本卻始終用的IE7，好多網站都對IE7已經不支持。webbrowser這個控件就顯得有些雞肋，經過查找大佬門的代碼和資料，終於找到了解決辦法。這里做個記錄。

代碼實現

通用設置類：

using Microsoft.Win32;
using System;
using System.ComponentModel;

namespace Common
{
    public class SetWebBrowser
    {
        /// <summary>
        /// 修改注冊表信息來兼容當前程序
        /// </summary>
        /// <param name="ieVersion">設置IE版本</param>
        public static void SetWebBrowserFeatures(int ieVersion)
        {
            //如果在Visual Studio中運行in-proc，不要更改注冊表
            if (LicenseManager.UsageMode != LicenseUsageMode.Runtime)
                return;
            //獲取程序及名稱  
            var appName = System.IO.Path.GetFileName(System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName);
            //得到瀏覽器的模式的值  
            UInt32 ieMode = GeoEmulationModee(ieVersion);
            var featureControlRegKey = @"HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\";
            //設置瀏覽器對應用程序（appName）以什么模式（ieMode）運行  
            Registry.SetValue(featureControlRegKey + "FEATURE_BROWSER_EMULATION",
                appName, ieMode, RegistryValueKind.DWord);
            Registry.SetValue(featureControlRegKey + "FEATURE_ENABLE_CLIPCHILDREN_OPTIMIZATION",
                appName, 1, RegistryValueKind.DWord);

            //Registry.SetValue(featureControlRegKey + "FEATURE_AJAX_CONNECTIONEVENTS",  
            //    appName, 1, RegistryValueKind.DWord);  

            //Registry.SetValue(featureControlRegKey + "FEATURE_GPU_RENDERING",  
            //    appName, 1, RegistryValueKind.DWord);  

            //Registry.SetValue(featureControlRegKey + "FEATURE_WEBOC_DOCUMENT_ZOOM",  
            //    appName, 1, RegistryValueKind.DWord);  

            //Registry.SetValue(featureControlRegKey + "FEATURE_NINPUT_LEGACYMODE",  
            //    appName, 0, RegistryValueKind.DWord);  
        }
        /// <summary>  
        /// 獲取瀏覽器的版本  
        /// </summary>  
        /// <returns>返回IE版本</returns>  
        public static int GetBrowserVersion()
        {
            int browserVersion = 0;
            using (var ieKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Internet Explorer",
                RegistryKeyPermissionCheck.ReadSubTree,
                System.Security.AccessControl.RegistryRights.QueryValues))
            {
                var version = ieKey.GetValue("svcVersion");
                if (null == version)
                {
                    version = ieKey.GetValue("Version");
                    if (null == version)
                        throw new ApplicationException("Microsoft Internet Explorer is required!");
                }
                int.TryParse(version.ToString().Split('.')[0], out browserVersion);
            }
            //如果小於7  
            if (browserVersion < 7)
            {
                throw new ApplicationException("不支持的瀏覽器版本!");
            }
            return browserVersion;
        }
        /// <summary>  
        /// 通過版本得到瀏覽器模式的值  
        /// </summary>  
        /// <param name="browserVersion">瀏覽器版本</param>  
        /// <returns>瀏覽器模式值</returns>  
        public static UInt32 GeoEmulationModee(int browserVersion)
        {
            UInt32 mode = 11000; // DOCTYPE指令在IE11標准模式下顯示。.   
            switch (browserVersion)
            {
                case 7:
                    mode = 7000; //  Internet Explorer 7.   
                    break;
                case 8:
                    mode = 8000; //  Internet Explorer 8.   
                    break;
                case 9:
                    mode = 9000; // Internet Explorer 9.                      
                    break;
                case 10:
                    mode = 10000; // Internet Explorer 10.  
                    break;
                case 11:
                    mode = 11000; // Internet Explorer 11.  
                    break;
            }
            return mode;
        }
    }
}

調用：

  public partial class FrmWebBrowser : Form
    {
        public FrmWebBrowser()
        {
            InitializeComponent();
            //獲取瀏覽器版本
            int browserVersion = SetWebBrowser.GetBrowserVersion();
            //也可以直接輸入調用的版本，例如調用IE11： SetWebBrowser.SetWebBrowserFeatures(11);
            //修改注冊表兼容當前程序
            SetWebBrowser.SetWebBrowserFeatures(browserVersion);
        }    
    }
