Winform设置WebBowser访问网页内核版本
我们如果使用Winform打开网页,经常会碰到网页报错的问题,大多数情况是浏览器兼容的原因,我们可以通过设置更高版本的浏览器内核来规避。
整体思路:修改注册表信息来设置当前应用程序程序兼容的IE版本。
封装了一个通用类WebBrowserHelper:
using Microsoft.Win32; using System; using System.Collections.Generic; using System.ComponentModel; using System.Linq; using System.Text; using System.Threading.Tasks; namespace Helper { public class WebBrowserHelper { /// <summary> /// 修改注册表信息来兼容当前程序 /// </summary> public static void SetWebBrowserFeatures(int ieVersion) { // don't change the registry if running in-proc inside Visual Studio if (LicenseManager.UsageMode != LicenseUsageMode.Runtime) return; //获取程序及名称 var appName = System.IO.Path.GetFileName(System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName); //得到浏览器的模式的值 UInt32 ieMode = GeoEmulationModee(ieVersion); var featureControlRegKey = @"HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\"; //设置浏览器对应用程序(appName)以什么模式(ieMode)运行 Registry.SetValue(featureControlRegKey + "FEATURE_BROWSER_EMULATION", appName, ieMode, RegistryValueKind.DWord); // enable the features which are "On" for the full Internet Explorer browser //不晓得设置有什么用 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> /// 获取浏览器的版本 /// </summary> /// <returns></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); } //如果小于7 if (browserVersion < 7) { throw new ApplicationException("不支持的浏览器版本!"); } return browserVersion; } /// <summary> /// 通过版本得到浏览器模式的值 /// </summary> /// <param name="browserVersion"></param> /// <returns></returns> public static UInt32 GeoEmulationModee(int browserVersion) { UInt32 mode = 11000; // Internet Explorer 11. Webpages containing standards-based !DOCTYPE directives are displayed in IE11 Standards mode. switch (browserVersion) { case 7: mode = 7000; // Webpages containing standards-based !DOCTYPE directives are displayed in IE7 Standards mode. break; case 8: mode = 8000; // Webpages containing standards-based !DOCTYPE directives are displayed in IE8 mode. break; case 9: mode = 9000; // Internet Explorer 9. Webpages containing standards-based !DOCTYPE directives are displayed in IE9 mode. break; case 10: mode = 10000; // Internet Explorer 10. break; case 11: mode = 11000; // Internet Explorer 11 break; } return mode; } } }
调用方法:
this.webBrowser1.Size = new Size(1920, 1080); WebBrowserHelper.SetWebBrowserFeatures(11);//内核设为IE11 this.webBrowser1.Navigate("要跳转的链接地址");
