C# IE环境 - 重置IE（ 注册表）

IE设置，都可以通过注册表，修改。以下是一些常用的IE设置注册表修改~

检查证书吊销

     /// <summary>
     /// 检查证书是否吊销
     /// </summary>
     /// <param name="isOpen"></param>
     public void SetCertificateVerificationState(bool isOpen)
     {
         //检查发行商的证书是否吊销
         //0 开启，512 取消
         var softwarePublishing = @"Software\Microsoft\Windows\CurrentVersion\WinTrust\Trust Providers\Software Publishing";
         RegistryHelper.ModifyCurrentUserRegistryKey(softwarePublishing, "State", isOpen ? "" : "512 ");

         //检查服务器证书吊销
         //1开启，0关闭
         var internetSettings = @"Software\Microsoft\Windows\CurrentVersion\Internet Settings";
         RegistryHelper.ModifyCurrentUserRegistryKey(internetSettings, "CertificateRevocation", isOpen ? "" : "");
     }

SSL & TSL是否勾选

     /// <summary>
     /// 设置SSLAndTSL
     /// </summary>
     /// <param name="isOpen"></param>
     public void SetSSLAndTSLState(bool isOpen)
     {
         //使用SSL3.0和TLS1.0
         var internetSettings = @"Software\Microsoft\Windows\CurrentVersion\Internet Settings";
         RegistryHelper.ModifyCurrentUserRegistryKey(internetSettings, "SecureProtocols", isOpen ? "" : "");
     }

修改IE安全等级

     /// <summary>
     /// 修改IE安全等级为中
     /// </summary>
     public void SetInternetProtectLevelNormal()
     {         //"CurrentLevel"=dword:00011000
         //"MinLevel" = dword:00011000
         //"RecommendedLevel" = dword:00011000
         var internetSettings = @"HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3";
         RegistryHelper.ModifyCurrentUserRegistryKey(internetSettings, "CurrentLevel", "");
         RegistryHelper.ModifyCurrentUserRegistryKey(internetSettings, "MinLevel", "");
         RegistryHelper.ModifyCurrentUserRegistryKey(internetSettings, "RecommendedLevel", "");
     }

注册表修改：

     public static bool ModifyCurrentUserRegistryKey(string registerPath, string key, string value)
     {
         RegistryKey currentUserKey = null;
         RegistryKey subKey = null;
         try
         {
             currentUserKey = Registry.CurrentUser;
             subKey = GetSubKey(currentUserKey, registerPath);

             if (subKey != null)
             {
                 subKey.SetValue(key, value, RegistryValueKind.DWord);
                 subKey.Close();
                 subKey.Dispose();
             }
         }
         catch (Exception e)
         {
             subKey?.Close();
             subKey?.Dispose();
             return false;
         }
         currentUserKey?.Close();
         currentUserKey?.Dispose();
         return true;
     }

     private static RegistryKey GetSubKey(RegistryKey currentUserKey, string registerPath)
     {
         RegistryKey subKey;
         subKey = currentUserKey.OpenSubKey(registerPath, true);
         if (subKey == null)
         {
             subKey = currentUserKey.CreateSubKey(registerPath, RegistryKeyPermissionCheck.ReadWriteSubTree);
         }

         return subKey;
     }

重置IE - 删除IE全部注册表

也可以通过删除注册表下，IE整个注册表项，来重置IE环境。

1     /// <summary>
2     /// 重置IE浏览器
3     /// </summary>
4     public void ResetInternetSetting()
5     {
6         var internetSettings = @"Software\Microsoft\Internet Explorer";
7         RegistryHelper.DeleteCurrentUserRegistryPath(internetSettings);
8     }

 1     public bool DeleteCurrentUserRegistryPath(string registerPath)
 2     {
 3         RegistryKey currentUserKey = null;
 4         try
 5         {
 6             currentUserKey = Registry.CurrentUser;
 7             currentUserKey.DeleteSubKey(registerPath, false);
 8         }
 9         catch (Exception e)
10         {
11             return false;
12         }
13         currentUserKey?.Close();
14         currentUserKey?.Dispose();
15         return true;
16     }
