C# IE环境

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 = @"SoftwareMicrosoftWindowsCurrentVersionWinTrustTrust ProvidersSoftware Publishing";
        RegistryHelper.ModifyCurrentUserRegistryKey(softwarePublishing, "State", isOpen ? "0" : "512 ");

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

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 = @"SoftwareMicrosoftWindowsCurrentVersionInternet Settings";
        RegistryHelper.ModifyCurrentUserRegistryKey(internetSettings, "SecureProtocols", isOpen ? "2688" : "0");
    }

修改IE安全等级

    /// <summary>
    /// 修改IE安全等级为中
    /// </summary>
    public void SetInternetProtectLevelNormal()
    { 7         //"CurrentLevel"=dword:00011000
        //"MinLevel" = dword:00011000
        //"RecommendedLevel" = dword:00011000
        var internetSettings = @"HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionInternet Settingsones3";
        RegistryHelper.ModifyCurrentUserRegistryKey(internetSettings, "CurrentLevel", "00011000");
        RegistryHelper.ModifyCurrentUserRegistryKey(internetSettings, "MinLevel", "00011000");
        RegistryHelper.ModifyCurrentUserRegistryKey(internetSettings, "RecommendedLevel", "00011000");
    }

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 = @"SoftwareMicrosoftInternet 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     }
