Winform中使用 webbrowser设置 IE版本

//如果电脑上安装了IE8或者之后版本的IE浏览器，Webbrowser控件会使用IE7兼容模式来显示网页内容。解决方法是在注册表中为你的进程指定引用IE的版本号。
//比如我的程序叫做a.exe
//对于32位程序
//HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION
//对于64位程序
//HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION
//在对应的路径下添加你程序名字，如a.exe为名的value，DWORD值。
//值选项：
//10000(0×2710) IE10
//9999 (0x270F) IE9 忽略html5
//9000 (0×2328) IE9
//8888 (0x22B8) IE8 忽略html5
//8000 (0x1F40) IE8
//7000 (0x1B58) IE7


/// <summary>
/// 获取操作系统位数
/// </summary>
/// <returns></returns>
private string OSBit()
{
    try
    {
        ConnectionOptions oConn = new ConnectionOptions();
        System.Management.ManagementScope managementScope = new System.Management.ManagementScope("\\\\localhost", oConn);
        System.Management.ObjectQuery objectQuery = new System.Management.ObjectQuery("select AddressWidth from Win32_Processor");
        ManagementObjectSearcher moSearcher = new ManagementObjectSearcher(managementScope, objectQuery);
        ManagementObjectCollection moReturnCollection = null;
        string addressWidth = null;
        moReturnCollection = moSearcher.Get();
        foreach (ManagementObject oReturn in moReturnCollection)
        {
            addressWidth = oReturn["AddressWidth"].ToString();
        }
        return addressWidth;
    }
    catch
