在asp.net webform - c#中检测移动版本

我正在尝试重定向不同手机的用户&将用户引导到网站的移动版本，但由于某些原因，它似乎不起作用。

我使用以下代码

using System;
using System.Web;
using System.Web.Configuration;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
    HttpBrowserCapabilities hbc = Request.Browser;
    if (((HttpCapabilitiesBase)hbc).IsMobileDevice)
    {
        Response.Write("You are browsing from a mobile device");
    }
    else
    {
        Response.Write("No mobile device");
    }
}
}

我也看到了使用Regex的例子，可以覆盖广泛的设备。请建议推荐什么&什么作品。

String u = Request.ServerVariables["HTTP_USER_AGENT"];
     bool mobileUser = false;
                Regex b = new Regex("android.+mobile|avantgo|bada''/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(hone|od)|iris|kindle|lge |maemo|midp|mmp|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)''/|plucker|pocket|psp|symbian|treo|up''.(browser|link)|vodafone|wap|windows (ce|phone)|xda|xiino", RegexOptions.IgnoreCase | RegexOptions.Multiline);
                Regex v = new Regex("1207|6310|6590|3gso|4thp|50[1-6]i|770s|802s|a wa|abac|ac(er|oo|s''-)|ai(ko|rn)|al(av|ca|co)|amoi|an(ex|ny|yw)|aptu|ar(ch|go)|as(te|us)|attw|au(di|''-m|r |s )|avan|be(ck|ll|nq)|bi(lb|rd)|bl(ac|az)|br(e|v)w|bumb|bw''-(n|u)|c55''/|capi|ccwa|cdm''-|cell|chtm|cldc|cmd''-|co(mp|nd)|craw|da(it|ll|ng)|dbte|dc''-s|devi|dica|dmob|do(c|p)o|ds(12|''-d)|el(49|ai)|em(l2|ul)|er(ic|k0)|esl8|ez([4-7]0|os|wa|ze)|fetc|fly(''-|_)|g1 u|g560|gene|gf''-5|g''-mo|go(''.w|od)|gr(ad|un)|haie|hcit|hd''-(m|p|t)|hei''-|hi(pt|ta)|hp( i|ip)|hs''-c|ht(c(''-| |_|a|g|p|s|t)|tp)|hu(aw|tc)|i''-(20|go|ma)|i230|iac( |''-|''/)|ibro|idea|ig01|ikom|im1k|inno|ipaq|iris|ja(t|v)a|jbro|jemu|jigs|kddi|keji|kgt( |''/)|klon|kpt |kwc''-|kyo(c|k)|le(no|xi)|lg( g|''/(k|l|u)|50|54|e''-|e''/|''-[a-w])|libw|lynx|m1''-w|m3ga|m50''/|ma(te|ui|xo)|mc(01|21|ca)|m''-cr|me(di|rc|ri)|mi(o8|oa|ts)|mmef|mo(01|02|bi|de|do|t(''-| |o|v)|zz)|mt(50|p1|v )|mwbp|mywa|n10[0-2]|n20[2-3]|n30(0|2)|n50(0|2|5)|n7(0(0|1)|10)|ne((c|m)''-|on|tf|wf|wg|wt)|nok(6|i)|nzph|o2im|op(ti|wv)|oran|owg1|p800|pan(a|d|t)|pdxg|pg(13|''-([1-8]|c))|phil|pire|pl(ay|uc)|pn''-2|po(ck|rt|se)|prox|psio|pt''-g|qa''-a|qc(07|12|21|32|60|''-[2-7]|i''-)|qtek|r380|r600|raks|rim9|ro(ve|zo)|s55''/|sa(ge|ma|mm|ms|ny|va)|sc(01|h''-|oo|p''-)|sdk''/|se(c(''-|0|1)|47|mc|nd|ri)|sgh''-|shar|sie(''-|m)|sk''-0|sl(45|id)|sm(al|ar|b3|it|t5)|so(ft|ny)|sp(01|h''-|v''-|v )|sy(01|mb)|t2(18|50)|t6(00|10|18)|ta(gt|lk)|tcl''-|tdg''-|tel(i|m)|tim''-|t''-mo|to(pl|sh)|ts(70|m''-|m3|m5)|tx''-9|up(''.b|g1|si)|utst|v400|v750|veri|vi(rg|te)|vk(40|5[0-3]|''-v)|vm40|voda|vulc|vx(52|53|60|61|70|80|81|83|85|98)|w3c(''-| )|webc|whit|wi(g |nc|nw)|wmlb|wonu|x700|xda(''-|2|g)|yas''-|your|zeto|zte''-", RegexOptions.IgnoreCase | RegexOptions.Multiline);

                    {
                        mobileUser = true;
                    }
                }
                if (mobileUser) //mobile user!!
                {
                    mobileSiteUrl = ConfigurationManager.AppSettings["MobileSiteURL"];
                    Response.Redirect(mobileSiteUrl);
                }
                else
                {
                 }

您的专家视图是必需的，因为这是我的第一个移动应用
