检测asp.net webform中的移动版本 – c#

我正在尝试重定向不同手机和用户的用户将用户表格移植到网站的移动版本但由于某种原因它似乎不起作用.

我正在使用以下代码

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");
    }
}
}

我还看到正在使用正则表达式的示例可能涵盖范围广泛的设备.请建议推荐的内容&什么有效.

String u = Request.ServerVariables["HTTP_USER_AGENT"];
     bool mobileUser = false;

您的专家视图是必需的,因为这是我的第一个移动应用

http://detectmobilebrowsers.com/提供正则表达式,它是安静更新的,我在我当前的项目中使用,运行良好.我实现的方式是我添加了HTTP模块并在BeginRequest本身中捕获请求.它帮助我有一个单独的地方代码,并且很容易成为项目的一部分,无需编译整个项目,以防我们在正则表达式中添加新的设备
