asp.net 检测任何带有用户代理字符串的平板电脑设备

Question

是否可以使用服务器端代码检测请求是否来自平板电脑设备(iPad、Android 等)？

编辑:我需要知道它是否是 Android 平板电脑而不是 Android 手机。

来自Detecting mobile device user agents in ASP.NET (Android) :

 //for Mobile device 
    protected override void OnInit(EventArgs e) 
    { 

        string userAgent = Request.UserAgent; 
        if (userAgent.Contains("BlackBerry") 
          || (userAgent.Contains("iPhone") || (userAgent.Contains("Android")))) 
        { 
            //add css ref to header from code behind 
            HtmlLink css = new HtmlLink(); 
            css.Href = ResolveClientUrl("~/mobile.css"); 
            css.Attributes["rel"] = "stylesheet";  
            css.Attributes["type"] = "text/css";  
            css.Attributes["media"] = "all";  
            Page.Header.Controls.Add(css); 
        }       
    }
