Asp.net discovers any tablet device with user agent string

Question

Is it possible to determine if a request comes from a tablet device (iPad, Android, etc.) with a server-side code?

EDIT: I need to know if this is an Android tablet instead of an Android phone.

From Discovery of Mobile 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); 
        }       
    }
