public bool isMobileBrowser()

    //GETS THE CURRENT USER CONTEXT
    HttpContext context = HttpContext.Current;

    //FIRST TRY BUILT IN ASP.NT CHECK
    if (context.Request.Browser.IsMobileDevice)

        return true;
    }
    //THEN TRY CHECKING FOR THE HTTP_X_WAP_PROFILE HEADER

    if (context.Request.ServerVariables["HTTP_ACCEPT"] != null &&
        context.Request.ServerVariables["HTTP_ACCEPT"].ToLower().Contains("wap"))
    {

        //Loop through each item in the list created above
        //and check if the header contains that text
        foreach (string s in mobiles)

                                                ToLower().Contains(s.ToLower()))
            {
                return true;
            }
        }
    }

    return false;
}

You can call this function as:

if (isMobileBrowser() == true)
{
 //code for mobile browser
}
else {
   //code for desktop browser
}
