Detect requesting device type and redirect in ASP.NET and JQuery, Java script

In ASP.NET WebForms we have an option to check whether the requested device is Mobile or not – Request.IsMobileDevice, which is not appropriate in most of the scenarios! I mean, it’s failing to detect the device type correctly!
Now, we discuss about custom solution for ASP.NET WebForms – detect the device type and redirecting!
Suppose if you have two versions of your web application – Mobile & Desktop, and you may wish to get the device information  and redirect the user to the appropriate web app based on the requested device

    private string DeviceName()
    {
        string DeviceName = "Other"; // Desktop
        string[] MobileDevices = new string[] { "iPhone", "iPad","iPod","BlackBerry",
                                                     "Nokia", "Android", "WindowsPhone",
                                                     "Mobile"
                                                     };
        foreach (string MobileDeviceName in MobileDevices)
        {
            if ((Request.UserAgent.IndexOf(MobileDeviceName, StringComparison.OrdinalIgnoreCase)) > 0)
            {
                DeviceName = MobileDeviceName;
                break;

            }
        }//end:foreach loop

        return DeviceName;
    }

if (DeviceName() == "Android")
        {
            //Response.Redirect("Mobile/Home.aspx");
            lblMesage.Text = "Mobile Device    " + DeviceName();
        }
        else
        {
            //Response.Redirect("Desktop/Home.aspx");
            lblMesage.Text = "other device";
        }
==================================

in Javascript 

 $(document).ready(function () {           
            var ua = navigator.userAgent.toLowerCase();
            var isAndroid = ua.indexOf("android") > -1; //&& ua.indexOf("mobile");
            if (isAndroid) {
                 window.location= "http://www.murlid05.blogspot.com";
            }
});
