You can either check for Request.Browser["IsMobileDevice"] == "true" using the framework as explained here:

Or you can use 51Degrees.mobi which is shown here:

You can get UserAgent in C# using Request.UserAgent.

Try this:

string strUA = Request.UserAgent.Trim().ToLower();
bool isMobile = false;
    if (strUA .Contains("ipod") || strUA .Contains("iphone"))
        isMobile = true;

    if (strUA .Contains("android"))
        isMobile = true;

    if (strUA .Contains("opera mobi"))
        isMobile = true;

    if (strUA .Contains("windows phone os") && strUA .Contains("iemobile"))
        isMobile = true;

    if (strUA .Contains("palm")
        isMobile = true;

    bool MobileDevice = Request.Browser.IsMobileDevice;
    if(isMobile == true && MobileDevice == true)
    {
      string Url = ""; // Put your mobile site url
      Response.Redirect(Url);
    }

Note: IsMobileDevice is not actively updated with new browsers.

Some of the popular mobile devices/browsers won’t be detected using this way because ASP.NET browser files are not supported in Opera Mobile or Android devices.

As a fix of this problem is : use 51Degrees.Mobi package. 51Degrees.Mobi package

What about using a simple page, with no MasterPage, that uses Request.Browser.IsMobileDevice (or other method) to determine mobile or not and then redirect to the appropriate LogOn page for mobile or desktop?

I am also uses a querystring in the URL:

ForceMobile = Request.QueryString["ForceMobile"];
//
if (Request.Browser.IsMobileDevice || ForceMobile == "Yes")
{
    Response.Redirect("~/_Mobile/mLogOn.aspx", false);
}
else
{
    Response.Redirect("~/LogOn.aspx", false);
}

The benefits of this are ease of debugging and no post-back events caused by redirects directly in LogOn pages.
