I would try WURFL first http://wurfl.sourceforge.net/

They have .NET API and Very good code samples. http://wurfl.sourceforge.net/dotnet_index.php

The class that will help you is called WURFLManager and has the following methods:

Use WURFL http://wurfl.sourceforge.net/dotnet_index.php

If you using asp.net mvc you can use an ActionFilter

public class MobileActionFilterAttribute : ActionFilterAttribute
{
    // The WURFL database contains information about a huge number of devices and mobile browsers.
    // http://wurfl.sourceforge.net/
    // http://wurfl.sourceforge.net/dotnet_index.php
    // http://wurfl.sourceforge.net/help_doc.php

    private static readonly IWURFLManager WurflManager;

    static MobileActionFilterAttribute ()
    {
        IWURFLConfigurer configurer = new ApplicationConfigurer();
        WurflManager = WURFLManagerBuilder.Build(configurer);
    }

    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        HttpRequestBase request = filterContext.RequestContext.HttpContext.Request;

        // We don't have ARR server for dev environment, so we still need to check to see if the current domain name is the mobile site.
        if (request.Url.AbsoluteUri.StartsWith(SiteConfiguration.Current.MobileSiteAddress, StringComparison.OrdinalIgnoreCase))
        {
            return;
        }

        // Creates a WURFLRequest object from an ASP.NET HttpRequest object
        WURFLRequest wurflRequest = WURFLRequestFactory.CreateRequest(HttpContext.Current.Request);

        // Indicates whether the current user agent string refers to a desktop agent.
        if (wurflRequest.IsDesktopRequest)
            return;

        // Get the information about the device
        IDevice deviceInfo = WurflManager.GetDeviceForRequest(wurflRequest);

        // Tells you if a device is a tablet computer (iPad and similar, regardless of OS)
        bool isTablet = string.Equals(deviceInfo.GetCapability("is_tablet") ?? string.Empty, "true", StringComparison.OrdinalIgnoreCase);

        if (isTablet)
        {
            // so we don't show the mobile site for iPad.
            return;
        }

        // Indicates whether the current user agent string refers to a mobile device.
        bool isMobileRequest = wurflRequest.IsMobileRequest;

        // Tells you if a device is wireless or not. Specifically a mobile phone or a PDA are considered wireless devices, a desktop PC or a laptop are not
        bool isWirelessDevice = string.Equals(deviceInfo.GetCapability("is_wireless_device") ?? string.Empty, "true", StringComparison.InvariantCultureIgnoreCase);

        if (isMobileRequest && isWirelessDevice)
        {
            // we can redirect to the mobile site!
            filterContext.Result = new RedirectResult(SiteConfiguration.Current.MobileSiteAddress);
        }
    }
}

There is also 51Degrees.Mobi Steve Sanderson has covered how to do this on his blog http://blog.stevensanderson.com/2010/12/17/using-51degreesmobi-foundation-for-accurate-mobile-browser-detection-on-aspnet-mvc-3/

51Degrees.Mobi Foundation is an open source .NET project that enhances Request.Browser so it gets its information from Wireless Universal Resource File (WURFL) – one of the most comprehensive and up-to-date databases of mobile device information. The great news is that 51Degrees.Mobi Foundation is now available as a NuGet package, so it’s incredibly easy to install and update.

Be careful of Windows phones! For some weird reason lots of Windows phones say "like iPhone" in the user agent. So you want to check:

public bool IsIPhone
{
    get
    {
        if (!UserAgent.ToUpper().Contains("LIKE IPHONE"))
        {
            return UserAgent.ToUpper().Contains("IPHONE");
        }
        return false;
    }
}

Example Windows phone user agent (from Lumia 735):

"Mozilla/5.0 (Mobile; Windows Phone 8.1; Android 4.0; ARM; Trident/7.0; Touch; rv:11.0; IEMobile/11.0; NOKIA; Lumia 735) like iPhone OS 7_0_3 Mac OS X AppleWebKit/537 (KHTML, like Gecko) Mobile Safari/537"

you can get client OS data from Request.UserAgent get OS name and OS version.

  public static string GetClientOS(string ua, string platform)
    {

        if (ua.Contains("Android"))
            return string.Format("Android {0}", GetMobileVersion(ua, "Android"));

        if (ua.Contains("iPad"))
            return string.Format("iPad OS {0}", GetMobileVersion(ua, "OS"));

        if (ua.Contains("iPhone"))
            return string.Format("iPhone OS {0}", GetMobileVersion(ua, "OS"));

        if (ua.Contains("Linux") && ua.Contains("KFAPWI"))
            return "Kindle Fire";

        if (ua.Contains("RIM Tablet") || (ua.Contains("BB") && ua.Contains("Mobile")))
            return "Black Berry";

        if (ua.Contains("Windows Phone"))
            return string.Format("Windows Phone {0}", GetMobileVersion(ua, "Windows Phone"));

        if (ua.Contains("Mac OS"))
            return "Mac OS";

        if (ua.Contains("Windows NT 5.1") || ua.Contains("Windows NT 5.2"))
            return "Windows XP";

        if (ua.Contains("Windows NT 6.0"))
            return "Windows Vista";

        if (ua.Contains("Windows NT 6.1"))
            return "Windows 7";

        if (ua.Contains("Windows NT 6.2"))
            return "Windows 8";

        if (ua.Contains("Windows NT 6.3"))
            return "Windows 8.1";

        if (ua.Contains("Windows NT 10"))
            return "Windows 10";

        return  platform + (ua.Contains("Mobile") ? " Mobile " : "");
    }

    public static string GetMobileVersion(string userAgent, string device)
    {
        var temp = userAgent.Substring(userAgent.IndexOf(device) + device.Length).TrimStart();
        var version = string.Empty;

        foreach (var character in temp)
        {
            var validCharacter = false;
            int test = 0;

            if (int.TryParse(character.ToString(), out test))
            {
                version += character;
                validCharacter = true;
            }

            if (character == '.' || character == '_')
            {
                version += '.';
                validCharacter = true;
            }

            if (validCharacter == false)
                break;
        }

        return version;
    }
