how can check if user platform is windows in asp.net mvc

Question

how can check if user platform is windows or web or android or IOS in asp.net mvc?

I think we can use something like

Request.Browser.Platform

but don't know how can check user platform specially when platform is windows (I mean desctop application not web or mobile)

thanks

I tried this code

      var Agent = Request.UserAgent;


        if (Agent.ToLower().Contains("windows"))
        {
            return "WINDOWS";
        }
        else if (Agent != null && (Agent.ToLower().Contains("android")))
        {
            return "ANDROID";
        }
        else if (Agent != null && (Agent.ToLower().Contains("ios")))
        {
            return "IOS";
        }
        else
        {
            return "WEB";
        }

but when I test it using locallhost it returns windows not web what's wront here?

You're probably not going to be able to determine anything outside of the information the browser they are using can give you - probably via the UserAgent signature.

Using C# you can't, C# runs on the server. The HTTP request doesn't contain this information. [Javascript can determine some information which you could then send to the server](https://stackoverflow.com/questions/9514179/how-to-find-the-operating-system-version-using-javascript) — Liam, Oct 03 '18 at 10:45

public String GetUserEnvironment(HttpRequest request)
{
    var browser = request.Browser;
    var platform = GetUserPlatform(request);
    return string.Format("{0} {1} / {2}", browser.Browser, browser.Version, platform);
}

public String GetUserPlatform(HttpRequest request)
{
    var ua = request.UserAgent;

    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";

    //fallback to basic platform:
    return request.Browser.Platform + (ua.Contains("Mobile") ? " Mobile " : "");
}

public 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 (Int32.TryParse(character.ToString(), out test))
        {
            version += character;
            validCharacter = true;
        }

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

        if (validCharacter == false)
            break;
    }

    return version;
}
