comment détecter le système d'exploitation de l'utilisateur

J'ai le code suivant pour obtenir les détails de l'utilisateur:

HttpBrowserCapabilities bc = HttpContext.Current.Request.Browser;
string UserAgent = HttpContext.Current.Request.UserAgent;

ENT_TrackingData ret = new ENT_TrackingData()
{
    IPAddress = HttpContext.Current.Request.UserHostAddress,
    Browser = bc.Browser + " " + bc.Version,                
    DateStamp = DateTime.Now,
    PageViewed = HttpContext.Current.Request.Url.AbsolutePath,
    NodeId = UmbracoHelper.GetCurrentNodeID(),
    IsMobileDevice = IsMobileDevice(UserAgent),
    Platform = bc.Platform
};

Cela fonctionne très bien, mais j'ai remarqué que la plate-forme indiquait toujours que Windows NT pour ma machine, et non pas Windows 7. Est-il possible de détecter ce type d'informations dans ASP.Net?

Voici ce que je suis venu avec et cela semble fonctionner assez bien:

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;
}

Utilisez Request.UserAgent

if (Request.UserAgent.IndexOf("Windows NT 5.1") > 0)
{
//xp
}
else if (Request.UserAgent.IndexOf("Windows NT 6.0") > 0)
{
//Vista
}
else if (Request.UserAgent.IndexOf("Windows NT 6.1") > 0)
{
//7
}
else if (Request.UserAgent.IndexOf("Windows NT 6.2") > 0) 
{ 
//8
}
else if (Request.UserAgent.IndexOf("Windows NT 6.3") > 0) 
{ 
//8.1
}
else if (Request.UserAgent.IndexOf("Windows NT 10.0") > 0) 
{ 
//10

Selon Ce document Microsoft officiel nous pouvons l’utiliser pour détecter le système d’exploitation Windows:

String userAgent = Request.UserAgent;

if (userAgent.IndexOf("Windows NT 6.3") > 0)
{
    //Windows 8.1
}
else if (userAgent.IndexOf("Windows NT 6.2") > 0)
{
    //Windows 8
}
else if (userAgent.IndexOf("Windows NT 6.1") > 0)
{
    //Windows 7
}
else if (userAgent.IndexOf("Windows NT 6.0") > 0) 
{ 
    //Windows Vista
}
else if (userAgent.IndexOf("Windows NT 5.2") > 0) 
{ 
    //Windows Server 2003; Windows XP x64 Edition
}
else if (userAgent.IndexOf("Windows NT 5.1") > 0) 
{ 
    //Windows XP
}
else if (userAgent.IndexOf("Windows NT 5.01") > 0) 
{ 
    //Windows 2000, Service Pack 1 (SP1)
}
else if (userAgent.IndexOf("Windows NT 5.0") > 0) 
{ 
    //Windows 2000
}
else if (userAgent.IndexOf("Windows NT 4.0") > 0) 
{ 
    //Microsoft Windows NT 4.0
}
else if (userAgent.IndexOf("Win 9x 4.90") > 0) 
{ 
    //Windows Millennium Edition (Windows Me)
}
else if (userAgent.IndexOf("Windows 98") > 0) 
{ 
    //Windows 98
}
else if (userAgent.IndexOf("Windows 95") > 0) 
{ 
    //Windows 95
}
else if (userAgent.IndexOf("Windows CE") > 0) 
{ 
    //Windows CE
}
else
{ 
    //Others

Il existe un outil intéressant nommé: https://github.com/ua-parser/uap-csharp
qui analyse l'agent utilisateur à l'OS, au navigateur, à la version du navigateur, etc.
Lien vers Nuget

Et voici comment on l'utilise:

 public static string GetUserOS(string userAgent)
 {
    // get a parser with the embedded regex patterns
    var uaParser = Parser.GetDefault();
    ClientInfo c = uaParser.Parse(userAgent);
    return c.OS.Family;
 }

Il n'y a pas de méthode précise car toutes les informations que vous obtenez à partir des en-têtes de la demande de l'utilisateur peuvent être facilement modifiées par l'utilisateur et peuvent contenir n'importe quoi.

Si vous êtes prêt à lire des informations probablement inexactes, vous pouvez vérifier cette SO réponse à une question similaire

Utilisez le numéro de version après "Windows NT". Windows 7 a 6.1 comme numéro de version. 

Mais ne comptez pas trop sur cela, la chaîne de l'agent utilisateur est non standard . Par exemple, regardez cette liste , vous verrez que quelqu'un utilise Internet Explorer avec Windows 9.0!

John, la fonction VB est agréable, mais la ligne de Windows 10 ne fonctionne pas, car "WINDOWS" est en majuscule.

Il devrait être identique aux autres, c.-à-d.

If MyAgent.IndexOf("Windows NT 10.0") >= 0 Then
        Return "Windows 10"
