¿Cómo detecto el sistema operativo del usuario?

Question

Tengo el siguiente código para obtener detalles del usuario:

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
};

Esto funciona muy bien pero noté que la Plataforma siempre dice Windows NT para mi máquina, no Windows 7. ¿Hay alguna forma de detectar este tipo de información en ASP.Net?

Answer 1

Esto es lo que se me ocurrió y parece funcionar bastante 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;
}

Answer 2

Hay una herramienta genial llamada: https://github.com/ua-parser/uap-csharp
que analiza el agente de usuario para el sistema operativo, el navegador, la versión del navegador, etc.
Enlace a Nuget

Y así es como se usa:

 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;
}

Answer 3

La función VB de John es buena, pero la línea para Windows 10 no funciona porque tiene "WINDOWS" en mayúsculas.

Debe ser igual a los demás, es decir

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

Answer 4

La respuesta de VB.NET: Lo incluyo solo porque puede ser más fácil de leer y entender.

Public Function GetOS() As String
Dim MyAgent As String = Current.Request.UserAgent
If MyAgent.IndexOf("Windows NT 10.0") >= 0 Then
Return "Windows 10"
ElseIf MyAgent.IndexOf("Windows NT 6.3") >= 0 Then
Return "Windows 8.1"
ElseIf MyAgent.IndexOf("Windows NT 6.2") >= 0 Then
Return "Windows 8"
ElseIf MyAgent.IndexOf("Windows NT 6.1") >= 0 Then
Return "Windows 7"
ElseIf MyAgent.IndexOf("Windows NT 6.0") >= 0 Then
Return "Windows Vista"
ElseIf MyAgent.IndexOf("Windows NT 5.2") >= 0 Then
Return "Windows Server 2003"
ElseIf MyAgent.IndexOf("Windows NT 5.1") >= 0 Then

Return "Windows ME"
ElseIf MyAgent.IndexOf("Windows 98") >= 0 Then
Return "Windows 98"
ElseIf MyAgent.IndexOf("Windows 95") >= 0 Then
Return "Windows 95"
ElseIf MyAgent.IndexOf("Windows CE") >= 0 Then
Return "Windows CE"
ElseIf (MyAgent.Contains("iPad")) Then
Return String.Format("iPad OS {0}", GetMobileVersion(MyAgent, "OS"))
ElseIf (MyAgent.Contains("iPhone")) Then
Return String.Format("iPhone OS {0}", GetMobileVersion(MyAgent, "OS"))
ElseIf (MyAgent.Contains("Linux") AndAlso MyAgent.Contains("KFAPWI")) Then
Return "Kindle Fire"
ElseIf (MyAgent.Contains("RIM Tablet") OrElse (MyAgent.Contains("BB") AndAlso MyAgent.Contains("Mobile"))) Then
Return "Black Berry"
ElseIf (MyAgent.Contains("Windows Phone")) Then
Return String.Format("Windows Phone {0}", GetMobileVersion(MyAgent, "Windows Phone"))
ElseIf (MyAgent.Contains("Mac OS")) Then
Return "Mac OS"
ElseIf MyAgent.IndexOf("ANDROID") >= 0 Then
Return String.Format("Android {0}", GetMobileVersion(MyAgent, "ANDROID"))
Else
Return "OS is unknown."
End If
End Function
Private Function GetMobileVersion(userAgent As String, device As String) As String
Dim ReturnValue As String = String.Empty
Dim RawVersion As String = userAgent.Substring(userAgent.IndexOf(device) + device.Length).TrimStart()
For Each character As Char In RawVersion
If IsNumeric(character) Then
ReturnValue &= character
ElseIf (character = "." OrElse character = "_") Then
ReturnValue &= "."
Else
Exit For
End If
Next
Return ReturnValue
End Function

Answer 5

No hay una forma precisa de hacerlo, ya que toda la información que obtiene de los encabezados de solicitud del usuario puede cambiarla fácilmente y puede contener cualquier cosa.

Si está de acuerdo con la lectura de información probablemente inexacta, es posible que desee consultar esta respuesta SO a una pregunta similar

Answer 6

Prueba esto solo lo modifico

string device = getOSInfo();
public String getOSInfo()
{
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 (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;

Answer 7

Según este documento oficial de Microsoft , podemos usarlo para detectar el sistema operativo 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
}

Answer 8

Use 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
}

Answer 9

Utilice el número de versión después de "Windows NT". Windows 7 tiene 6.1 como número de versión.

Pero no confíe demasiado en eso, la cadena de agente de usuario no es estándar. Por ejemplo, mira esta lista , verás que alguien está utilizando Internet Explorer con Windows 9.0.

Uso

var os = new OS();
os.os_name; // here is os name
os.os_version; // here is os vers

Answer 11

private string getOS()
{
string os = null;
if (Request.UserAgent.IndexOf("Windows NT 5.1") > 0)
{
os ="Windows XP";
return os;
}
else if (Request.UserAgent.IndexOf("Windows NT 6.0") > 0)
{
os= "Windows Vista";
return os;
}
else if (Request.UserAgent.IndexOf("Windows NT 6.1") > 0)
{
os = "Windows 7";
return os;
}
else if (Request.UserAgent.IndexOf("Intel Mac OS X") > 0)
{
//os = "Mac OS or older version of Windows";
