I have the following code to obtain user details:
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
};
This works great but I noticed that the Platform always says windows NT for my machine not Windows 7. Is there any way to detect this type of information in ASP.Net?
Here's what I came up with and it seems to work fairly well:
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;
}
