Mobile Device Detection in ASP.NET

Detect mobile device in ASP.NET Core

You can use the manual method outlined here:
https://stackoverflow.com/a/13086894/1419970

Or you can use this library: http://www.nuget.org/packages/51Degrees.mobi/3.2.10.3-beta

Both will do for you.

Asp.Net 5 MVC 6 detect mobile browser

The implementation of Request.Browser.IsMobileDevice relied on the .browser files, which AFAIK are not part of ASP.Net 5.

Let's see if someone from the team can shed some light on how they plan to implement this. There is an entry in the asp docs about mobile specific views, so they must have some plans for it.

In the meantime I guess you can create your own helper method parsing the query string, for example using the regex from detectmobilebrowsers.com. For an alternative (and less extensive) regex see detecting a mobile browser in SO.

Following this idea, a temporal solution like this extension method might help while the asp team provides their solution:

public static class RequestExtensions
{
//regex from http://detectmobilebrowsers.com/
private static readonly Regex b = new Regex(@"(android|bb\d+|meego).+mobile|avantgo|bada\/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(hone|od)|iris|kindle|lge |maemo|midp|mmp|mobile.+firefox|netfront|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)\/|plucker|pocket|psp|series(4|6)0|symbian|treo|up\.(browser|link)|vodafone|wap|windows ce|xda|xiino", RegexOptions.IgnoreCase | RegexOptions.Multiline);

public static bool IsMobileBrowser(this HttpRequest request)
{
var userAgent = request.UserAgent();
if ((b.IsMatch(userAgent) || v.IsMatch(userAgent.Substring(0, 4))))
{
return true;
}

return false;
}

public static string UserAgent(this HttpRequest request)
{
return request.Headers["User-Agent"];
}
}

Is it possible to detect the mobile device model using javascript or ASP.Net

Detecting the client reliably is not easy, but the best you can do is to look in the user agent string supplied by the client.

In ASP.NET you can access it through Request.UserAgent property.

You will have to find the exact user agents that you want to look for to identify phone models. This is for example my old Xperia Mini Pro:

Mozilla/5.0 (Linux; U; Android 2.3.4; sv-se; SonyEricssonSK17i Build/4.0.2.A.0.58) AppleWebKit/533.1 (KHTML, like Gecko) Vers

Detect mobile version in asp.net webform - c#

http://detectmobilebrowsers.com/ provide the regular expression which is quiet updated and I am using in my current project , working good. The way I have implemented is I have added HTTP Module and trap the request in BeginRequest itself . it helps me to have a single place code and can easily be part of project with update with no need to compile the whole project in case we have got the new added device in regular expression
