Get browser language in .AspNetCore2.0?

I am trying to get the default language from the browser and I use the following code to get it:

var languages = HttpContext.Request.UserLanguages;

Since the above is not supported with .NET Core 2 I tested with:

var requestContext = Request.HttpContext.Features.Get<IRequestCultureFeature>();

However, it returns null. What is the correct way or alternative to get the language?

IRequestCultureFeature provides the first matched language, which is supported by your application. Declaration of supported languages is defined in Configure() of your Startup class (see example). If you still need all accepted languages as a simple string[] like the older Request.UserLanguages property, then use the HeaderDictionaryTypeExtensions.GetTypedHeaders() extension defined in the Microsoft.AspNetCore.Http namespace:

// In your action method.
var languages = Request.GetTypedHeaders()
                       ?.OrderByDescending(x => x.Quality ?? 1) // Quality defines priority from 0 to 1, where 1 is the highest.
                       .Select(x => x.Value.ToString())
                       .ToArray() ?? Array.Empty<string>();

The array languages contains the list of accepted languages according to the priority parameter q. The language with the highest priority comes first. To get the default language take the first element of the array languages.

As an extension method:

using System.Collections.Generic;
using System.Linq;

using Microsoft.AspNetCore.Http;

public static class HttpRequestExtensions
    public static string[] GetUserLanguages(this HttpRequest request)
        return request.GetTypedHeaders()
            ?.OrderByDescending(x => x.Quality ?? 1)
            .Select(x => x.Value.ToString())
            .ToArray() ?? Array.Empty<string>();

You need to add the localisation middleware to be able to get the IRequestCultureFeature feature:

public void Configure(IApplicationBuilder app)

    //Add this:


Now in your controller you can request the feature like this:

var requestCulture = Request.HttpContext.Features.Get<IRequestCultureFeature>();

The Accept-Language HTTP header from a browser request isn't an infallible way to detect the user's preferred language (see Setting language preferences in a browser).

You can get the browser language from the Request Headers

Write on your controller:

//For example --> browserLang = 'en-US'
var browserLang= Request.Headers["Accept-Language"].ToString().Split(";").FirstOrDefault()?.Split(",").FirstOrDefault();

Globalization and localization in ASP.NET Core, Gets a sorted string array of client language preferences. public string[] UserLanguages { get; } The language names are provided by the browser, and there is no definitive list of all UserLanguages; for (count = 0; count < userLang. Full sample solution built on ASP.NET Core 2.0 for this blog post is available at GitHub repository gpeipman/AspNetCoreLocalization. My scenario was simple: We have limited number of supported languages and the number of languages doesn’t change often; Coming of new language means changes in organization and it will probably be high level

You have to add the localization middleware to enable parsing of the culture header, and then get the value through IRequestCultureFeature.

  • Have you added the localisation middleware?
  • Upvoting. I don't see why someone downvoted it because this is a good answer
  • @JérômeMEVEL downvote might be revenge, because I downvoted the accepted answer.
  • It is not answer. IRequestCultureFeature is not string[].
  • @EvgeniNabokov Of course it isn't a string, it's a service that implements the IRequestCultureFeature interface, exactly as OP uses in the question. OP thought it was correct and accepted is as such, so thank you for the downvote!
  • @DavidG How to get the list of accepted languages using this feature? I used to use Request.UserLanguages which is string[].
  • @EvgeniNabokov Like I said above, use the requestCulture object. So something like var requestedCulture = requestCulture.RequestCulture;
  • @DavidG First, from your example is not clear how to get any language from IRequestCultureFeature. Provide more informative example, please. Second, IRequestCultureFeature is not replace for UserLanguages. I have interfaces that consume user languages as string[]. I can't change interfaces and I can't just create an 1-element array from Culture or UICulture (which matches the first supported language), because I need all accepted languages to pass them further. I came to conclusion I have to parse the accept-languages header manually (as written by Carlos Tenorio). That's sad.
  • Discarding the priority parameter "q" is a bad idea.
