Force locale with Asp.Net Core

Force locale with Asp.Net Core

In Asp.Net Core, you can force a specific locale (i.e., language and culture) by using middleware to modify the CultureInfo and UICulture properties of the current Thread. Here's an example of how you can do this:

using System.Globalization; using System.Threading.Tasks; using Microsoft.AspNetCore.Http; public class ForceLocaleMiddleware { private readonly RequestDelegate _next; private readonly string _locale; public ForceLocaleMiddleware(RequestDelegate next, string locale) { _next = next; _locale = locale; } public async Task Invoke(HttpContext context) { var cultureInfo = new CultureInfo(_locale); CultureInfo.CurrentCulture = cultureInfo; CultureInfo.CurrentUICulture = cultureInfo; await _next(context); } }

In this example, we're creating a middleware class called ForceLocaleMiddleware that takes a locale as a constructor parameter. In the Invoke method, we create a new CultureInfo object with the specified locale, and then set the CurrentCulture and CurrentUICulture properties of the current thread to the new CultureInfo. We then call the next middleware in the pipeline using the await _next(context) statement.

To use this middleware, you would add it to the middleware pipeline in the Configure method of your Startup class. Here's an example:

public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { app.UseMiddleware<ForceLocaleMiddleware>("fr-FR"); // other middleware... }

In this example, we're adding the ForceLocaleMiddleware to the middleware pipeline with a locale of "fr-FR". This means that any requests processed by this middleware and subsequent middleware in the pipeline will have their CultureInfo and UICulture properties set to the French (France) culture.

Examples

  1. "ASP.NET Core force specific culture"

    • Code Implementation:
      // Configure in Startup.cs app.UseRequestLocalization(new RequestLocalizationOptions { DefaultRequestCulture = new RequestCulture("en-US"), SupportedCultures = new List<CultureInfo> { new CultureInfo("en-US") }, SupportedUICultures = new List<CultureInfo> { new CultureInfo("en-US") } });
    • Description: Forces the application to use the "en-US" culture as the default and only supported culture.

  2. "ASP.NET Core set current culture"

    • Code Implementation:
      // In a controller action or middleware CultureInfo.CurrentCulture = new CultureInfo("fr-FR");
    • Description: Sets the current culture to "fr-FR" for a specific request or middleware.

  3. "ASP.NET Core force culture with attribute"

    • Code Implementation:
      [MiddlewareFilter(typeof(LocalizationPipeline))] public class MyController : Controller { // Controller actions } 
      public class LocalizationPipeline { public void Configure(IApplicationBuilder app) { app.UseRequestLocalization(new RequestLocalizationOptions { DefaultRequestCulture = new RequestCulture("es-ES"), SupportedCultures = new List<CultureInfo> { new CultureInfo("es-ES") }, SupportedUICultures = new List<CultureInfo> { new CultureInfo("es-ES") } }); } }
    • Description: Forces the culture for a specific controller using a custom middleware.

  4. "ASP.NET Core set culture in Razor view"

    • Code Implementation:
      @CultureInfo.CurrentCulture = new CultureInfo("de-DE");
    • Description: Sets the culture directly in a Razor view.

  5. "ASP.NET Core change culture on user login"

    • Code Implementation:
      // In a user login logic var user = // Retrieve user information CultureInfo.CurrentCulture = new CultureInfo(user.PreferredCulture);
    • Description: Changes the user's culture upon login based on their preference.

  6. "ASP.NET Core set culture in middleware"

    • Code Implementation:
      // In Startup.cs app.Use(async (context, next) => { CultureInfo.CurrentCulture = new CultureInfo("it-IT"); await next(); });
    • Description: Sets the culture for all requests in a middleware.

  7. "ASP.NET Core force specific culture for API"

    • Code Implementation:
      // In Startup.cs services.Configure<RequestLocalizationOptions>(options => { options.DefaultRequestCulture = new RequestCulture("ja-JP"); options.SupportedCultures = new List<CultureInfo> { new CultureInfo("ja-JP") }; options.SupportedUICultures = new List<CultureInfo> { new CultureInfo("ja-JP") }; });
    • Description: Forces a specific culture for API requests using RequestLocalizationOptions.

  8. "ASP.NET Core force culture in attribute routing"

    • Code Implementation:
      [Route("api/{culture:regex(^[a-z]{{2}}-[A-Z]{{2}}$)}/[controller]")] public class MyApiController : ControllerBase { // API actions }
    • Description: Enforces a specific culture as part of the attribute routing for an API controller.

  9. "ASP.NET Core force culture for specific area"

    • Code Implementation:
      // In Startup.cs services.Configure<RequestLocalizationOptions>(options => { options.RequestCultureProviders.Insert(0, new RouteValueRequestCultureProvider { RouteDataStringKey = "area", Options = options }); options.DefaultRequestCulture = new RequestCulture("fr-FR"); options.SupportedCultures = new List<CultureInfo> { new CultureInfo("fr-FR") }; options.SupportedUICultures = new List<CultureInfo> { new CultureInfo("fr-FR") }; });
    • Description: Forces a specific culture for requests within a designated area using RouteValueRequestCultureProvider.

  10. "ASP.NET Core force culture for specific page"

    • Code Implementation:
      // In a Razor page @page Culture="es-ES"
    • Description: Sets the culture for a specific Razor page using the Culture attribute in the page directive.
