.net核心中无法进行本地化，未设置默认区域性

Question

嗨，我正在尝试在.net core中实现本地化。我想在我的视图静态内容中实现本地化。默认情况下，它将显示德语，也可以更改为其他语言。我已将其配置为将默认区域性设置为德语，但无法正常工作。请帮助

我尝试过的是：-

在我的启动文件中

public void ConfigureServices(IServiceCollection services)
        {

            //adding HttpContextAccessor middleware
            services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();

        services.AddRouting(options => options.LowercaseUrls = true);
        services.AddMvc();

        //configuration for multilanguage support
        services.AddLocalization();

        services.AddMvc()
 .AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix)
 .AddDataAnnotationsLocalization();



        //adding other services...
        ConfigureBusinessServices(services);
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        var supportedCultures = new[]{
      new CultureInfo("en-US"),
      new CultureInfo("fr"),
      new CultureInfo("de"),

        };

        app.UseRequestLocalization(new RequestLocalizationOptions
        {
            DefaultRequestCulture = new RequestCulture("de"),
            // Formatting numbers, dates, etc.
            SupportedCultures = supportedCultures,
            // UI strings that we have localized.
            SupportedUICultures = supportedCultures
        });


        app.UseStaticFiles();
        app.UseSession();

        //configuring mvc routes...
        app.UseMvc(routes =>
        {
            routes.MapRoute(
               name: "areaRoute",
               template: "{area:exists}/{controller}/{action}/{id?}",
               defaults: new { controller = "Home", action = "Index" });

            routes.MapRoute(
                name: "default",
                template: "{controller}/{action}/{id?}",
                defaults: new { controller = "Home", action = "Index" });
        });
    }

在我看来，我已经做到了：-

@TestProject.Resources.TestProjectUI.Home.ContactUs.btn_TextSendMessage

显示资源价值

我正在从资源文件中获取数据，但从英语资源文件中获取数据，因为当前的文化设置为英语英国。我得到这样的输出：

当前的区域性显示为英语，因为消息（发送消息英语区域性）来自En.resx文件。
