在 Asp.net Core 中设置 CultureInfo 以获得 .作为CurrencyDecimalSeparator 而不是 ,

我要疯了。我只是希望将整个 Asp.net core 应用程序中使用的区域性设置为“en-US”。但似乎没有任何作用。在哪里设置整个应用程序的文化？我对客户端浏览器文化之类的不感兴趣。唯一改变它的似乎是更改 Windows 的语言设置。我只是希望文化由应用程序本身决定，而不是由客户决定。

到目前为止我已经尝试过：

• Set <system.web><globalization uiCulture="en" culture="en-US" /></system.web>在 web.config 中
• Set System.Threading.Thread.CurrentThread.CurrentCulture = cultureInfo; and CurrentUICulture在 Startup.Configure 甚至控制器中。

• Use app.UseRequestLocalization(..如下所示

      var enUsCulture = new CultureInfo("en-US");
      var localizationOptions = new RequestLocalizationOptions()
      {
          SupportedCultures = new List<CultureInfo>()
          {
              enUsCulture
          },
          SupportedUICultures = new List<CultureInfo>()
          {
              enUsCulture
          },
          DefaultRequestCulture = new RequestCulture(enUsCulture),
          FallBackToParentCultures = false,
          FallBackToParentUICultures = false,
          RequestCultureProviders = null
      };
  
      app.UseRequestLocalization(localizationOptions);
  

但似乎没有什么可以将CurrencyDecimalSeparator从 (nl-NL) 更改为 (en-US) 。

文化如何设定？

EDIT:@索伦 这就是配置方法的样子。我已经设置了断点DetermineProviderCultureResult但访问网站时永远不会被点击。

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory, FinOsDbContext context)
    {
        loggerFactory.AddConsole(Configuration.GetSection("Logging"));
        loggerFactory.AddDebug();

        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
            app.UseDatabaseErrorPage();
            app.UseBrowserLink();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
        }

        app.UseStaticFiles();

        app.UseIdentity();

        // Add external authentication middleware below. To configure them please see http://go.microsoft.com/fwlink/?LinkID=532715

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

        //TODO: Clean up
        //var cultureInfo = new CultureInfo("en-US");
        //System.Threading.Thread.CurrentThread.CurrentCulture = cultureInfo;
        //System.Threading.Thread.CurrentThread.CurrentUICulture = cultureInfo;

        app.UseRequestLocalization();

        // UseCookieAuthentication..
        // UseJwtBearerAuthentication..

        //add userculture provider for authenticated user
        var requestOpt = new RequestLocalizationOptions();
        requestOpt.SupportedCultures = new List<CultureInfo>
        {
            new CultureInfo("en-US")
        };
        requestOpt.SupportedUICultures = new List<CultureInfo>
        {
            new CultureInfo("en-US")
        };
        requestOpt.RequestCultureProviders.Clear();
        requestOpt.RequestCultureProviders.Add(new SingleCultureProvider());

        app.UseRequestLocalization(requestOpt);

        FinOsDbContext.Initialize(context);
        FinOsDbContext.CreateTestData(context);
    }

    public class SingleCultureProvider : IRequestCultureProvider
    {
        public Task<ProviderCultureResult> DetermineProviderCultureResult(HttpContext httpContext)
        {
            return Task.Run(() => new ProviderCultureResult("en-US", "en-US"));
        }
    }

这就是为我解决的问题：

设置以下内容StartUp.Configure

var cultureInfo = new CultureInfo("en-US");
cultureInfo.NumberFormat.CurrencySymbol = "€";

CultureInfo.DefaultThreadCurrentCulture = cultureInfo;
CultureInfo.DefaultThreadCurrentUICulture = cultureInfo;
