c# - 将 Asp.net Core 中的 CultureInfo 设置为具有 .作为 CurrencyDecimalSeparator 而不是 ,

Question

我要疯了。我只想将整个 Asp.net 核心应用程序中使用的文化设置为“en-US”。但似乎没有任何效果。我在哪里设置整个应用程序的文化？我对客户端浏览器文化不感兴趣。似乎唯一改变它的是改变 Windows 的语言设置。我只希望文化由应用程序本身决定，而不是由客户决定。

到目前为止我尝试了什么:

• 设置<system.web><globalization uiCulture="en" culture="en-US" /></system.web>在 web.config 中
• 设置System.Threading.Thread.CurrentThread.CurrentCulture = cultureInfo;和 CurrentUICulture在 Startup.Configure 中，甚至在 Controller 中。

• 使用 app.UseRequestLocalization(..如下图

      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)。

文化如何设置？

编辑: @索伦 这就是配置方法的样子。我在 DetermineProviderCultureResult 上设置了一个断点但它在访问该网站时从未被击中。

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"));
        }
    }

Answer 1

这就是为我解决的问题:

在 StartUp.Configure 中设置以下内容

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

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