asp.net-core - Asp.net Core MVC 视图本地化 IsResourceNotFound = true 在默认语言环境之外

Question

我想在我的 ASP.NET CORE MVC 应用程序中添加本地化，​​并将 ar-SA 作为默认本地化。我按照下面的链接配置了所有东西。我的默认语言环境是 ar-SA 并且运行良好。但是当我将语言环境更改为 en-US IsResourceNotFound 始终为真并且找不到资源

启动.cs

   services.AddLocalization(options => options.ResourcesPath = "Resources");
        services.AddMvc()
            .AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix)
            .AddDataAnnotationsLocalization();
  var supportedCultures = new[]
        {
           new CultureInfo("ar-SA"),
           new CultureInfo("en-US"),
        };
        app.UseRequestLocalization(new RequestLocalizationOptions
        {
            DefaultRequestCulture = new RequestCulture("ar-SA"),
            SupportedCultures = supportedCultures,
            SupportedUICultures = supportedCultures
        });

我也尝试过 .AddViewLocalization(LanguageViewLocationExpanderFormat.SubFolder) 和相同的结果
