c# - ASP.NET 核心 3.1 : Shared Localization not working for version 3. 1

Question

我可能没有在 startup.cs 中进行正确的配置文件。我创建了一个演示应用程序以使其正常工作，但是在尝试了各种操作后它不起作用。演示存储库可在以下链接中获得

https://github.com/gurpreet42/MyAppV3

startup.cs 文件的配置是

public void ConfigureServices(IServiceCollection services)
{
   services.AddSingleton<LocService>();
   services.AddLocalization(options => options.ResourcesPath = "Resources");

   services.Configure<RequestLocalizationOptions>(options =>
            {
                var supportedCultures = new List<CultureInfo>
                                            {
                                                new CultureInfo("en-US"),
                                                new CultureInfo("nl")
                                            };

                options.DefaultRequestCulture = new RequestCulture("en-US");
                options.SupportedCultures = supportedCultures;
                options.SupportedUICultures = supportedCultures;
            });

   services.AddMvc()
           .AddViewLocalization()
           .AddDataAnnotationsLocalization(options =>
                {
                   options.DataAnnotationLocalizerProvider = (type, factory) =>
                   {
                       var assemblyName = new AssemblyName(typeof(SharedResource).GetTypeInfo().Assembly.FullName);
                       return factory.Create("SharedResource", assemblyName.Name);
                   };
               }).SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
}

public void Configure(IApplicationBuilder app,
                        IHostingEnvironment env,
                        ILoggerFactory loggerFactory)
{
    // Localisation
    var locOptions = app.ApplicationServices.GetService<IOptions<RequestLocalizationOptions>>();
    app.UseRequestLocalization(locOptions.Value);

    app.UseHttpsRedirection();
    app.UseStaticFiles();
    app.UseAuthentication();
    app.UseSession();

    app.UseSession();
    app.UseCookiePolicy();
}

LocService中的代码类(class)是

public class LocService
{
    private readonly IStringLocalizer _localizer;

    public LocService(IStringLocalizerFactory factory)
    {
        var type = typeof(SharedResource);
        var assemblyName = new AssemblyName(type.GetTypeInfo().Assembly.FullName);
        _localizer = factory.Create("SharedResource", assemblyName.Name);
    }

    public LocalizedString GetLocalizedHtmlString(string key)
    {
        var value= _localizer[key];
        return value;
    }
}

现在在我们的 Controller 上，我们可以访问本地化的字符串

localizerService.GetLocalizedHtmlString("my_string")

在“资源”文件夹下，我们有以下文件

SharedResource.cs
SharedResource.en-US.resx
SharedResource.nl.resx

请建议配置错误的地方还是我需要添加一些额外的包？

Answer 1

原来在asp.net core 3.1中，需要放置SharedResource.cs出Resources文件夹(见此 github issue)

如果类SharedResource.cs和 SharedResource.*.resx在同一文件夹中，命名空间将在编译的 dll 中出错 xxx.lang.dll .

所以，删除原来的SharedResource.cs直接在项目下新建一个:

namespace MyAppV3
{
    public class SharedResource
    {
    }
}

并将资源文件读到 Resources文件夹。
