.NET Core - Globalization and Localization - Class library

问题

Following this documentation on how to implement globalization and localization using .NET Core, my goal is to store all my resources in a single global resource file located in a different project, (class library).

Project 1 - Startup.cs

public class Startup
{
    public Startup(IHostingEnvironment env)
    {
        var builder = new ConfigurationBuilder()
            .SetBasePath(env.ContentRootPath)
            .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
            .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true);

        if (env.IsEnvironment("Development"))
        {
            builder.AddApplicationInsightsSettings(developerMode: true);
        }

        builder.AddEnvironmentVariables();
        Configuration = builder.Build();
    }

    public IConfigurationRoot Configuration { get; }

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddApplicationInsightsTelemetry(Configuration);

        services.AddLocalization(lo => lo.ResourcesPath = "/MYCLASSLIBRARY"); //External project ~ How?

        services.AddMvc(config =>
        {
            var policy = new AuthorizationPolicyBuilder()
                             .RequireAuthenticatedUser()
                             .Build();
            config.Filters.Add(new AuthorizeFilter(policy));
        });

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

                opts.DefaultRequestCulture = new RequestCulture(culture: "en-US", uiCulture: "en-US");
                opts.SupportedCultures = supportedCultures;
                opts.SupportedUICultures = supportedCultures;
            });
    }

    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
    {
        loggerFactory.AddConsole();

        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        app.UseRequestLocalization(app.ApplicationServices.GetService<IOptions<RequestLocalizationOptions>>().Value);

        app.UseMvc();

        app.UseDefaultFiles();

        app.UseStaticFiles();
    }
}

Project 2 - Class library

Project 1 - Controller

using MYCLASSLIBRARY; //External project

[Route("api/[controller]")]
public class HelloController : Controller
{
    private readonly IStringLocalizer<Test> _localizer; //External project class

    public OrganisationController(IStringLocalizer<Test> localizer)
    {
        _mapper = mapper;

        _localizer = localizer;
    }

    [HttpGet("GetResource")]
    public string GetResource()
    {
        return _localizer["Help"];
    }
}

How can I reference an external project when setting ResourcesPath?

services.AddLocalization(lo => lo.ResourcesPath = "/MYCLASSLIBRARY");

回答1:

Not sure you have already figured it out, just in case if you did not, here is the simple thing you could do in your current setup. Just replace the line below

services.AddLocalization(lo => lo.ResourcesPath = "/MYCLASSLIBRARY"); //External project ~ How? with

services.AddLocalization(); //Removing the root folder in the target assembly hence it will look for the file in the root of the assembly of your MYCLASSLIBRARY

Move your resource files under the folder "MYCLASSLIBRARY". Just make sure you don't remove the leading '/' when you define the ResourcesPath.

I hope it helps.
