在ASP.NET Core和.NET Core控制台项目中使用相同的`.resx`文件 [英] Use same `.resx` file in ASP.NET Core and .NET Core console project
问题描述
我已根据此方法在ASP.NET Core中实现了本地化： https://docs.microsoft.com/zh-cn/aspnet/core/fundamentals/localization
I've implemented localization in ASP.NET Core according to this: https://docs.microsoft.com/en-us/aspnet/core/fundamentals/localization
我有一个公共图书馆项目（ MyProject.Common ）保存资源文件（因为它被多个ASP.NET Core应用程序使用）。
I have a common library project (MyProject.Common) where I keep the resource file (since it is used by multiple ASP.NET Core applications).
所以我在 MyProject.Common\Resources\Localization\SharedResources.sv.resx 下有一个 .resx 文件：
So I have a .resx file under MyProject.Common\Resources\Localization\SharedResources.sv.resx:
<?xml version="1.0" encoding="utf-8"?>

</resheader>
<data name="English string" xml:space="preserve">
<value>Swedish string</value>
</data>
</root>
我有一个空的 .cs 文件在 MyProject.Common\Localization\SharedResources.cs 下，如下所示：
And I have an empty .cs file under MyProject.Common\Localization\SharedResources.cs that looks like this:
namespace MyProject.Common.Localization
{
/// <summary>
/// This is just a placeholder so that we can have all our resources in the same .resx file
/// </summary>
public class SharedResources
{
}
}
我有一个名为 Localizer 的类，可用于获取翻译后的字符串：
I have a class called Localizer that I use to get translated strings:
using System;
using Microsoft.Extensions.Localization;
namespace MyProject.Common.Localization
{
public class Localizer
{
private readonly IStringLocalizer _localizer;
public Localizer(IStringLocalizer<SharedResources> localizer)
{
_localizer = localizer;
}
public virtual LocalizedString this[string name]
{
get
{
if (name == null)
{
throw new ArgumentNullException(nameof(name));
}
return _localizer[name];
}
}
public virtual LocalizedString this[string name, params object[] arguments]
{
get
{
if (name == null)
{
throw new ArgumentNullException(nameof(name));
}
return _localizer[name, arguments];
}
}
}
}
就像这样使用（如果请求的语言是瑞典语，将返回瑞典语翻译）：
And it is used liked this (will return swedish translation if culture of the request is swedish):
_localizer["English string"];
在 Startup.cs 中，每个ASP.NET Core项目我按如下方式配置本地化：
In Startup.cs for each of the ASP.NET Core projects I configure localization like this:
services
// Add the localization services to the services container
.AddLocalization(options => options.ResourcesPath = "Resources")
// Configure supported cultures and localization options
.Configure<RequestLocalizationOptions>(options =>
{
var supportedCultures = new[]
{
new CultureInfo("en"),
new CultureInfo("sv")
};
// State what the default culture for your application is. This will be used if no specific culture
// can be determined for a given request.
options.DefaultRequestCulture = new RequestCulture(culture: "en", uiCulture: "en");
// You must explicitly state which cultures your application supports.
// These are the cultures the app supports for formatting numbers, dates, etc.
options.SupportedCultures = supportedCultures;
// These are the cultures the app supports for UI strings, i.e. we have localized resources for.
options.SupportedUICultures = supportedCultures;
});
我想弄清楚如何在（.NET Core）控制台应用程序中重用它吗？如果尝试通过依赖项注入使用自定义的 Localizer ，则会得到：'无法解析类型为'Microsoft.AspNetCore.Hosting.IHostingEnvironment的服务'尝试激活 Microsoft.Extensions.Localization.ResourceManagerStringLocalizerFactory 时。因此，这是因为 Microsoft.Extensions.Localization 依赖于ASP.NET Core，这在我的控制台项目中不存在。
I'm trying to figure out how to reuse this in a (.NET Core) console application? If I try to use my custom Localizer via dependency injection, I get: 'Unable to resolve service for type 'Microsoft.AspNetCore.Hosting.IHostingEnvironment' while attempting to activate 'Microsoft.Extensions.Localization.ResourceManagerStringLocalizerFactory. So this is because Microsoft.Extensions.Localization is dependent on ASP.NET Core, which doesn't exist in my console project.
如何在控制台项目中使用相同的 .resx 文件？
How can I use the same .resx file in my console project?
推荐答案
我知道我在这里参加聚会有点晚了，但是您应该可以直接访问您的翻译。当然，在控制台应用程序中没有请求本地化这样的概念，因此您将需要手动处理区域性查找/存储/任何操作，但是一旦您了解区域性，就可以像这样访问您的翻译（无需依赖注入） ！）：
I know I'm a bit late to the party here but you should be able to access your translations directly. Of course in a console app there is no such concept as request localization, so you'll need to manually handle culture lookup/storage/whatever, but once you know the culture it is possible to access your translations like this (no dependency injection required!):
var german = new System.Globalization.CultureInfo("de-DE");
var english = new System.Globalization.CultureInfo("en-AU");
// result "Guten tag"
var greeting1 = Shared.Resources.Lang.ResourceManager.GetString("GREETING", german);
// result "Gidday mate"
var greeting2 = Shared.Resources.Lang.ResourceManager.GetString("GREETING", english);
您可能会想出一种处理语言代码和资源令牌的好方法，但这应该足够了来翻译公共资源文件。
You can probably figure out a nice way to handle language codes and resource tokens, but this should be enough to do your translations common resource files.
注意：这在.Net Core 2.0中有效，未在其他版本中进行过测试。
NOTE: this works in .Net Core 2.0, haven't tested in other versions.
