c# - 在 ASP.NET Core 和 .NET Core 控制台项目中使用相同的 `.resx` 文件

Question

我已经根据以下内容在 ASP.NET Core 中实现了本地化:https://learn.microsoft.com/en-us/aspnet/core/fundamentals/localization

我有一个公共(public)库项目 ( MyProject.Common )，我在其中保存资源文件(因为它被多个 ASP.NET Core 应用程序使用)。

所以我有一个 .resx MyProject.Common\Resources\Localization\SharedResources.sv.resx 下的文件:

<?xml version="1.0" encoding="utf-8"?>
<root>
  <xsd:schema id="root" xmlns="" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">

              <xsd:attribute ref="xml:space" />
            </xsd:complexType>
          </xsd:element>
          <xsd:element name="resheader">
            <xsd:complexType>
              <xsd:sequence>

              </xsd:sequence>
              <xsd:attribute name="name" type="xsd:string" use="required" />
            </xsd:complexType>

        </xsd:choice>
      </xsd:complexType>
    </xsd:element>
  </xsd:schema>
  <resheader name="resmimetype">
    <value>text/microsoft-resx</value>

  <resheader name="version">

  <resheader name="reader">

  </resheader>
  <data name="English string" xml:space="preserve">
    <value>Swedish string</value>
  </data>
</root>

我有一个空的 .cs MyProject.Common\Localization\SharedResources.cs 下的文件看起来像这样:

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
    {
    }
}

我有一个类叫做 Localizer我用来获取翻译后的字符串:

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];
            }
        }
    }
}

它是这样使用的(如果请求的文化是瑞典语，将返回瑞典语翻译):

_localizer["English string"];

在Startup.cs对于每个 ASP.NET Core 项目，我都像这样配置本地化:

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？如果我尝试使用我的自定义 Localizer通过依赖注入(inject)，我得到:'Unable to resolve service for type 'Microsoft.AspNetCore.Hosting.IHostingEnvironment' while attempting to activate 'Microsoft.Extensions.Localization.ResourceManagerStringLocalizerFactory .所以这是因为 Microsoft.Extensions.Localization依赖于 ASP.NET Core，它在我的控制台项目中不存在。

我怎样才能使用相同的 .resx我的控制台项目中的文件？

Answer 1

我知道我来晚了一点，但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，所以你需要手动处理文化查找/存储/任何东西，但是一旦你知道文化就可以像这样访问你的翻译(不需要依赖注入(inject)!):

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标记的好方法，但这应该足以翻译公共(public)资源文件。

注意:这适用于 .Net Core 2.0，尚未在其他版本中测试。
