如何向 ABP 模板添加新语言？答案

【问题标题】：How to add new language to ABP template?如何向 ABP 模板添加新语言？

【问题描述】：

我正在使用来自该站点https://aspnetboilerplate.com/Templates的免费样板文件（ASP.NET Core MVC 和 jQuery）

是否可以添加新的语言支持？

我已经添加了本地化的 .xml 文件，更新了数据库中的“abplanguages”表，但它不起作用。我正在更改语言，但文本仍然是英文。与“espanol-mexico”等样板已附带的预定义语言的情况相同，但当我选择“法语”时，页面被翻译。这很奇怪，因为在文档中说可以做到。 https://aspnetboilerplate.com/Pages/Documents/Localization#extending-localization-sources

不知道是免费模板限制吗？

【解决方案1】：

注入IApplicationLanguageManager接口并使用AddAsync()方法添加新语言。

private readonly IApplicationLanguageManager _applicationLanguageManager;


public LanguageAppService(
    IApplicationLanguageManager applicationLanguageManager,
    IApplicationLanguageTextManager applicationLanguageTextManager,
    IRepository<ApplicationLanguage> languageRepository)
{
    _applicationLanguageManager = applicationLanguageManager;
    _languageRepository = languageRepository;
    _applicationLanguageTextManager = applicationLanguageTextManager;
}


protected virtual async Task CreateLanguageAsync(ApplicationLanguageEditDto input)
{
    if (AbpSession.MultiTenancySide != MultiTenancySides.Host)
    {
        throw new UserFriendlyException(L("TenantsCannotCreateLanguage"));
    }

    var culture = CultureHelper.GetCultureInfoByChecking(input.Name);

    await _applicationLanguageManager.AddAsync(
        new ApplicationLanguage(
            AbpSession.TenantId,
            culture.Name,
            culture.DisplayName,
            input.Icon
        )
        {
            IsDisabled = !input.IsEnabled
        }
    );
}

public static class CultureHelper
{
    public static CultureInfo[] AllCultures = CultureInfo.GetCultures(CultureTypes.AllCultures);

    public static bool IsRtl => CultureInfo.CurrentUICulture.TextInfo.IsRightToLeft;

    public static bool UsingLunarCalendar = CultureInfo.CurrentUICulture.DateTimeFormat.Calendar.AlgorithmType == CalendarAlgorithmType.LunarCalendar;

    public static CultureInfo GetCultureInfoByChecking(string name)
    {
        try
        {
            return CultureInfo.GetCultureInfo(name);
        }
        catch (CultureNotFoundException)
        {
            return CultureInfo.CurrentCulture;
        }
    }
}


public class ApplicationLanguageEditDto
{
    public virtual int? Id { get; set; }

    [Required]
    [StringLength(ApplicationLanguage.MaxNameLength)]
    public virtual string Name { get; set; }

    [StringLength(ApplicationLanguage.MaxIconLength)]
    public virtual string Icon { get; set; }

    /// <summary>
    /// Mapped from Language.IsDisabled with using manual mapping in CustomDtoMapper.cs
    /// </summary>
    public bool IsEnabled { get; set; }
}

我想通了。就我而言，这是不正确的构建操作属性。在 VS 中右键单击本地化源文件：*.xml file -> Advanced -> Build action: Embedded resource。
