Automapper Mapping for Localization Resolver in a Multi-Language Website - asp.net-mvc

Question

I found a way to use Automapper for Language mapping based on the active Culture.
The question is if it's possible to build a generic Resolver to map all the models that use the Resolver.
In this Case, the models to map have always the same properties, Id and Name (including the language properties Name_PT, Name_FR and Name_EN):
// MODELS
public class MakeDto
{
// Primary properties
public int Id { get; set; }
public string Name { get; set; }
public string Name_PT { get; set; }
public string Name_FR { get; set; }
public string Name_EN { get; set; }
}
public class MakeViewModel
{
// Primary properties
public int Id { get; set; }
public string Name { get; set; }
}
public class ModelDto
{
// Primary properties
public int Id { get; set; }
public string Name { get; set; }
public string Name_PT { get; set; }
public string Name_FR { get; set; }
public string Name_EN { get; set; }
}
public class ModelViewModel
{
// Primary properties
public int Id { get; set; }
public string Name { get; set; }
}
public class FuelDto
{
// Primary properties
public int Id { get; set; }
public string Name { get; set; }
public string Name_PT { get; set; }
public string Name_FR { get; set; }
public string Name_EN { get; set; }
}
public class FuelViewModel
{
// Primary properties
public int Id { get; set; }
public string Name { get; set; }
}
// AUTOMAPPER PROFILE
public class DtoToViewModelMappingProfile : Profile
{
public override string ProfileName
{
get { return "DtoToViewModelMappings"; }
}
protected override void Configure()
{
CreateMaps();
}
private static void CreateMaps()
{
Mapper.CreateMap<ModelDto, ModelViewModel>();
Mapper.CreateMap<MakeDto, MakeViewModel>()
.ForMember(dest => dest.Name, opt => opt.ResolveUsing<CultureResolver>());
Mapper.CreateMap<FuelDto, FuelViewModel>();
}
public class CultureResolver : ValueResolver<MakeDto, string>
{
protected override string ResolveCore(MakeDto makeDto)
{
switch(Thread.CurrentThread.CurrentUICulture.TwoLetterISOLanguageName.ToUpperInvariant())
{
case "FR":
return makeDto.Name_FR;
case "EN":
return makeDto.Name_EN;
}
return makeDto.Name_PT;
}
}
}
Thanks.

You can extract an interface like below:
public interface ILocalizable
{
string Name { get; set; }
string Name_PT { get; set; }
string Name_FR { get; set; }
string Name_EN { get; set; }
}
public class FuelDto : ILocalizable
{
// Primary properties
public int Id { get; set; }
public string Name { get; set; }
public string Name_PT { get; set; }
public string Name_FR { get; set; }
public string Name_EN { get; set; }
}
Then tune your resolver like below:
public class CultureResolver : ValueResolver<ILocalizable, string>
{
protected override string ResolveCore(ILocalizable dto)
{
switch(Thread.CurrentThread.CurrentUICulture.TwoLetterISOLanguageName.ToUpperInvariant())
{
case "FR":
return dto.Name_FR;
case "EN":
return dto.Name_EN;
}
return dto.Name_PT;
}
}
