C# Automapper Generic Mapping

Question

When playing around with AutoMapper I was wondering whether the following is possible to implement like this (haven't been able to set it up correctly).

Base Service:

public class BaseService<T, IEntityDTO> : IService<T, IEntityDTO> where T : class, IEntity
{
    private IUnitOfWork _unitOfWork;
    private IRepository<IEntity> _repository;
    private IMapper _mapper;

    public BaseService(IUnitOfWork unitOfWork, IMapper mapper)
    {
        _unitOfWork = unitOfWork;
        _repository = unitOfWork.Repository<IEntity>();
        _mapper = mapper;
    }

    public IList<IEntityDTO> GetAll()
    {
        return _mapper.Map<IList<IEntityDTO>>(_repository.GetAll().ToList());
    }
}

Concrete Service:

public class HotelService : BaseService<Hotels, HotelsDTO>, IHotelService
{

    private IUnitOfWork _unitOfWork;
    private IRepository<Hotels> _hotelsRepository;
    private IMapper _mapper;

    public HotelService(IUnitOfWork unitOfWork, IMapper mapper) : base(unitOfWork, mapper)
    {
        _unitOfWork = unitOfWork;
        _hotelsRepository = unitOfWork.Repository<Hotels>();
        _mapper = mapper;
    }
}

Current mappings:

public class AutoMapperProfileConfiguration : Profile
{
    protected override void Configure()
    {
        CreateMap<Hotels, HotelsDTO>().ReverseMap();
    }
}

I'm kindly clueless on how the mapping should be done. Anyone any advice or is this just not the way to go?

Managed to solve my problem with the following line of code which looks up the mapping of the passed entity to the basecontroller.

public List<TDTO> GetAll()
{
    var list = _repository.GetAll().ToList();
    return (List<TDTO>)_mapper.Map(list, list.GetType(), typeof(IList<TDTO>));
}
