Following on from Eugene Gorbovoy's answer, if you're using profiles to configure your AutoMapper, you need to use a TypeConverter.

Create a new TypeConverter like this

    public class NumberConverter : ITypeConverter
    {
        public NumberBase Convert(DTO source, NumberBase destination, ResolutionContext context)
        {
            if (source.Id % 2 == 0)
            {
                return context.Mapper.Map(source);
            }
            else
            {
                return context.Mapper.Map(source);
            }
        }
    }

and replace the ConvertUsing line in his example with

  expression.CreateMap()
            .ConvertUsing(new NumberConverter());
