mapping complex object with automapper

How can I convert IEnumerable<Category> to IEnumerable<CategoryViewModel> with this definition 

public class Category
    {
        public Guid Id { get; set; }
        public string Name { get; set; }
        public DateTime CreationTime { get; set; }

    }

public class CategoryViewModel
{
    public Guid  CategoryId { get; set; }
    public string Name { get; set; }
}

I have done like this 

public static IEnumerable<CategoryViewModel> ConvertToCategoryViewModelList(this IEnumerable<Category> category)
        {
            return Mapper.Map<IEnumerable<Category>, IEnumerable<CategoryViewModel>>(category);

but it doesn't map Id to CategoryId and also I don't want to have CreationTime in CategoryVeiwModel

Either property names should match, or you have to override the mapping for the Id. Also you have to explicitly Ignore the CreationTime:

AutoMapper.Mapper.CreateMap<Category, CategoryViewModel>()
.ForMember(x => x.CategoryId, src => src.MapFrom(y => y.Id))
.ForSourceMember(x => x.CreationTime, y => y.Ignore());

I think you can use inheritance and down cast (or is it up casting)

public class Category : CategoryViewModel
{
    public DateTime CreationTime { get; set; }
}

public class CategoryViewModel
{
    public Guid  CategoryId { get; set; }
    public string Name { get; set; }
}
