Convert list of id to Object using AutoMapper

I have objects :

class Group {
    public string GroupName ; 
    public List<Access> Details ; 
}

Class Access {
     public int Id;
     public string Name; 
}

Now I have a Dto like:

Class GroupDto
{
    string GroupName; 
    List<int> Details ; 
}

User can create/send GroupDto and converted to Group before saving.

how to define the MappingProfile for this ?

Like this:

Mapper.CreateMap<Group, GroupDto>()
                .ForMember(d => d.Details,
                    opt =>
                        opt.MapFrom(
                            s => s.Details.Select(x=>x.Id).ToList()))

In your mapping profile just use MapFrom method and let AutoMapper know how to get the data like below:

CreateMap<Group, GroupDto>()
    .ForMember(
        destination => destination.Details, 
        options => options.MapFrom(
            source => source.Details.Select(detail => detail.Id).ToList()
        )
    );

Side Note: please expose a property instead of field like you did in your sample. Also make sure that properties on GroupDto class are public too.
