I\'m trying to implement the AutoMapper for a new module.

I have the MVC model at the web site, I\'m working on, and it looks like this:

public class         


        

Answer 1

Thank's to stuartd this are working now!

The thing that I didn't understand was, that I have to map bottom to top! All the sub-objects have to mapped first, so they would be recognized at the moment parent objects are mapped!

Now profile's looks like this:

public class Out: Profile
{
   protected override void Configure()
    {
        CreateMap<Step1, PersonalDetails>();
        CreateMap<Step2, Phones>();
        CreateMap<Step3, ElectonicCommunication>();

        CreateMap<Params, Parameters>();
        CreateMap<Params, RequestContent>()
            .ForMember(dest => dest.Id, opt => opt.MapFrom(src => src.RequestId))
            .ForAllMembers(opt => opt.Ignore());
        CreateMap<Steps, RequestContent>()
            .ForMember(dest => dest.PersonalDetails, opt => opt.MapFrom(src => src.Step1))
            .ForMember(dest => dest.Phones, opt => opt.MapFrom(src => src.Step2))
            .ForMember(dest => dest.ElectonicCommunication, opt => opt.MapFrom(src => src.Step3))
            .ForAllMembers(opt => opt.Ignore());

        CreateMap<MvcModel, Request>()
            .ForMember(dest => dest.Parameters, opt => opt.MapFrom(src => src.Params))
            .ForMember(dest => dest.RequestContent, opt => opt.MapFrom(src => src.Steps));
    }
}
