인사말 전문가Automapper : 조건부 유형을 어떻게 매핑합니까?
그래서 기본적으로 TripFeeSchedule에 사용하기 위해 설정 한지도가 있는데, 여행 요금 일정은 IEnumerable 유형입니다. 나는 5 가지 정도의 ValueResolvers를 가질 필요가 없기 때문에 이것을 매핑하려고 노력 중이다.
내가 기본적으로 원하는 것은 단일 수수료 일정에서 OPtional 수수료 유형을 매핑하는 것입니다. 예를 들어 유형이 연체료 인 경우 가격 및 수수료를 검색하여 적절하게 표시하는 특정 유형을 매핑하려고합니다. 이러한 수수료가 항상 존재하지는 않기 때문에 가능한 한 간단하게하려고합니다.
Mapper.CreateMap<Trip, TripManagementViewModelCreateEdit>().ForMember(dto => dto.TripOverride, opt => opt.ResolveUsing<TripCompResolver>().FromMember(x => x.TripComp))
.ForMember(dto => dto.BusOverride, opt => opt.ResolveUsing<TripCompResolver>().FromMember(x => x.TransportComp)).ForMember(dto => dto.RentalSki, opt => opt.MapFrom<TripFeeSchedule>(x=> x.ScheduledFees.First()));
ScheduledFees이 나 사망, Refrenced하지 개체 말한다.
나는지도를 가지고 있으며
