使用 Automapper 3.1.1 我无法编译此地图:
Mapper.CreateMap<Domain.DomainObjects.Entities.Patient, PatientDto>()
.ForMember(x => x.Deleted, opt => opt.MapFrom(input => input.Deleted.HasValue ?
new DateTime(input.Deleted.Value.Ticks, DateTimeKind.Utc) : null ));
Error:
Type of conditional expression cannot be determined because there is no implicit conversion between '<null>' and 'DateTime'
Entity:
public class Patient : Entity
{
// more properties
public virtual DateTime? Deleted { get; set; }
}
感觉我错过了一些明显的东西,但无法弄清楚到底是什么。
注:Dto包含DateTime? Deleted
too
我还没有测试过,但你应该只需要显式转换null
to a DateTime?
. ((DateTime?)null
)
Mapper.CreateMap<Domain.DomainObjects.Entities.Patient, PatientDto>()
.ForMember(x => x.Deleted, opt => opt.MapFrom(input => input.Deleted == null ? (DateTime?)null : (
new DateTime(input.Deleted.Value.Ticks, DateTimeKind.Utc))));
