mapping - Automapper 复杂映射

Question

我如何映射以下内容:

public abstract class PersonBase
{
   public Address Address { get; set; }         
}

public class Address
{
  public string AddressHome { get; set; }
  public int PostalNumber { get; set; }
}

public class PersonEditVM : PersonBase
{ 
   public int PersonId { get; set; }
}

public PersonEntity
{
  public int PersonId { get; set; }
  public string AddressHome { get; set; }
  public int PostalNumber { get; set; }
}

我要 map PersonEntity至 PersonEditVM .

编辑: 一杯咖啡后解决了，但如果它是一个更清洁的解决方案会很好吗？。

Mapper.CreateMap<PersonEntity, PersonEditVM >()                
                .ForMember(d=>d.Address, s=>s.MapFrom(p=> new Address{
                    AddressHome = p.AddressHome,
                    PostalNumber = p.PostalNumber
                    }));

这是一种方法，它会 split 您的 Adress (顺便说一下，这是正确拼写的 Address)映射到另一个 CreateMap称呼:

Mapper.CreateMap<PersonEntity, PersonEditVM>()
    .ForMember(dest => dest.Adress, opt => opt.MapFrom(src => src));

Mapper.CreateMap<PersonEntity, Adress>()
    .ForMember(dest => dest.AdressHome, opt => opt.MapFrom(src => src.AdressHome))
    .ForMember(dest => dest.PostalNumber, opt => opt.MapFrom(src => src.PostalNumber));
