更新1-13-10 我已經能夠找到一些成功使用下面的代碼進行映射。我基本上忽略了任何沒有映射的屬性，並在之後進行映射。我希望能夠以最好的方式迴應這個問題。另外，我不確定如何去執行這個映射的單元測試。我的印象是使用AutoMapper應該有助於減輕檢查每個屬性的乏味。Automapper自定義映射異常
這是我的新代碼：
Mapper.CreateMap<MoveEntity, MoveEntityDto>()
.ForMember(dest => dest.PrimaryOriginTransferee, opt => opt.Ignore())
.ForMember(dest => dest.PrimaryDestinationTransferee, opt => opt.Ignore())
.ForMember(dest => dest.Customer, opt => opt.Ignore())
.ForMember(dest => dest.DestinationAddress, opt => opt.Ignore())
.ForMember(dest => dest.OriginAddress, opt => opt.Ignore())
.ForMember(dest => dest.Order, opt => opt.Ignore())
.ForMember(dest => dest.Shipment, opt => opt.Ignore())
.ForMember(dest => dest.SourceSystemName, opt => opt.Ignore());
Mapper.CreateMap<ContactEntity, TransfereeEntityDto>();
Mapper.CreateMap<CustomerEntity, CustomerEntityDto>();
Mapper.CreateMap<AddressEntity, AddressEntityDto>();
Mapper.CreateMap<OrderEntity, OrderEntityDto>()
.ForMember(dest => dest.OrderForwarding, opt => opt.Ignore())
.ForMember(dest => dest.Forwarder, opt => opt.Ignore());
Mapper.CreateMap<ShipmentEntity, ShipmentEntityDto>()
.ForMember(dest => dest.Services, opt => opt.Ignore());
Mapper.CreateMap<ServiceEntity, ServiceEntityDto>()
.ForMember(dest => dest.ServiceTypeCode, opt => opt.Ignore()) //TODO: ServiceTypeCode not being mapped, should it?
.ForMember(dest => dest.SourceSystemName, opt => opt.MapFrom(src => Enum.GetName(typeof(SourceSystemName), src.SourceSystemName)));
Mapper.CreateMap<OrderForwardingEntity, OrderForwardingEntityDto>();
Mapper.AssertConfigurationIsValid();
MoveEntityDto moveEntityDto = Mapper.Map<MoveEntity, MoveEntityDto>(moveEntity);
moveEntityDto.PrimaryDestinationTransferee = Mapper.Map<ContactEntity, TransfereeEntityDto>(moveEntity.PrimaryDestinationTransferee);
moveEntityDto.PrimaryOriginTransferee = Mapper.Map<ContactEntity, TransfereeEntityDto>(moveEntity.PrimaryOriginTransferee);
moveEntityDto.Customer = Mapper.Map<CustomerEntity, CustomerEntityDto>(moveEntity.Customer);
moveEntityDto.DestinationAddress = Mapper.Map<AddressEntity, AddressEntityDto>(moveEntity.DestinationAddress);
moveEntityDto.OriginAddress = Mapper.Map<AddressEntity, AddressEntityDto>(moveEntity.OriginAddress);
moveEntityDto.Order = Mapper.Map<OrderEntity, OrderEntityDto>(moveEntity.Order);
moveEntityDto.Order.OrderForwarding = Mapper.Map<OrderForwardingEntity, OrderForwardingEntityDto>(moveEntity.Order.OrderForwarding);
//moveEntityDto.Order.Forwarder = Mapper.Map<ForwarderEntity, ForwarderEntityDto>(moveEntity.Order.Forwarder); //Apparently there is no forwarder entity for an Order
moveEntityDto.Shipment = Mapper.Map<ShipmentEntity, ShipmentEntityDto>(moveEntity.Shipment);
moveEntityDto.Shipment.Services = Mapper.Map<ServiceEntity[], ServiceEntityDto[]>(moveEntity.Shipment.ServiceEntities);
原貼：
我試圖使用AutoMapper首次以從經營業務對象的映射DTO。我跑，到我不知道如何解決的問題，包括以下情況除外：
AutoMapper.AutoMapperMappingException：試圖Graebel.SP.BO.MoveEntity映射到Graebel.SOA.Contracts.DataContracts.SP。 MoveEntity。類型 異常 'AutoMapper.AutoMapperMappingException' 被拋出
這裏是AutoMapper代碼，我運行：
public MoveEntityDto MapMoveEntityToMoveEntityDto(MoveEntity moveEntity)
{
Mapper.CreateMap<MoveEntity, MoveEntityDto>()
.ForMember(dest => dest.PrimaryOriginTransferee, opt => opt.MapFrom(src => src.PrimaryOriginTransferee))
.ForMember(dest => dest.PrimaryDestinationTransferee,opt => opt.MapFrom(src => src.PrimaryDestinationTransferee))
.ForMember(dest => dest.Customer, opt => opt.MapFrom(src => src.Customer))
.ForMember(dest => dest.DestinationAddress, opt => opt.MapFrom(src => src.DestinationAddress))
.ForMember(dest => dest.Order, opt => opt.MapFrom(src => src.Order))
.ForMember(dest => dest.OriginAddress, opt => opt.MapFrom(src => src.OriginAddress))
.ForMember(dest => dest.Shipment, opt => opt.MapFrom(src => src.Shipment))
.ForMember(dest => dest.SourceSystemName, opt => opt.Ignore());
Mapper.AssertConfigurationIsValid();
MoveEntityDto moveEntityDto = Mapper.Map<MoveEntity, MoveEntityDto>(moveEntity);
return moveEntityDto;
}
這裏是DTO（MoveEntityDto），我嘗試映射：
public class MoveEntityDto
{
public bool IsOrderDetailPageModified { get; set; }
public bool IsRoutingPageModified { get; set; }
public bool IsServicePageModified { get; set; }
public bool IsContentAndContainerPageModified { get; set; }
public string FamilyRange { get; set; }
public string Office { get; set; }
public string ActivityType { get; set; }
public string ActivitySubject { get; set; }
public string ActivityNote { get; set; }
public TransfereeEntity PrimaryOriginTransferee { get; set; }
public TransfereeEntity PrimaryDestinationTransferee { get; set; }
public CustomerEntity Customer { get; set; }
public AddressEntity OriginAddress { get; set; }
public AddressEntity DestinationAddress { get; set; }
public OrderEntity Order { get; set; }
public ShipmentEntity Shipment { get; set; }
public string PortalId { get; set; }
public string SourceSystemId { get; set; }
public EnterpriseEnums.SourceSystemName SourceSystemName { get; set; }
public MoveEntity()
{
PrimaryOriginTransferee = new TransfereeEntity();
PrimaryDestinationTransferee = new TransfereeEntity();
Customer = new CustomerEntity();
OriginAddress = new AddressEntity();
DestinationAddress = new AddressEntity();
Order = new OrderEntity();
Shipment = new ShipmentEntity();
}
public bool HasShipment()
{
if (Shipment.ExternalShipmentId > 0)
{
return true;
}
return false;
}
}
這裏是業務對象（MoveEntity），我想從
地圖每個類中的屬性幾乎完全按名稱匹配，但它們的類型不同。因此，我試圖使用「MapFrom」表達式執行自定義映射。但是，AutoMapper似乎無法讓我從一種對象類型指向另一種對象而沒有抱怨。
我也試過映射屬性到財產，沒有運氣。它看起來是這樣的：
.ForMember(dest => dest.PrimaryOriginTransferee.Email, opt => opt.MapFrom(src => src.PrimaryOriginTransferee.Email))
但是，試圖這樣的時候，我收到以下exeception：
必須解析到頂級成員。 參數名稱：lambdaExpression。
我一直在尋找可用於AutoMapper的文檔難以遵循。有人請指出我正確的方向，如何正確使用這個工具？
在此先感謝您的幫助！
