Automapper - 地圖抽象到抽象

Question

源類：

public abstract class ApplicationDriverEquipmentFormAbstractVM 
{ 
    [StringLength(256)] 
    public string Make { get; set; } 
    [StringLength(256)] 
    public string Model { get; set; } 
    [StringLength(256)] 
    public string Year { get; set; } 
    [StringLength(256)] 
    public string PlateNumber { get; set; } 
    [StringLength(256)] 
    public string CurrentMileage { get; set; } 
} 

public class ApplicationDriverEquipmentTractorFormVM : ApplicationDriverEquipmentFormAbstractVM 
{ 
    [StringLength(256)] 
    public string VINNumber { get; set; } 
} 

public class ApplicationDriverEquipmentTrailerFormVM : ApplicationDriverEquipmentFormAbstractVM 
{ 
    [StringLength(256)] 
    public string Length { get; set; } 
} 

public class ApplicationDriverEquipmentStraightTruckFormVM : ApplicationDriverEquipmentFormAbstractVM 
{ 
    [StringLength(256)] 
    public string VINNumber { get; set; } 
    [StringLength(256)] 
    public string Length { get; set; } 
} 

public class ApplicationDriverEquipmentCargoVanFormVM : ApplicationDriverEquipmentFormAbstractVM 
{ 
    [StringLength(256)] 
    public string VINNumber { get; set; } 
    [StringLength(256)] 
    public string Length { get; set; } 
} 


public class ApplicationDriverFormVM 
{ 
    public ApplicationDriverEquipmentTractorFormVM EquipmentTractor { get; set; } 
    public ApplicationDriverEquipmentTrailerFormVM EquipmentTrailer { get; set; } 
    public ApplicationDriverEquipmentStraightTruckFormVM EquipmentStraightTruck { get; set; } 
    public ApplicationDriverEquipmentCargoVanFormVM EquipmentCargoVan { get; set; } 

} 

那麼我想它映射到目標類的設備屬性，它描述的方式如下：

public class ApplicationDriverDomain 
{ 
    public List<ApplicationDriverEquipmentAbstractDomain> Equipments { get; set; } 
} 

public abstract class ApplicationDriverEquipmentAbstractDomain 
{ 
    public int Id { get; set; } 
    public string Make { get; set; } 
    public string Model { get; set; } 
    public string Year { get; set; } 
    public string PlateNumber { get; set; } 
    public string CurrentMileage { get; set; } 
    public string Type { get; protected set; } 
} 

public class ApplicationDriverEquipmentTractorDomain : ApplicationDriverEquipmentAbstractDomain 
{ 
    public ApplicationDriverEquipmentTractorDomain() 
    { 
     Type = ApplicationDriverEquipmentTypeStaticStringsDomain.Tractor; 
    } 
    public string VINNumber { get; set; } 
} 

public class ApplicationDriverEquipmentTrailerDomain : ApplicationDriverEquipmentAbstractDomain 
{ 
    public ApplicationDriverEquipmentTrailerDomain() 
    { 
     Type = ApplicationDriverEquipmentTypeStaticStringsDomain.Trailer; 
    } 

    public string Length { get; set; } 
} 

public class ApplicationDriverEquipmentStraightTruckDomain : ApplicationDriverEquipmentAbstractDomain 
{ 
    public ApplicationDriverEquipmentStraightTruckDomain() 
    { 
     Type = ApplicationDriverEquipmentTypeStaticStringsDomain.StraightTruck; 
    } 

    public string VINNumber { get; set; } 
    public string Length { get; set; } 
} 

public class ApplicationDriverEquipmentCargoVanDomain : ApplicationDriverEquipmentAbstractDomain 
{ 
    public ApplicationDriverEquipmentCargoVanDomain() 
    { 
     Type = ApplicationDriverEquipmentTypeStaticStringsDomain.CargoVan; 
    } 

    public string VINNumber { get; set; } 
    public string Length { get; set; } 
} 

我已經寫了遵循自動映射器規則：

 CreateMap<ViewModels.ApplicationDriverEquipmentFormAbstractVM, ApplicationDriverEquipmentAbstractDomain>(); 

     CreateMap<ViewModels.ApplicationDriverEquipmentTractorFormVM, ApplicationDriverEquipmentTractorDomain>(); 
     CreateMap<ViewModels.ApplicationDriverEquipmentTrailerFormVM, ApplicationDriverEquipmentTrailerDomain>(); 
     CreateMap<ViewModels.ApplicationDriverEquipmentStraightTruckFormVM, ApplicationDriverEquipmentStraightTruckDomain>(); 
     CreateMap<ViewModels.ApplicationDriverEquipmentCargoVanFormVM, ApplicationDriverEquipmentCargoVanDomain>(); 

     CreateMap<ViewModels.ApplicationDriverFormVM, ApplicationDriverDomain>() 
      .ForMember(dest => dest.Equipments, opt => opt.MapFrom(src => new List<ViewModels.ApplicationDriverEquipmentFormAbstractVM>() { src.EquipmentCargoVan, src.EquipmentStraightTruck, src.EquipmentTractor, src.EquipmentTrailer })); 

但它不起作用。爲什麼？

Answer 1

我找到了解決方案。需要聲明的映射繼承：

 CreateMap<ViewModels.ApplicationDriverEquipmentFormAbstractVM, ApplicationDriverEquipmentAbstractDomain>() 
      .Include<ViewModels.ApplicationDriverEquipmentTractorFormVM, ApplicationDriverEquipmentTractorDomain>() 
      .Include<ViewModels.ApplicationDriverEquipmentTrailerFormVM, ApplicationDriverEquipmentTrailerDomain>() 
      .Include<ViewModels.ApplicationDriverEquipmentStraightTruckFormVM, ApplicationDriverEquipmentStraightTruckDomain>() 
      .Include<ViewModels.ApplicationDriverEquipmentCargoVanFormVM, ApplicationDriverEquipmentCargoVanDomain>() 
      ;
