映射註冊時丟失類型映射配置或不支持的映射

Question

我一直在閱讀有關此問題的類似問題，但似乎無法理解解決方案。

我想映射我的實體到我的視圖模型，我注意到它失敗了一些我的實體。一個例子是以下幾點：

實體

public class Warehouse : EntityBase 
{ 
    [Index(IsUnique = true)] 
    [MaxLength(20)] 
    [Required] 
    public string Code { get; set; } 
    [Required] 
    public string Name { get; set; } 
    public string Description { get; set; } 
    public int AddressId { get; set; } 

    [ForeignKey("AddressId")] 
    public virtual Address Address { get; set; } 
    public virtual ICollection<Location> Locations { get; set; } 

    public Warehouse() 
    { 

    } 
} 

public abstract class EntityBase : IConcurrencyEnabled 
{ 
    [Key] 
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)] 
    public int Id { get; set; } 
    [Timestamp] 
    public byte[] RowVersion { get; set; } 
    public string CreatedBy { get; set; } 
    public DateTime DateCreated { get; set; } 
} 

視圖模型

public class WarehouseVM : VMBase 
{ 
    public string Code { get; set; } 
    [Required] 
    public string Name { get; set; } 
    public string Description { get; set; } 
    public int AddressId { get; set; } 

    public virtual AddressVM Address { get; set; } 
    public virtual ICollection<LocationVM> Locations { get; set; } 

    public WarehouseVM() 
    { 

    } 
} 

public abstract class VMBase 
{ 
    public int Id { get; set; } 
    public byte[] RowVersion { get; set; } 
    public string CreatedBy { get; set; } 
    public DateTime DateCreated { get; set; } 
} 

映射

public static TDestination Map<TSource, TDestination>(this TSource entity) 
    where TSource : class 
    where TDestination : class, new() 
{ 
    IMapper mapper = Core.Container.Get<IMapper>(); 

    return mapper.Map<TDestination>(entity); 
} 

用法

WMAS.Data.Entities.Warehouse warehouse = viewModel.Item.Map<WarehouseVM, WMAS.Data.Entities.Warehouse>();

我已經取得了一定註冊我的所有映射。在我的global.acx.cs中，我打電話給MapperConfig.RegisterMappings()。

public class MapperConfig 
{ 
    public static MapperConfiguration MapperCfg { get; private set; } 
    public static IMapper Mapper { get; private set; } 

    public static void RegisterMappings() 
    { 
     MapperCfg = new MapperConfiguration(cfg => 
     { 
      cfg.AllowNullCollections = true; 
      cfg.AllowNullDestinationValues = true; 
      cfg.CreateMap<Address, AddressVM>().ReverseMap(); 
      cfg.CreateMap<ApplicationUserDepartment, ApplicationUserDepartmentVM>().ReverseMap(); 
      cfg.CreateMap<BasicInfo, BasicInfoVM>().ReverseMap(); 
      cfg.CreateMap<CityMunicipality, CityMunicipalityVM>().ReverseMap(); 
      cfg.CreateMap<Company, CompanyVM>().ReverseMap(); 
      cfg.CreateMap<Country, CountryVM>().ReverseMap(); 
      cfg.CreateMap<Customer, CustomerVM>().ReverseMap(); 
      cfg.CreateMap<DeliverySlip, DeliverySlipVM>().ReverseMap(); 
      cfg.CreateMap<DeliverySlipItem, DeliverySlipItemVM>().ReverseMap(); 
      cfg.CreateMap<Department, DepartmentVM>().ReverseMap(); 
      cfg.CreateMap<Image, ImageVM>().ReverseMap(); 
      cfg.CreateMap<InventBatch, InventBatchVM>().ReverseMap(); 
      cfg.CreateMap<InventLedger, InventLedgerVM>().ReverseMap(); 
      cfg.CreateMap<Item, ItemVM>().ReverseMap(); 
      cfg.CreateMap<ItemCategory, ItemCategoryVM>().ReverseMap(); 
      cfg.CreateMap<Location, LocationVM>().ReverseMap(); 
      cfg.CreateMap<Module, ModuleVM>().ReverseMap(); 
      cfg.CreateMap<Province, ProvinceVM>().ReverseMap(); 
      cfg.CreateMap<PurchaseOrder, PurchaseOrderVM>().ReverseMap(); 
      cfg.CreateMap<PurchaseOrderItem, PurchaseOrderItemVM>().ReverseMap(); 
      cfg.CreateMap<Region, RegionVM>().ReverseMap(); 
      cfg.CreateMap<SalesInvoice, SalesInvoiceVM>().ReverseMap(); 
      cfg.CreateMap<SalesInvoiceItem, SalesInvoiceItemVM>().ReverseMap(); 
      cfg.CreateMap<SalesInvoicePayment, SalesInvoicePaymentVM>().ReverseMap(); 
      cfg.CreateMap<Submodule, SubmoduleVM>().ReverseMap(); 
      cfg.CreateMap<SysConfig, SysConfigVM>().ReverseMap(); 
     }); 

     Mapper = MapperCfg.CreateMapper(); 
    } 
} 

任何幫助表示讚賞。 TIA。

Answer 1

的關鍵是向開頭的消息的這一部分：

缺少類型映射配置或不支持的映射。

映射類型：WarehouseVM - >倉庫

您需要創建映射，以支持這一點：

cfg.CreateMap<WarehouseVM , Warehouse>(); 

Answer 2

的異常告訴你什麼是錯的：

缺少類型地圖配置或不支持的映射。

和丟失的映射是：

倉庫WMAS.Shared.Models.WarehouseVM - > WMAS.Data.Entities.Warehouse

檢查您MapperConfig我沒有看到來自WarehousVM映射到Warehouse。添加映射應該可以解決問題。
