自動映射器和基類

Question

首先讓我說我是自動映射器的新手。 我有一個基類，其類繼承如下：

public abstract class Base
{
    [Required]
    public Guid CreatedBy { get; set; }
    [Required]
    public DateTime DateCreated { get; set; }
    [Required]
    public DateTimeOffset DateCreatedOffset { get; set; }
    public Guid? UpdatedBy { get; set; }
    public DateTime? DateUpdated { get; set; }
    public DateTimeOffset? DateUpdatedOffset { get; set; }
    [Required]
    public bool Deleted { get; set; }
}

public class Customer : Base
{
    [Key]
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public Guid CustomerId { get; set; }

    [Required]
    public Guid CompanyId { get; set; }
    public virtual Company Company { get; set; }

    [Required]
    public TypeCustomer CustomerType { get; set; }

    [Display(Name = "Customer Name")]
    public string CustomerName { get; set; }

    [StringLength(20)]
    [Display(Name = "First Name")]
    public string FirstName { get; set; }

    [StringLength(20)]
    [Display(Name = "Last Name")]
    public string LastName { get; set; }

    [DataType(DataType.EmailAddress)]
    public string PrimaryEmail { get; set; }

    public virtual ICollection<Address> Addresses { get; set; }
    public virtual ICollection<PhoneNumber> PhoneNumbers { get; set; }
}

要映射的類如下：

public class CustomerObject
{
    public Guid CustomerId { get; set; }
    public Guid CompanyId { get; set; }
    public Guid CreatedBy { get; set; }
    public DateTime DateCreated { get; set; }
    public DateTimeOffset DateCreatedOffset { get; set; }
    public Guid UpdatedBy { get; set; }
    public DateTime? DateUpdated { get; set; }
    public DateTimeOffset? DateUpdatedOffset { get; set; }
    public TypeCustomer CustomerType { get; set; }
    public string CustomerName { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    [DataType(DataType.EmailAddress)]
    public string PrimaryEmail { get; set; }

    public virtual ICollection<AddressObject> Addresses { get; set; }
    public virtual ICollection<PhoneNumberObject> PhoneNumbers { get; set; }
}

映射類的代碼：

    Customer customer = GetCustomerById(customerObject.CustomerId);
    Mapper.CreateMap<CustomerObject, Customer>();
    customer = Mapper.Map<CustomerObject, Customer>(customerObject);
    customer.UpdatedBy = userId;
    customer.DateUpdated = DateTime.UtcNow;
    customer.DateUpdatedOffset = DateTimeOffset.UtcNow;

嘗試將客戶類的實例映射到客戶對象時，我丟失了基類的所有屬性。 有人碰到這個嗎？

首先，您使用的是哪個版本的AutpMapper？ 我假設您正在使用nuget軟件包的最新版本4.0.4

如果是，那么此功能已經存在於automapper中，這是一個小提琴，它表明
