我有以下抽象类及其实现:
public abstract class TransactionResult : AuditableEntity
{
public int Id { get; set; }
[Required, MaxLength(25)]
public string Status { get; set; }
[Required, MaxLength(50)]
public string ReferenceId { get; set; }
public string ResultMetaData { get; set; }
[Required, MaxLength(10)]
public string CardType { get; set; }
[Required, MaxLength(10)]
public string CardDescription { get; set; }
public int? CustomerSavedCardId { get; set; }
public CustomerSavedCard CustomerSavedCard { get; set; }
public int? PaymentPlanDetailId { get; set; }
public PaymentPlanDetail PaymentPlanDetail { get; set; }
public int? CustomerMembershipBillingId { get; set; }
public CustomerMembershipBilling CustomerMembershipBilling { get; set; }
public Guid? NotificationId { get; set; }
public Notification Notification { get; set; }
[Required, MaxLength(25)]
public string Source { get; set; }
public string CustomerKey { get; set; }
public Customer Customer { get; set; }
public int Amount { get; set; }
}
public class Approve : TransactionResult
{
}
public class Decline : TransactionResult
{
public string Reason { get; set; }
}
我在使用自动映射器时试图找出原因
profile.CreateMap<Entities.TransactionResult, TransactionsDto>()
.ForMember(dest => dest.CustomerName, opt => opt.MapFrom(src => src.Customer.FirstName + " " + src.Customer.LastName))
.ForMember(dest => dest.NotificationId, opt => opt.MapFrom(src => src.NotificationId))
.ForMember(dest => dest.Reason, opt => opt.MapFrom(src => src.GetType() == typeof(Entities.Decline) ? ((Entities.Decline)src).Reason : null))
向交易结果添加拒绝转换时出现错误。
<块引用>客户端投影包含对“System.RuntimeType”常量表达式的引用。这可能会导致内存泄漏;考虑将此常量分配给局部变量并在查询中使用该变量。有关详细信息,请参阅 https://go.microsoft.com/fwlink/?linkid=2103067。
答案 0 :(得分:1)
Automapper 支持继承。
删除属性 Reason
的行并为 Decline
创建特定配置文件,如下所示:
profile.CreateMap<Entities.Decline, TransactionsDto>()
.IncludeBase<Entities.TransactionResult, TransactionsDto>();
