我正在对一种方法进行单元测试,该方法使用自动映射器将我的域中的类映射到 linq to sql 类。粗略地说,类和映射如下(SupplierEligibilityAllocated 是 L2S 自动生成的类)。
public class SupplierEligibilityTransactionByQuantity
{
public decimal Eligibility { get; private set; }
public decimal CoreValue { get; private set; }
public int? TransactionId { get; private set; }
public SupplierTransactionStatus Status { get; private set; }
public int? DebitId { get; set; }
public int ManifestId { get; private set; }
}
public partial class SupplierEligibilityAllocated
{
private int _SupplierEligibilityCreditId;
private int _ManifestId;
private System.Nullable<int> _QuantityApplied;
private System.Nullable<decimal> _AmountApplied;
private System.Nullable<decimal> _CoresReservedByAmount;
private System.DateTime _InsertDate;
private EntityRef<Manifest> _Manifest;
private EntityRef<SupplierEligibilityCredit> _SupplierEligibilityCredit;
}
private static void Map_SupplierEligibilityTransactionByQuantity_To_SupplierEligibilityAllocated()
{
Mapper.CreateMap<EligibilityTransactionByQuantity, SupplierEligibilityAllocated>()
.ForMember(dest => dest.SupplierEligibilityCreditId, opt => opt.MapFrom(src => src.TransactionId))
.ForMember(dest => dest.ManifestId, opt => opt.MapFrom(src => src.ManifestId))
.ForMember(dest => dest.QuantityApplied, opt => opt.MapFrom(src => Convert.ToInt32(src.Eligibility)))
.ForMember(dest => dest.AmountApplied, opt => opt.Ignore())
.ForMember(dest => dest.CoresReservedByAmount, opt => opt.Ignore())
.ForMember(dest => dest.InsertDate, opt => opt.MapFrom(src => DateTime.UtcNow))
.ForMember(dest => dest.Manifest, opt => opt.Ignore())
.ForMember(dest => dest.SupplierEligibilityCredit, opt => opt.Ignore());
}
但是,当该方法执行映射时,它会抛出以下异常。
Trying to map SupplierEligibilityTransactionByQuantity to SupplierEligibilityAllocated.
Missing type map configuration or unsupported mapping.
Exception of type 'AutoMapper.AutoMapperMappingException' was thrown.

at AutoMapper.Mapper.Map[TSource,TDestination](TSource source)
我在测试之前验证了我正在创建映射,并且我毫无问题地调用了 Mapper.AssertConfigurationIsValid()
。我也手动进行了映射,没有任何问题。有人知道是什么原因造成的吗?
最佳答案
看来您在调用 Mapper.CreateMap
时指定了错误的类型
尝试做如下的事情:
Mapper.CreateMap<SupplierEligibilityTransactionByQuantity, SupplierEligibilityAllocated>()
关于c# - 使用 AutoMapper 获取异常,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/1942691/
