AutoMapper繼承錯誤

Question

我有以下的抽象類

public abstract class BaseClass 
{ 
    public int NumberProperty { get; set; } 
} 

public abstract class BaseClass_DTO 
{ 
    public int NumberProperty { get; set; } 
    public string NumberPropertyAsString { get; set; } 
} 

和下面的具體類

public class ConcreteA : BaseClass 
{ 
    public string StringProperty { get; set; } 
} 

public class ConcreteA_DTO : BaseClass_DTO 
{ 
    public string StringProperty { get; set; } 
} 

這是地圖

Mapper.Initialize(cfg => { 
    cfg.CreateMap<BaseClass, BaseClass_DTO>() 
     .ForMember(p => p.NumberPropertyAsString, opt => opt.MapFrom(x => x.NumberProperty.ToString())); 
    cfg.CreateMap<ConcreteA, ConcreteA_DTO>() 
     .IncludeBase<BaseClass, BaseClass_DTO>() 
     .ReverseMap(); 
}); 
Mapper.AssertConfigurationIsValid(); 

的代碼表示，配置無效，因爲

Unmapped members were found. Review the types and members below. 
Add a custom mapping expression, ignore, add a custom resolver, or modify the source/destination type 
============================================================================= 
ConcreteA_DTO -> ConcreteA (Source member list) 
Temporary.Test.ConcreteA_DTO -> Temporary.Test.ConcreteA (Source member list) 

Unmapped properties: 
NumberPropertyAsString 

由於ReverseMap()調用而發生錯誤。如何設置反向貼圖來忽略成員而不復制貼圖？

Answer 1

您需要使用

.ReverseMap() 
    .ForSourceMember(p => p.NumberPropertyAsString, opt => opt.Ignore()); 

看來，您的具體映射的配置，你應該配置在底座都和混凝土以及忽略反向映射的NumberPropertyAsString。

1.在基類映射中。

cfg.CreateMap<BaseClass, BaseClass_DTO>() 
    .ForMember(p => p.NumberPropertyAsString, opt => opt.MapFrom(x => x.NumberProperty.ToString())) 
    .ReverseMap() 
      .ForSourceMember(p => p.NumberPropertyAsString, opt => opt.Ignore()); 

2.在具體類的地圖。

cfg.CreateMap<ConcreteA, ConcreteA_DTO>() 
    .IncludeBase<BaseClass, BaseClass_DTO>() 
    .ReverseMap() 
     .ForSourceMember(p => p.NumberPropertyAsString, opt => opt.Ignore());
