c# - Automapper继承——重用 map

Question

我正在尝试使用 automapper 为父对象创建单个映射并在其子对象中重复使用它。

对于子属性，我只想映射额外的字段。

这可能吗？我的代码看起来像这样

CreateCalculationMap(message);  ---- This does the BASE parent mappping.
    Mapper.CreateMap<QuoteMessage, CalculationGipMessage>()                     -- This is the child.
        .Include<QuoteMessage, CalculationBase>()                               -- Include the parent?
        .ForMember(a => a.OngoingCommission, b => b.MapFrom(c => c.OngoingASF)) - Child
        .ForMember(a => a.SpecialRate, b => b.MapFrom(c => c.BlahBlah)));       - Child

为什么它一直告诉我父属性没有映射？然而，我认为我将它们包含在 CreateCalculationMap(message);其中包含

Mapper.CreateMap<QuoteMessage, CalculationBase>() ()

Answer 1

仅供引用，我想通了

 public static IMappingExpression<A, T> ApplyBaseQuoteMapping<A, T>(this   IMappingExpression<A, T> iMappingExpression)
        where A : QuoteMessage
        where T : CalculationGipMessage
    {
        iMappingExpression
            .ForMember(a => a.LoginUserName, b=> b.MapFrom(c => c.LoginUserName))
            .ForMember(a => a.AssetTestExempt, b => b.Ignore())
            ;

        return iMappingExpression;
    }


Mapper.CreateMap<QuoteMessage, CalculationGipMessageChild>()
            .ApplyBaseQuoteMappingToOldCol()
             // do other mappings here
