C# 自动映射子类

我有一个方法定义了一些映射，如下所示：

/// <summary>
/// Mapping definitions for domain entities to database entities
/// </summary>
private static void DefineMappingDomainEntitiesToDatabase()
{
    // SellerListing 
    Mapper.CreateMap<SellerListing, Data.SellerListing>();

    // ListingShippingCost
    Mapper.CreateMap<ListingShippingCost, Data.ListingShippingCost>();
}

---

所以它告诉我，我没有ListingShippingCost的映射，即使我有ListingShippingCost的映射定义，正如您所见。显然，我需要为这个映射添加一些东西到我的SellerListing定义中，但我不确定是什么。

您应该定义映射ListingShippingCost属性的位置：

private static void DefineMappingDomainEntitiesToDatabase()
{
    // SellerListing 
    Mapper.CreateMap<SellerListing, Data.SellerListing>()
          .ForMember(x => x.ListingShippingCost, cfg => cfg.MapFrom(y => y.ListingShippingCostList));

    // ListingShippingCost
    Mapper.CreateMap<ListingShippingCost, Data.ListingShippingCost>();
}

private static void DefineMappingDomainEntitiesToDatabase（）
{
//卖方名单
Mapper.CreateMap（）
.ForMember（x=>x.ListingShippingCost，cfg=>cfg.MapFrom（y=>y.ListingShippingCostList））；
//上市运输成本
CreateMap（）；
}

SellerListing -> SellerListing (Destination member list)
MyApp.Entities.SellerListing -> MyApp.Data.SellerListing (Destination member list)

Unmapped properties:
ListingShippingCost

private static void DefineMappingDomainEntitiesToDatabase()
{
    // SellerListing 
    Mapper.CreateMap<SellerListing, Data.SellerListing>()
          .ForMember(x => x.ListingShippingCost, cfg => cfg.MapFrom(y => y.ListingShippingCostList));

    // ListingShippingCost
    Mapper.CreateMap<ListingShippingCost, Data.ListingShippingCost>();
}
