鉴于上述类和表结构，我可以，如果可以，我如何正确地告诉EntityFramework这些类是如何存储在数据库中的？我正在从CastleActiveRecord（位于NHibernate顶部）迁移，它使用了一个嵌套属性，带有选项列前缀。另外，我不知道这个构造的正确名称是什么（如果有），我知道TPT、TPC和TPH，但我还没有找到它的名称。

对于实体框架，您所谓的“嵌套数据库类”的终端技术是

在EF术语中，它不是一个“实体”（它有自己的标识，在大多数情况下有自己的数据库表），因此名称

AddressEntity

不是最好的，最好是

AddressType

将类本身标记为“ComplexType”，而不是包含类中的单个属性（例如，

FacilityLocation

）：

不幸的是，EF并没有提供像我所知道的示例中的

columnprofix

映射那样简单的前缀重命名。您必须一个接一个地映射属性，并且必须使用Fluent API进行映射，使用数据注释无法实现这一点：

（在C#中）：

modelBuilder.Entity（）
.Property（a=>a.FacilityLocation.Street）
.HasColumnName（“FLStreet”）；
modelBuilder.Entity（）
.Property（a=>a.FacilityLocation.Suite）
.HasColumnName（“FLSuite”）；
//等等。
