我有相当复杂的 EF 映射现实场景,它似乎只有在我打破封装时才有效。也许有人会弄清楚如何正确地做到这一点,或者我们会接受这是一个错误。

我有 2 个项目,我们称它们DomainPersistance. 包含 POCO 类,并通过属性Domain公开其内部。PersistanceInternalsVisibleTo

在内部Domain(目的是坚持SomeProduct):

pubic class Company { ... }
pubic class InsuranceCompany : Company { ... }

pubic class Product<TCompany> where TCompany : Company
{
    ...
    public CustomValueType SomeProp { ... 
      // get/set from/into SomePropInternal 
    }
    internal string SomePropInternal { get;set; } 
    // exposed as internal to be accessible from EF mappings
}

public class SomeProduct : Product<InsuranceCompany> 
{
    ...
    public AnotherCustomValueType AnotherSomeProp { ... 
      // get/set from/into AnotherSomePropInternal 
    }
    internal string AnotherSomePropInternal { get;set; } 
    // exposed as internal to be accessible from EF mappings
}

我需要以一张SomeProduct包含所有字段的表格结束。所以,在Persistance我们有:

里面Persistance

所有的基本配置类型Products

public class ProductEntityTypeConfiguration<TProduct, TCompany> : EntityTypeConfiguration<TProduct> 
    where TProduct : Product<TCompany> 
    where TCompany : Organization
{
    public ProductEntityTypeConfiguration() 
    {
        ...
        Property(_ => _.SomePropInternal)
            .IsRequired()
            .IsUnicode()
            .HasMaxLength(100);
    }
}

对于某些产品:

public class SomeProductMap : ProductEntityTypeConfiguration<SomeProduct, InsuranceCompany>
{
    public SomeProductMap()
    {
        ToTable("Business.SomeProduct");

        Property(_ => _.AnotherSomePropInternal)
            .IsRequired()
            .IsUnicode()
            .HasMaxLength(100);
    }
}

当我尝试使用这些映射添加迁移时,它会说SomePropInternal is not declared on the type SomeProduct.

如果我将其更改internal string SomePropInternalpublic string SomePropInternal迁移,则会创建。这就是问题所在。我不想暴露那必须是私有财产。

因为AnotherSomePropInternal一切正常internal
