Question

我有以下内容：

映射：

  modelBuilder.Entity<CostCentreCopy>().Property(p => p.CostCentreId).HasColumnName("ID_COST_CENTRE").HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);

    modelBuilder.Entity<CostCentreCopy>().HasRequired(e => e.Address).WithRequiredDependent(a => a.CostCentreCopy);
    modelBuilder.Entity<CostCentreAddress>().HasRequired(e => e.CostCentreCopy).WithRequiredPrincipal(a => a.Address);

    modelBuilder.Entity<CostCentreAddress>().Property(p => p.CostCentreId).HasColumnName("ID_COST_CENTRE").HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity);
    modelBuilder.Entity<CostCentreAddress>().Property(p => p.Address1).HasColumnName("TX_ADDRESS_1").IsRequired();
    modelBuilder.Entity<CostCentreAddress>().Property(p => p.Address2).HasColumnName("TX_ADDRESS_2").IsRequired();
    modelBuilder.Entity<CostCentreAddress>().Property(p => p.City).HasColumnName("TX_CITY").IsRequired();
    modelBuilder.Entity<CostCentreAddress>().Property(p => p.State).HasColumnName("TX_STATE").IsRequired();
    modelBuilder.Entity<CostCentreAddress>().Property(p => p.Country).HasColumnName("TX_COUNTRY").IsRequired();
    modelBuilder.Entity<CostCentreAddress>().Property(p => p.Postcode).HasColumnName("TX_POST_CODE").IsRequired();

    modelBuilder.Entity<CostCentreAddress>().ToTable("MIC_COST_CENTRE_COPY");
    modelBuilder.Entity<CostCentreCopy>().ToTable("MIC_COST_CENTRE_COPY");

型号：

public  class CostCentreCopy
    {
        [Key]
        public int CostCentreId { get; set; }


        public virtual CostCentreAddress Address { get; set; }
    }

    public class CostCentreAddress
    {
        [Key]
        public int CostCentreId { get; set; }

        public string Address1 { get; set; }
        public string Address2 { get; set; }
        public string Country { get; set; }
        public string City { get; set; }
        public string Postcode { get; set; }
        public string State { get; set; }

        public virtual CostCentreCopy CostCentreCopy { get; set; }
    }

有了这个，我可以使用地址详细信息保存所有CostCentreCopy。但是，当我通过Id获得CostCentreCopy时，我只获得CostCentreCopy而不是地址。

该表是一个带有标识列的平面表。

有没有办法使用EF在主表作为标识的表上使用表拆分来创建，返回，更新和删除。

在您的关系船中定义虚拟时

public virtual CostCentreAddress Address { get; set; }

它被评估为延迟加载的候选者，因此您可以明确说出.Include（c c =＆gt; Address）或删除虚拟关键字。

如果这有助于别忘了将其标记为答案：）
