问:您能告诉我为什么它会在Bank_Id
表格中创建Bank_Id1
和IpForeclosureActionHeaders
列吗? B'cose我已将这些列命名为BankId
和AssignedToBankId
。我怎么能避免呢?提前致谢。
答案 0 :(得分:3)
您可以阅读此主题 - 它的情况大致相同:Why is EF code-first generating an extraneous foreign key column?
InverseProperty
将帮助您避免这种不必要的引用。
解决方案:
[ForeignKey("BankId")]
[InverseProperty("ForeclosureActionHeaders")]
public virtual Bank Bank { get; set; }
public virtual int BankId { get; set; }
[ForeignKey("AssignedToBankId")]
[InverseProperty("AssignedToBankForeclosureActionHeaders")]
public virtual Bank AssignedToBank { get; set; }
public virtual int AssignedToBankId { get; set; }
