Question

我正在尝试将外键保存在一行的两列中。出于某种原因，这表现得很糟糕，因为有些导航属性在我的表中显示为列...这是模型。我做错了什么？

 public class BorrowedPerson
    {
        public int BorrowedPersonID { get; set; }
        public Nullable<int> PersonID { get; set; }
        public Nullable<int> CompanyID { get; set; }
        public Nullable<int> TempCompanyID { get; set; }
        public virtual Person Person { get; set; }
        public virtual Company Company { get; set; }
        public virtual Company TempCompanyID { get; set; }
    }

我想通了......非常简单的回答。当您为同一类型指定多个导航属性时，它需要您手动指定外键，如此。

public class BorrowedPerson
    {
        public int BorrowedPersonID { get; set; }
        public Nullable<int> PersonID { get; set; }
        public Nullable<int> CompanyID { get; set; }
        public Nullable<int> TempCompanyID { get; set; }
        public virtual Person Person { get; set; }
        [ForeignKey("CompanyID ")]
        public virtual Company Company { get; set; }
        [ForeignKey("TempCompanyID")]
        public virtual Company TempCompanyID { get; set; }
    }

同一张桌子上有多个外键？
