C# 使用同一个表的两个外键构建模型

假设我有一个

用户

模型，现在我想添加一个

朋友

模型。我想命名我的FK字段

RequestorID

和

ResponderID

。我需要什么样的数据注释或fluent-api映射来实现这一点并防止EF自动生成自己的列

public class Friend
{
    public int FriendID { get; set; }
    public int RequestorID { get; set; }
    public int ResponderID { get; set; }
    public int FriendStatusID { get; set; }
    public DateTime User1RequestDate { get; set; }
    public DateTime User2ResponseDate { get; set; }
    public virtual FriendStatus FriendStatus { get; set; }


    public virtual User Requestor { get; set; }
    public virtual User Responder { get; set; }

}

试试这个

public class Friend
    {
        public int FriendID { get; set; }
        public int RequestorID { get; set; }
        public int ResponderID { get; set; }
        public int FriendStatusID { get; set; }
        public DateTime User1RequestDate { get; set; }
        public DateTime User2ResponseDate { get; set; }
        public virtual FriendStatus FriendStatus { get; set; }

        [ForeignKey("RequestorID")] //fixed
        public virtual User Requestor { get; set; }
        [ForeignKey("ResponderID")]
        public virtual User Responder { get; set; }
    }

您在第一个数据批注上有语法错误，但仍然有效。谢谢
