用兩個外鍵創建模型到同一個表

Question

可以說我有一個User模型，現在我想添加一個Friend模型。我想命名我的FK字段RequestorID和ResponderID。什麼數據註釋或流利的api映射我需要做到這一點，並防止EF自動生成自己的列？

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; } 

}

試試這個

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; } 
    }
