在我的架构设计中，我有 2 个表，它们由 2 个不同的键关联。我知道当它们是表的“Id”成员时，EF 如何神奇地创建外键，但我不太明白如何创建第二个关系。

注意：这个模式实际上还不存在；我将使用 codefirst 来创建它。

这是我正在尝试做的简单图表（粉红色的关系是我不确定如何在 codefirst 中实现的关系） NewClub.Id 是主键，所有 NEW_CLUB_ID 都是它的外键粉红色突出显示的列是相关的，但不是唯一的： 在此处输入图像描述

    namespace NCB.Models
    {
     public  sealed class NewClub
     {


        public NewClub()
        {
            //Related tables here
            NewClubRecruitingTeams = new List<NewClubRecruitingTeam>();
            NewClubRecruitingTeamDates = new List<NewClubRecruitingTeamDate>();

        }

        //Primary Key
        public int Id { get; set; }

        //Club Info
        public string CreatorMasterCustomerId { get; set; }
        public string ClubMasterCustomerId { get; set; }
        public bool IsConverted { get; set; }
        public string NewClubName { get; set; }
        public string NewClubLocation { get; set; }
        public string NewClubType { get; set; }
        public DateTime? DateCreated { get; set; }
        public DateTime? DateUpdated { get; set; }


        // Related tables here
        public virtual List<NewClubRecruitingTeam> NewClubRecruitingTeams { get; set; }
        public virtual List<NewClubRecruitingTeamDate> NewClubRecruitingTeamDates { get; set; }

     }

     public class NewClubRecruitingTeamDate
    {
        //Primary Key
        public int Id { get; set; }
        //Foriegn Keys
        public int NewClubId { get; set; }
        public int NewClubRecruitingTeamTeamNumber { get; set; }

        public DateTime? StartDateTime { get; set; }
        public DateTime? EndDateTime { get; set; }
        public DateTime? DateCreated { get; set; }
        public DateTime? DateUpdated { get; set; }

        public NewClub NewClub { get; set; }
        public NewClubRecruitingTeam NewClubRecruitingTeam { get; set; }
    }

     public class NewClubRecruitingTeam
    {
        //Primary Key
        public int Id { get; set; }
        //Foreign Key
        public int NewClubId { get; set; }

        public int TeamNumber { get; set; }
        public string TeamMemberName { get; set; }
        public string TeamMemberEmail { get; set; }
        public string TeamMemberPhone { get; set; }
        public DateTime? DateCreated { get; set; }
        public DateTime? DateUpdated { get; set; }

        public NewClub NewClub { get; set; }


      }
   }
