如何将常量传递给外键属性？

Question

我有一个带有复合键和复合外键的模型。是否可以将常量而不是列名传递给外键注释？

当前型号：

[Table("PBDS.INTERACTIONS")]
public partial class Interaction
{
    // NOTE: The primary key for the INTERACTIONS table is a composite key
    //       consisting of:
    //           - ACCOUNT_ID
    //           - CONTACT_DATE
    //           - CONTACT_SEQ
    //           - PAGE

    [Key]
    [Column("ACCOUNT_ID", Order = 0)]
    public int ACCOUNT_ID { get; set; }

    [Key]
    [Column("CONTACT_DATE", Order = 1)]
    public DateTime CONTACT_DATE { get; set; }

    [Key]
    [Column("CONTACT_SEQ", Order = 2)]
    public int CONTACT_SEQ { get; set; }

    [Key]
    [Column("PAGE", Order = 3)]
    public int PAGE { get; set; }

    [ForeignKey("ACCOUNT_ID,CONTACT_DATE,CONTACT_SEQ,PAGE,DATA_VALUE")]
    public InteractionData InteractionData { get; set; }

}

DATA_VALUE在我看来将始终是一个常量。理想情况下，我希望我可以进行这样的外键设置：

所需模型：

[Table("PBDS.INTERACTIONS")]
public partial class Interaction
{
    // NOTE: The primary key for the INTERACTIONS table is a composite key
    //       consisting of:
    //           - ACCOUNT_ID
    //           - CONTACT_DATE
    //           - CONTACT_SEQ
    //           - PAGE

    [Key]
    [Column("ACCOUNT_ID", Order = 0)]
    public int ACCOUNT_ID { get; set; }

    [Key]
    [Column("CONTACT_DATE", Order = 1)]
    public DateTime CONTACT_DATE { get; set; }

    [Key]
    [Column("CONTACT_SEQ", Order = 2)]
    public int CONTACT_SEQ { get; set; }

    [Key]
    [Column("PAGE", Order = 3)]
    public int PAGE { get; set; }

    [ForeignKey("ACCOUNT_ID,CONTACT_DATE,CONTACT_SEQ,PAGE,<Net_Cost_Constant_String>")]
    public InteractionData NetCost { get; set; }

    [ForeignKey("ACCOUNT_ID,CONTACT_DATE,CONTACT_SEQ,PAGE,<Airing_Phone_Constant_String>")]
    public InteractionData AiringPhone { get; set; }

    [ForeignKey("ACCOUNT_ID,CONTACT_DATE,CONTACT_SEQ,PAGE,<RepFirm_Constant_String>")]
    public InteractionData RepFirm { get; set; }

    [ForeignKey("ACCOUNT_ID,CONTACT_DATE,CONTACT_SEQ,PAGE,<Week_Day_Constant_String>")]
    public InteractionData WeekDay { get; set; }

}

请注意， DATA_VALUE 中有130个唯一值，但我只想在此处列出4个。

这可能吗？也欢迎使用其他方法。
