实体类型'AdminServiceCenter'和'ManagerServiceCenter'不能共享表'SrvCenters'

Question

我创建了两个班级。

[Table("SrvCenters")]
public class ManagerServiceCenter
{
    #region Public Properties

    /// <summary>
    /// Gets or sets the srv center id.
    /// </summary>
    [Key]
    public int SrvCenterId { get; set; }

    /// <summary>
    /// Gets or sets the branch id.
    /// </summary>
    public int BranchId { get; set; }

    /// <summary>
    /// Gets or sets the branch.
    /// </summary>
    public virtual Branch Branch { get; set; }

    /// <summary>
    /// Gets or sets the location id.
    /// </summary>
    public int LocationId { get; set; }

    /// <summary>
    /// Gets or sets the location.
    /// </summary>
    public virtual Location Location { get; set; }

    /// <summary>
    /// Gets or sets the description.
    /// </summary>
    public string Description { get; set; }

    /// <summary>
    /// Gets or sets the domain name.
    /// </summary>
    public string DomainName { get; set; }

    /// <summary>
    /// Gets or sets the active.
    /// </summary>
    public int Active { get; set; }

    #endregion
}

和

[Table("SrvCenters")]
public class AdminServiceCenter
{
    #region Public Properties

    /// <summary>
    /// Gets or sets the srv center id.
    /// </summary>
    [Key]

    public DateTime? CreateTime { get; set; }

    /// <summary>
    /// Gets or sets the create user.
    /// </summary>
    public string CreateUser { get; set; }

    /// <summary>
    /// Gets or sets the cust priority id.
    /// </summary>
    public int CustPriorityId { get; set; }

    /// <summary>

    /// </summary>
    public int CustomerBindId { get; set; }

    /// <summary>
    /// Gets or sets the delete count.
    /// </summary>
    public int DeleteCount { get; set; }

    /// <summary>
    /// Gets or sets the delete time.
    /// </summary>
    public int DeleteTime { get; set; }

    /// <summary>
    /// Gets or sets the description.
    /// </summary>
    public string Description { get; set; }

    /// <summary>

    /// </summary>
    public string DomainName { get; set; }

    /// <summary>
    /// Gets or sets the end break.
    /// </summary>
    public TimeSpan EndBreak { get; set; }

    /// <summary>
    /// Gets or sets the end day.
    /// </summary>
    public TimeSpan EndDay { get; set; }

    /// <summary>
    /// Gets or sets a value indicating whether estimate wait time.
    /// </summary>
    public int EstimateWaitTime { get; set; }

    /// <summary>
    /// Gets or sets a value indicating whether have break.
    /// </summary>
    public int HaveBreak { get; set; }

    /// <summary>
    /// Gets or sets the hold order.
    /// </summary>
    public int HoldOrder { get; set; }

    /// <summary>
    /// Gets or sets the location id.
    /// </summary>
    public int LocationId { get; set; }

    /// <summary>
    /// Gets or sets the notif interval.
    /// </summary>
    public int NotifInterval { get; set; }

    /// <summary>
    /// Gets or sets a value indicating whether notification.
    /// </summary>
    public int Notification { get; set; }

    /// <summary>
    /// Gets or sets the priority direct id.
    /// </summary>
    public int PriorityDirectId { get; set; }

    /// <summary>
    /// Gets or sets the serv priority id.
    /// </summary>
    public int ServPriorityId { get; set; }

    /// <summary>
    /// Gets or sets the service bind id.
    /// </summary>
    public int ServiceBindId { get; set; }

    /// <summary>
    /// Gets or sets the srv center guid.
    /// </summary>
    public Guid SrvCenterGuid { get; set; }

    /// <summary>
    /// Gets or sets the sequence id.
    /// </summary>
    public int SequenceId { get; set; }

    /// <summary>
    /// Gets or sets the sequence.
    /// </summary>
    public virtual Sequence Sequence { get; set; }

    #endregion
}

尝试时我调用了ManagerServiceCenter。我得到了例外

  

实体类型'AdminServiceCenter'和'ManagerServiceCenter'不能共享表'SrvCenters'，因为它们不在同一类型层次结构中，或者没有有效的一对一外键关系，它们之间具有匹配的主键。

如果您想在两个实体之间共享表格，则必须使用TPH inheritance或table splitting。
