通过数据注释与同一个表建立多个关系,首先使用代码
我有以下模型:
public class Member
{
public int Id { get; set; }
public string Username { get; set; }
public int MainEmailId { get; set; }
public virtual Email MainEmail { get; set; }
public virtual ICollection<Email> MemberEmails { get; set; }
}
public partial class Email
{
public Int32 Id { get; set; }
public String Email { get; set; }
public int MemberId { get; set; }
public virtual Member Member { get; set; }
}
如您所见,我希望创建一个: 会员与会员电子邮件(主要电子邮件地址)之间的一对一关系 从会员到会员电子邮件的一对多关系
我知道如何使用 Code First Fluent API 来做到这一点。不过,我只需要使用 DataAnnotations 来完成此操作。这可能吗?
多谢。
I have the following model:
public class Member
{
public int Id { get; set; }
public string Username { get; set; }
public int MainEmailId { get; set; }
public virtual Email MainEmail { get; set; }
public virtual ICollection<Email> MemberEmails { get; set; }
}
public partial class Email
{
public Int32 Id { get; set; }
public String Email { get; set; }
public int MemberId { get; set; }
public virtual Member Member { get; set; }
}
As you can see I wish to create a:
one-to-one relation from the Member to MemberEmail (the main email address)
one-to-many relation from Member to MemberEmail
I know how to do this with Code First Fluent API. However I need to do it with DataAnnotations only. Is this possible?
Thanks a lot.
