如何在mvc5的AspNetUsers中添加外键引用

本文关键字：添加 引用 AspNetUsers mvc5 | 更新日期: 2023-09-27 18:18:22

谁来帮帮我!我有一个名为Student的Model类。现在我需要用"StudentID"保存一个用户。"StudentID"将作为外键保存在用户表中。这是我的学生班

public class Student
{
    public int ID { get; set; }
    public string LastName { get; set; }
    public string FirstMidName { get; set; }
    public int? DepID { get; set; }
    public DateTime EnrollmentDate { get; set; }
    [ForeignKey("DepID")]
    public virtual Department Department { get; set; }
    public virtual ICollection<Enrollment> Enrollments { get; set; }
}
我的身份模型是 
public class ApplicationUser : IdentityUser
{
}
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {
    }
    public DbSet<Student> Students { get; set; }
    public DbSet<Enrollment> Enrollments { get; set; }
    public DbSet<Course> Courses { get; set; }
    public DbSet<Department> Departments { get; set; }
    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }
}

那么我如何添加"studentID"到用户表作为外键

如果您只是想使用StudenID作为另一个表中的外键，您可以这样做，例如

 public class Employee
  {
    [Key]
    public int EmployeeID { get; set; }
    public string Name { get; set; }
    public virtual EmployeeDetail EmployeeDetail { get; set; }
  }
public class EmployeeDetail
  {
    [Key]
    [ForeignKey("Employee")]
    public int EmployeeID { get; set; }
    public string Adress { get; set; }
    public virtual Employee Employee { get; set; }
  }

如果您谈论的是Asp. xml创建的实际User表。Net Identity，那么您可以简单地扩展和定制User表:
