c# – 同一个表的EF Code First Duplicate Foreign Key

我一直在阅读有关EF Code First生成重复外键的SO帖子,并尝试将解决方案应用于我的代码但无法修复我的代码.

这是我的课程

public class Schedule
{
    public int Id { get; set; }
    public ICollection<Appointment> Appointments { get; set; }
}

public class Appointment
{
    public int Id { get; set; }
    public Schedule Schedule { get; set; }
}

public class ScheduleConfiguration : EntityTypeConfiguration<Schedule>
{
    public ScheduleConfiguration()
    {
        HasKey(s => s.Id);
        Property(s => s.Id).HasColumnName("SCHEDULEID");            
        ToTable("SCHEDULES");
    }        
}

public class AppointmentConfiguration : EntityTypeConfiguration<Appointment>
{
    public AppointmentConfiguration()
    {
        HasKey(a => a.Id);
        Property(a => a.Id).HasColumnName("APPOINTMENTID");            
        Hasrequired(a => a.Schedule).WithMany().Map(x => x.MapKey("SCHEDULEID"));
        ToTable("APPOINTMENTS");
    }
}

这在约会表中生成两个外键,即SCHEDULEID和Schedule_Id1.

如何告诉EF不要创建Schedule_Id1

解决方法

试试这个：

Hasrequired(a => a.Schedule).WithMany(x=> x.Appointment).Map(x => x.MapKey("SCHEDULEID"));

希望这有帮助.
