entity-framework - 将对象列表作为外键

Question

如果我有两个类:

 public class Event
    {
        public int EventId { get; set; }
        public string EventName { get; set; }

    }

和

public class Dog
    {
        public int DogId { get; set; }
        public string Name { get; set; }
        public int Age { get; set; }
    }

我希望我的 event 类能够附加一个 dog 列表。我怎样才能让我的事件类明白我希望它能够包含狗的列表？我正在使用 Entity Framework 。谢谢!

假设您使用代码优先:

public class Event
{
    public int EventId { get; set; }
    public string EventName { get; set; }

    public virtual ICollection<Dog> Dogs { get; set; }
}

public class Dog
{
    public int DogId { get; set; }

    [ForeignKey("Event")]
    public int EventID { get; set; }

    public string Name { get; set; }

    public int Age { get; set; }

    public virtual Event Event { get; set; }
}
