Question

我之间有一对多和多对多的关系：

public class User
{
    [Key]
    public Guid UserId { get; set; }
    public string Address { get; set; }
    public double Latitude { get; set; }
    public double Longitude { get; set; }
    public string Units { get; set; }
    public int Distance { get; set; }

    public List<Sport> Sports { get; set; }

    [InverseProperty("UserCreatorId")]
    public ICollection<Event> EventsCreated { get; set; }

    [InverseProperty("Users")]
    public ICollection<Event> Events { get; set; }

    public ICollection<Comment> Comments { get; set; }
}

和

public class Event
{
    [Key]
    public int EventId { get; set; }
    public string SportName { get; set; }
    public string Explanation { get; set; }

    [Required]
    public string Address { get; set; }
    public double Latitude { get; set; }
    public double Longitude { get; set; }

    public bool Active { get; set; }
    public int NumUsersJoined { get; set; }
    [Required, Range(2,50, ErrorMessage = "Must be between 2 and 50")]
    public int MaxNumUsers { get; set; }

    public Guid UserCreatorId { get; set; }    

    public ICollection<User> Users { get; set; }

    public ICollection<Comment> Comments { get; set; }
}

多对多的关系它工作正常，但是1：很多不是，它在事件表User_UserId中的数据库中创建了一个额外的列，并使其成为外键而不是我想要的UserCreatorId。我做错了什么？

Answer 1

尝试这样做，

<{1>}中的

，

Event

和，在[ForeignKey("UserCreator")] public Guid UserCreatorId { get; set; } public User UserCreator{ get; set; } [InverseProperty("Events")] public ICollection<User> Users { get; set; }

User

同一型号中的一对多+多对多
