代碼優先實體框架Asp.net MVC

Question

我有一個問題。 我創建了一些模型來生成數據庫，但是有一個問題。 生成數據庫時，它將兩個Album_id引用到一個Audio_songs

專輯模型對我來說似乎不錯，但我不確定。 如果看到由C＃生成的Sql查詢，它具有Album_id和Albums_id

    .ForeignKey("dbo.Albums", t => t.Albums_Id)
            .ForeignKey("dbo.Albums", t => t.Category_Id) 



 - Album_id  
 - Albums_id



           public class Album
            {
                [Key]
                public int Id { get; set; }
                [Required]
                public string Name { get; set; }
                public string About { get; set; }
                public string Folder { get; set; }
                public bool Approve { get; set; }
                public string Picture { get; set; }
                public System.DateTime CreateDate { get; set; }
                public virtual ICollection<AudioSong> AudioSongs { get; set; }
                public virtual ICollection<Category> Categories { get; set; }
                public virtual ICollection<Tag> Tags { get; set; }
                public bool IsHomePage { get; set; }
                public bool Featured { get; set; }
            }

      public class AudioSong
        {
            [Key]
            public int Id { get; set; }
            [Required]
            public string Name { get; set; }
            public string Url { get; set; }
