C# 代码优先实体框架Asp.net MVC

我有个问题。我创建了一些模型来生成数据库，但有一个问题。当它生成数据库时，引用2

Album\u id

to one

Audio\u songs

专辑型号对我来说似乎很合适，但我不确定。 如果您看到由C生成的Sql查询，它具有

Album\u id

和

Albums\u 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; }

在您的音频歌曲模型中，您添加了两次专辑模型{get；set；}。一个有

相册

，一个有

类别

。这是问题的原因吗？是的，您有一个模型错误：

public virtual Album Category{get；set；}
