Question

我有以下实体：

public class Application 
{
   [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
   public override int Id { get; set; }
   public ApplicationSubcontractors ApplicationSubcontractors{get; set;}
}

public class ApplicationSubcontractors
{
   public ApplicationId {get; set;}
   public Application Application {get; set;}
}

我想对此进行映射，以便Application有ApplicationSubcontractors且ApplicationSubcontractors有Application：

我如何将这一对比模型化？

Application实体是否存在Id主键这一事实？

Answer 1

您可以执行以下操作：

public class Application 
{
    public int Id { get; set; }

    public virtual ApplicationSubcontractor ApplicationSubcontractor { get; set; }
}


public class ApplicationSubcontractor
{
    [Key, ForeignKey("Application")]
    public override int Id { get; set; }

    public virtual Application Application { get; set; }
}
