创建描述模型后：

public class Descriptionmodel
{
    [Key]
    public int DescriptionId { get; set; }

    public int PackageId { get; set; }

    [Required]
    [StringLength(255)]
    public string DescriptionFull { get; set; }


    // Each description must be attached to 1 package
    [ForeignKey("PackageId")]
    public virtual PackageModel PackageModel { get; set; }

}

和包装型号

public class PackageModel
{

    [Key]
    public int PackageId { get; set; }

    [DisplayName("Package Name")]
    [Required]
    public string PName { get; set; }

    [DisplayName("Location")]
    [Required]
    public string PLocation { get; set; }

    [Required]
    [DataType(DataType.Currency)]
    [Column(TypeName = "money")]
    public decimal Price { get; set; }

    [DisplayName("active")]
    public bool Isactive { get; set; }

    [ForeignKey("MemberId")]
    public virtual AgentModel AgentModel { get; set; }

    [Required]
    public string MemberId { get; set; }


    public virtual ICollection<Descriptionmodel> Descriptions { get; set; }

    [DisplayFormat(NullDisplayText = "Not reviewed")]
    public virtual ICollection<ReviewModel> Reviews { get; set; }
}

然后我使用脚手架创建默认的控制器和视图。在默认的“创建”视图中，当我尝试时，PackageId会显示为授权用户的MemberID。

@model final1.Models.Descriptionmodel
...redacted create.cshtml...
div class="form-group">
    <label asp-for="PackageId" class="control-label"></label>
    <select asp-for="PackageId" class ="form-control" asp-items="ViewBag.PackageId"></select>
</div>

上图是导致标签实际显示“ PackageId”的视图，但是下拉列表（ViewBag.PackageId）实际上是已登录用户的Package和Description的MemberID。

我的代码有什么错误？
