当我询问 PackageId 时，为什么会返回 MemberId？

Question

创建描述 model 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 package model

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 controller 和视图。 在默认的“创建”视图中，当我尝试时，PackageId 将作为授权用户的 MemberID 出现。

@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>

以上是导致 label 实际显示“PackageId”的视图，但下拉菜单 (ViewBag.PackageId) 实际上是登录用户的 MemberID，即 Package 和描述。

我的代码怎么错了？

Answer 1

“ViewBag.PackageId”是显而易见的答案，应该引用 MemberId。
