部分视图错误对象引用未设置为对象的实例。 MVC4 剃刀

Question

我正在做一个项目，为使用 MVC4 和 Razor 的学校创建 CMS。我需要在索引上创建一个局部视图（用于最新新闻和员工）并为每个模型获取最多 5 条记录我在我的共享文件夹中创建了一个局部视图但我一直收到这样的错误消息

异常详细信息：System.NullReferenceException：对象引用未设置为对象的实例。

Line 1:  @model IEnumerable<MvcDale.Models.StaffModels>
Line 2:  @foreach ( var staff in Model ){
Line 3:      <div class="wrapper p4-1">
Line 4:          <figure class="img-indent3 box1">

源文件：c:\Users\Hammed\Documents\Visual Studio 2010\Projects\MvcDale\MvcDale\Views\Shared_StaffListPartial.cshtml 行：2

这就是我的局部视图文件的样子

@model IEnumerable<MvcDale.Models.StaffModels>
@foreach ( var staff1 in Model ){
    <div class="wrapper p4-1">
        <figure class="img-indent3 box1">
            <img src="@Url.Content(staff1.Picture)" alt="">
        </figure>
        <div class="extra-wrap">
            <h6><a href="#">@staff1.title @staff1.sname @staff1.oname @staff1.fname</a></h6>
            @staff1.profile 
        </div>
    </div>
    }
}

从我的主页索引视图中，我可以像这样调用它

{
   @Html.Partial("~/Views/Shared/_StaffListPartial.cshtml")
}

谁能帮助我或向我建议我的代码有什么问题。第一次做 ASP.net MVC。谢谢

这是我的 staffModel 类

using System.Data.Entity;

namespace MvcDale.Models
{
    [Table("Staff")]
    public class StaffModels
    {
        [Key]
        [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
        public int staff_id { get; set; }
        public string title { get; set; }
        public string fname {get; set;}
        public string sname {get; set;}
        public string oname {get; set;}
        public string phone { get; set; }
        public string email { get; set; }
        public string profile { get; set; }
        public string Picture { get; set; }

    }
}

这是我来自 ~/views/home/index 的 index.cshtml

@{ Layout = "~/Views/Shared/_LayoutPage1.cshtml"; }


@{
    ViewBag.Title = "Home Page";
    var Content = ViewBag.Content;
}

@section feature {

@Content;

                            </div>
}

@section staff_{
<h3 class="p3-1">our staff</h3>
 @model MvcDale.Models.GenModels
    @foreach ( var staff1 in Model.Staff)
    {
        @Html.Partial("~/Views/Shared/_StaffListPartial.cshtml", staff1)

    }                                                                                       

                                <a href="#" class="link">view all</a>

}

因为这是我的员工空间视图，我打算从

生成一个 5（最多）的列表

@model MvcDale.Models.StaffModels

    <div class="wrapper p4-1">
        <figure class="img-indent3 box1">
            <img src="@Url.Content(Model.Picture)" alt="">
        </figure>
        <div class="extra-wrap">
            <h6><a href="#">@Model.title @Model.sname @Model.oname @Model.fname</a></h6>
            @Model.profile 
        </div>
    </div>

这就是我打算归档的内容 所有模型和 dbcontext 都是为了我已经可以粗略的 db 表

您必须像这样在 Html.Partial 调用中为您的局部视图指定模型

@Html.Partial("~/Views/Shared/_StaffListPartial.cshtml", Model.StaffModelsList)
