Question

我尝试从Controller渲染我的列表视图，但它显示错误。我确认桌子不是空的。

控制器如下所示：

控制器

        public ActionResult Index()
    {
        var prbmembershipLists = prbmembershipRepo.PrbMembershipIndex();
        return View(prbmembershipLists);
    }

以下是错误指向第23行的存储库

存储库

        public List<PrbMembershipViewModel> PrbMembershipIndex()
    {
        var listofprbmembership = entity.PRB_MEMBERSHIP_TYPE.Where(c => c.ACTION_STATUS != 2).ToList();   //Where(c => c.ACTION_STATUS != 2).
        List<PrbMembershipViewModel> PrbMembershiplistfromModel = new List<PrbMembershipViewModel>();
        foreach (var prbmerbershipItem in listofprbmembership)
        {
            PrbMembershipViewModel modelObj = new PrbMembershipViewModel()
            {
                PRB_MEMBERSHIP_TYPE_ID = prbmerbershipItem.PRB_MEMBERSHIP_TYPE_ID,
                PRB_MEMBERSHIP_TYPE_NAME = prbmerbershipItem.PRB_MEMBERSHIP_TYPE_NAME,
                PRB_ID = prbmerbershipItem.PRB_ID,
                Prb = prbmerbershipItem.PRB.PRB_NAME,
                ACTION_STATUS = (int)prbmerbershipItem.ACTION_STATUS,
                CREATED_BY = prbmerbershipItem.CREATED_BY,
                CREATED_DATE = prbmerbershipItem.CREATED_DATE,
                DELETED_BY = prbmerbershipItem.DELETED_BY,
                DELETED_DATE = prbmerbershipItem.DELETED_DATE,
                LAST_UPDATE_BY = prbmerbershipItem.LAST_UPDATE_BY,
                LAST_UPDATE_DATE = prbmerbershipItem.LAST_UPDATE_DATE
            };
            PrbMembershiplistfromModel.Add(modelObj);
        }
        return PrbMembershiplistfromModel;
    }

我的视图如下所示

查看

@model IEnumerable<BPP.CCSP.Admin.Web.ViewModels.PrbMembershipViewModel>

@{
 //Layout = null;
}

<div class="box box-primary box-body">
<table class="table table-striped table-bordered" id="dtaTable">
    <thead class="dataTableHead">
    @{
        var i = 1;
    }

    @foreach (var item in Model)
    {
        <tr id="row_@item.PRB_MEMBERSHIP_TYPE_ID">
            <td>@i</td>
            <td>
                @Html.DisplayFor(modelItem => item.PRB_MEMBERSHIP_TYPE_NAME)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.Prb)
            </td>
            <td>

            </td>

            <td>

            </td>
        </tr>
        i = i + 1;
    }

</table>

<div class="modal fade" id="myModal">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <a href="#" class="close" data-dismiss="modal">&times;</a>
                <h3 class="modal-title">Delete PRB membership Type</h3>
            </div>
            <div class="modal-body">
                <h4>Are you sure you wish to delete this PRB Membership Type? </h4>

                <div style="text-align:center;display:none" id="loaderDiv">
                    @*<img src="~/Content/InternetSlowdown_Day.gif" width="150" />*@
                    <img src="~/Content/images/ajax-loader.gif" width="60" />
                </div>

            </div>
            <div class="modal-footer">
                <a href="#" class="btn btn-default" data-dismiss="modal">Cancel</a>
                <a href="#" class="btn btn-success" onclick="DeletePrbMembership()">Confirm</a>
            </div>

        </div>

    </div>

</div>

@*hidden field for storing current PRB_MEMBERSHIP_TYPE_ID*@
<input type="hidden" id="hiddenPrbMembershipId" />

请问我该如何解决这个问题。

由于

ASP.NET MVC - 未在列表视图中将对象引用设置为对象的实例
