顯示已付每年會費的MemberOrg列表？

在我MVC5應用程序，我目前正在處理2個表：顯示已付每年會費的MemberOrg列表？

[MemberDues] -- [Id], [Year], [Display], [Amount] 

[MemberDuesReceived] -- [Id], [MemberDuesId], [MemberOrgId], [PaidByUserId], [TransactionId], [Paid], [DatePaid], [PaymentMethod], [PayPalPaymentId], [PayPalPayerId], [PayPalPaymentState]

我有一個觀點（見下文），我顯示不同[MemberDues]記錄：

@model IEnumerable<PROJECTdev.Models.MemberDues> 

<script type="text/javascript" src="~/Areas/Admin/Scripts/Dues/Index.min.js"></script> 
<div id="alert" style="display: none;"></div> 

<table class="table table-striped"> 
    <thead> 
     <tr> 
      <th class="col-md-2"> 

      </th> 
      <th> 
       @Html.DisplayNameFor(model => model.Year) 
      </th> 
      <th> 
       @Html.DisplayNameFor(model => model.Display) 
      </th> 
      <th> 
       @Html.DisplayNameFor(model => model.Amount) 
      </th> 
      <th>View</th> 
     </tr> 
    </thead> 
    <tbody> 
     @foreach (var item in Model) 
     { 
      <tr> 
       <td> 
        <a href="MemberDuesManage/Edit/@item.Id" class="btn btn-success btn-sm noDecoration"><span class="glyphicon glyphicon-pencil"></span> Edit</a> 
        <a href="MemberDuesManage/Delete/@item.Id" class="btn btn-default btn-sm noDecoration"><span class="glyphicon glyphicon-floppy-remove"></span> Delete</a> 
       </td> 
       <td> 
        @Html.DisplayFor(modelItem => item.Year) 
       </td> 
       <td> 
        @Html.EditorFor(modelItem => item.Display, new { htmlAttributes = new { @class = "form-control pull-left", style = "height: 20px; width: 20px;", onclick = "disableEnableDues(" + item.Id + ", this)" } }) 
       </td> 
       <td> 
        @Html.DisplayFor(modelItem => item.Amount) 
       </td> 
       <td> 
        <a href="~/Admin/MemberDuesManage/DuesPaidMembers/@item.Id" class="btn btn-default btn-sm noDecoration"><span class="glyphicon glyphicon-list-alt"></span> Paid</a> 
       </td> 
      </tr> 
     } 
    </tbody> 
</table>

什麼，我試圖do有，當點擊[Paid]按鈕（鏈接）時，會出現一個列出所有已付會費的會員組織的視圖。爲此，我必須查詢[MemberDuesReceived]以獲得合適的[MemberDuesId]，並返回所有匹配的記錄[MemberDuesId] & [Paid] == true。這是我曾嘗試以下：

public async Task<ActionResult> DuesPaidMembers(int id) 
{ 
    MemberDues memberDues = await db.MemberDues.FindAsync(id); 
    return View(db.MemberDuesReceived.Where(mdr => mdr.MemberDuesId == memberDues.Id && mdr.Paid).ToListAsync()); 
}

然後，我創建了一個名爲DuesPaidMembers.cshtml視圖，低於：

@model IEnumerable<PROJECTdev.Models.MemberDuesReceived> 

@{ 
    ViewBag.Title = "DuesPaidMembers"; 
    Layout = "~/Areas/Admin/Views/Shared/_LayoutAdmin.cshtml"; 
} 

<h2>DuesPaidMembers</h2> 

<p> 
    @Html.ActionLink("Create New", "Create") 
</p> 
<table class="table"> 
    <tr> 
     <th> 
      @Html.DisplayNameFor(model => model.MemberDues.Id) 
     </th> 
     <th> 
      @Html.DisplayNameFor(model => model.MemberOrganization.Name) 
     </th> 
     <th> 
      @Html.DisplayNameFor(model => model.PaidByUser.Name) 
     </th> 
     <th> 
      @Html.DisplayNameFor(model => model.TransactionId) 
     </th> 
     <th> 
      @Html.DisplayNameFor(model => model.Paid) 
     </th> 
     <th> 
      @Html.DisplayNameFor(model => model.DatePaid) 
     </th> 
     <th> 
      @Html.DisplayNameFor(model => model.PaymentMethod) 
     </th> 
     <th> 
      @Html.DisplayNameFor(model => model.PayPalPaymentId) 
     </th> 
     <th> 
      @Html.DisplayNameFor(model => model.PayPalPayerId) 
     </th> 
     <th> 
      @Html.DisplayNameFor(model => model.PayPalPaymentState) 
     </th> 
     <th></th> 
    </tr> 

@foreach (var item in Model) { 
    <tr> 
     <td> 
      @Html.DisplayFor(modelItem => item.MemberDues.Id) 
     </td> 
     <td> 
      @Html.DisplayFor(modelItem => item.MemberOrganization.Name) 
     </td> 
     <td> 
      @Html.DisplayFor(modelItem => item.PaidByUser.Name) 
     </td> 
     <td> 
      @Html.DisplayFor(modelItem => item.TransactionId) 
     </td> 
     <td> 
      @Html.DisplayFor(modelItem => item.Paid) 
     </td> 
     <td> 
      @Html.DisplayFor(modelItem => item.DatePaid) 
     </td> 
     <td> 
      @Html.DisplayFor(modelItem => item.PaymentMethod) 
     </td> 
     <td> 
      @Html.DisplayFor(modelItem => item.PayPalPaymentId) 
     </td> 
     <td> 
      @Html.DisplayFor(modelItem => item.PayPalPayerId) 
     </td> 
     <td> 
      @Html.DisplayFor(modelItem => item.PayPalPaymentState) 
     </td> 
     <td> 
      @Html.ActionLink("Edit", "Edit", new { id=item.Id }) | 
      @Html.ActionLink("Details", "Details", new { id=item.Id }) | 
      @Html.ActionLink("Delete", "Delete", new { id=item.Id }) 
     </td> 
    </tr> 
} 

</table>

目前然而，當我按一下按鈕，我適當的控制器動作（）被稱爲，但是當線路return View(db.MemberDuesReceived.Where(mdr => mdr.MemberDuesId == memberDues.Id && mdr.Paid).ToListAsync());被命中，我收到以下錯誤：

The model item passed into the dictionary is of type 'System.Threading.Tasks.Task 1 [System.Collections.Generic.List 1[PRISMdev.Models.MemberDuesReceived]]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable 1 [PRISMdev.Models.MemberDuesReceived]」`

有沒有人有什麼想法，我顯然做錯了？

以下行是怪罪。

return View(db.MemberDuesReceived 
    .Where(mdr => mdr.MemberDuesId == memberDues.Id && mdr.Paid) 
    .ToListAsync());

你逝去的ToListAsync結果作爲你的模型，這是一個Task<List<PRISMdev.Models.MemberDuesReceived>>。

相反，插入await使運行任務所得List<PRISMdev.Models.MemberDuesReceived>類型的返回值是爲你的模型：

return View(await db.MemberDuesReceived 
    .Where(mdr => mdr.MemberDuesId == memberDues.Id && mdr.Paid) 
    .ToListAsync());
