如何将两列相乘并显示结果

How to multiply two columns and show the result

在我的应用程序中有一个 table 显示我从控制器传递的数据。

在最后一列中,我想通过将数量和单位数量数据相乘来显示总数量。

我可以得到帮助来做这个方法吗?提前致谢。

这是代码

<div class="row">
  <div class="col-12 table-responsive">
    <table class="table table-striped">
      <thead>
        <tr>
        <th>#</th>
        <th>Requesting Item</th>
        <th>Required Qty</th>
        <th>Unit Amount</th>
        <th>Total Amount</th>
        </tr>
      </thead>
        <tbody>
         @{int RowNo = 0;}
         @for (int i = 0; i < Model.First().PurchaseOrderItems.Count; i++)
          {
           <tr>
            <td>@{RowNo++;} @RowNo</td>
            <td>@Html.DisplayFor(Model => Model.First().PurchaseOrderItems[i].Item_Description)</td>
            <td>@Html.DisplayFor(Model => Model.First().PurchaseOrderItems[i].Qty)</td>
            <td>Rs.@Html.DisplayFor(Model => Model.First().PurchaseOrderItems[i].UnitAmount)</td>
            <td></td>
           </tr>
          }
        </tbody>
      </table>
     </div>
</div>

我会在您的控制器中处理计算,然后将该计算的输出设置为您模型上的新 属性(如 TotalAmountPurchasedOrderTotalAmount)。这将使它更容易在您的模板中呈现。

<div class="row">
  <div class="col-12 table-responsive">
    <table class="table table-striped">
      <thead>
        <tr>
        <th>#</th>
        <th>Requesting Item</th>
        <th>Required Qty</th>
        <th>Unit Amount</th>
        <th>Total Amount</th>
        </tr>
      </thead>
        <tbody>
         @{int RowNo = 0;}
         @for (int i = 0; i < Model.First().PurchaseOrderItems.Count; i++)
          {
           <tr>
            <td>@{RowNo++;} @RowNo</td>
            <td>@Html.DisplayFor(Model => Model.First().PurchaseOrderItems[i].Item_Description)</td>
            <td>@Html.DisplayFor(Model => Model.First().PurchaseOrderItems[i].Qty)</td>
            <td>Rs.@Html.DisplayFor(Model => Model.First().PurchaseOrderItems[i].UnitAmount)</td>
            <td></td>
           </tr>
          }
         <tr>
          <td colspan="4">Total Amount:</td>
          <td>Rs.@Html.DisplayFor(Model => Model.First().PurchasedOrderTotalAmount)</td>
         </tr>
        </tbody>
      </table>
     </div>
</div>
