您好我想为列表中的每个项目执行总计。我为每个项目计算了一个值calculateValue =(价格x数量)。但是现在我想把那个calculateValue添加到overallTotal并在底部显示这个变量。
我的错误是,如果我有例如totalTotal = 50.00 + 10.00 + 20.00
当我显示@overallTotal时,它将显示为“50.0010.0020.00”而不是80.00。我无法转换为int,否则我将丢失小数点
这是我的表格的代码
<tbody>
<tr>
<th><i class="icon_pin_alt"></i> Item Description</th>
<th><i class="icon_pin_alt"></i> Quantity</th>
<th><i class="icon_calendar"></i> Price</th>
<th></th>
</tr>
@foreach (var item in Model.ITEM_ORDER)
{
decimal computedValue = item.item_order_quantity * item.ITEM.item_price;
decimal overallTotal = 0;
overallTotal= 0+(overallTotal+ computedValue);
<tr style="background-color:white; border-style:hidden">
<td style="width:auto">
@Html.DisplayFor(modelItem => item.ITEM.item_brand)
@Html.DisplayFor(modelItem => item.ITEM.item_description)
</td>
<td style="width:auto">
@Html.DisplayFor(modelItem => item.item_order_quantity)
</td>
<td style="width:auto">
R @computedValue
</td>
<td>
<div class="btn-group; background-color:white">
@Html.ActionLink("View", "Details", new { id = item.OrderID }) |
@Html.ActionLink("Edit", "Edit", new { id = item.OrderID }) |
@Html.ActionLink("Delete", "Delete", new { id = item.OrderID })
</div>
</td>
</tr>
<tr>R @overallTotal</tr>
}
</tbody>
</table>
答案 0 :(得分:0)
阅读完ASP文档后,我意识到你需要用&#39; m&#39;字符将它们视为小数,如果不是它们是双打。这应该有效:
// Before the loop
@{ decimal overallTotal = 0M; }
// for...
decimal computedValue = (decimal) item.item_order_quantity * (decimal) item.ITEM.item_price;
overallTotal += computedValue;
// end for
如果 item.item_order_quantity 已经是小数,请删除转换。对于 item.ITEM.item_price 。
也是如此
