我是 ASP.NET MVC 新手，我的问题是，我想添加页脚以显示列的总和。
Controller
List<GenerateTicket_Details> bk = new List<GenerateTicket_Details>();
con.Open();
string query = "";
query += @" select TicketNo,Name,ArrDate,sum(CostumeQuantity) As Quantity, sum(CostumeTotalPrice) As Total, sum(ISNULL(RefundAmount,0)) AS REFUND
,sum(ISNULL(CostumeTotalPrice,0) - ISNULL(RefundAmount,0)) AS TotalAmount from GenerateTicket where 1=1";
query += @" Group by TicketNo,Name,ArrDate ";
SqlCommand cmd = new SqlCommand(query, con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
cmd.CommandType = CommandType.Text;
DataSet ds = new DataSet();
da.Fill(ds);
foreach (DataRow dr in ds.Tables[0].Rows)
{
bk.Add(new GenerateTicket_Details() { TicketNo = dr[0].ToString(), name = dr[1].ToString(), ArrDate = dr[2].ToString(), quantity = dr[3].ToString(), Total = Convert.ToDecimal(dr[4].ToString()), Refund = Convert.ToDecimal(dr[5].ToString()), TotalAmount = Convert.ToDecimal(dr[6].ToString()) });
string orderDetails = dr[3].ToString();
}
cmd.ExecuteNonQuery();
ViewBag.MyCustomCollection = bk;
return View(bk);
查看
<tbody>
@foreach (var item in Model)
{
<tr>
<td style="padding-left: 12px;">@Html.DisplayFor(modelItem => item.TicketNo)</td>
<td style="padding-left: 12px; display: none;">@Html.DisplayFor(modelItem => item.name)</td>
<td style="padding-left: 12px;">@Html.DisplayFor(modelItem => item.ArrDate)</td>
<td style="padding-left: 12px;">@Html.DisplayFor(modelItem => item.quantity)</td>
<td style="padding-left: 12px;">@Html.DisplayFor(modelItem => item.Total)</td>
<td>@Html.DisplayFor(modelItem => item.Refund)</td>
<td>@Html.DisplayFor(modelItem => item.TotalAmount)</td>
</tr>
}
</tbody>
我想在列表的最后显示 TotalAmount 的总和
最佳答案
C# 代码:
ViewBag.TotalAmount = ds.Tables[0].Select().Sum(w=> (int) w["RefundAmount"] );
- ds 是您的数据集对象
- (int) w["RefundAmount"] 使用您的类型和属性
html:
<tbody>
@foreach (var item in Model)
{
.......
}
<tr><td>TotalAmount : @ViewBag.TotalAmount</td></tr>
</tbody>
希望对你有帮助:)
