c# - 获取gridview单元格的总和不包括最后一个单元格

Question

我正在尝试获取单元格的总和以找到订单总数。这是我的代码

  protected void OrdelistDetails_RowDataBound(object sender, GridViewRowEventArgs e)
    {

        if (e.Row.RowType == DataControlRowType.DataRow)
        {

            decimal sum = 0;

            for (int i = 0; i < OrdelistDetails.Rows.Count; ++i)
            {

                sum += Convert.ToDecimal((OrdelistDetails.Rows[i].FindControl("lblitemTotal") as Label).Text);

            }

            lblTotal.Text =  sum.ToString();



        }

它工作正常，但它不添加最后一个单元格

Answer 1

尝试使用小于或等于；<= 而不是 <

 for (int i = 0; i <= OrdelistDetails.Rows.Count; ++i)
            {

                sum += Convert.ToDecimal((OrdelistDetails.Rows[i].FindControl("lblitemTotal") as Label).Text);

            }
