C# 如何在gridview中求和从asp.net数据库中选择数据

我在asp.net中工作，我有一个网格视图，其中我从基本工资中找出pf和ESI值，我希望在Repues的gridview页脚中找到总pf和总ESI之和的正确解决方案，因此请帮助我

您必须在gridview的RowDataBound事件中编写代码

我发布了一个示例代码供您参考，您自己试试吧

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
   if (e.Row.RowType == DataControlRowType.DataRow)
   {
      Label lblPrice = (Label)e.Row.FindControl("lblPrice");
      Label lblUnitsInStock = (Label)e.Row.FindControl("lblUnitsInStock");

      decimal price = Decimal.Parse(lblPrice.Text);
      decimal stock = Decimal.Parse(lblUnitsInStock.Text);

      totalPrice += price;
      totalStock += stock;

      totalItems += 1;
   }

   if (e.Row.RowType == DataControlRowType.Footer)
   {
      Label lblTotalPrice = (Label)e.Row.FindControl("lblTotalPrice");
      Label lblTotalUnitsInStock = (Label)e.Row.FindControl("lblTotalUnitsInStock");

      lblTotalPrice.Text = totalPrice.ToString();
      lblTotalUnitsInStock.Text = totalStock.ToString();

      lblAveragePrice.Text = (totalPrice / totalItems).ToString("F");
   }
}
