如何在ASP.NET的网格视图中计算总价

decimal totalPrice = 0;

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        // 获取当前行的数据字段的值
        decimal price = Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "Price"));

        // 累加总价
        totalPrice += price;
    }
    else if (e.Row.RowType == DataControlRowType.Footer)
    {
        // 在页脚行显示总价
        Label lblTotalPrice = (Label)e.Row.FindControl("lblTotalPrice");
        lblTotalPrice.Text = totalPrice.ToString("C"); // 格式化为货币格式
    }
}
