将值赋给datagridview的特定单元格

Question

我有一个datagridview视图，其数量和价格的倍数值应显示在dgview.的数量列中，我将粘贴到目前为止尝试过的代码。但是它会在以下行中抛出错误

 dgvpricelist.Rows[i].Cells["totalamount"].Value = totalprice;

抛出的错误是"Stack overflow exception error"。不知道为什么会抛出错误

 public void totalcalculation()
    {

        if (dgvpricelist.Rows.Count > 1)
        {
            double TAmount = 0;

            for (int i = 0; i < dgvpricelist.Rows.Count; i++)
            {
                int quantity = Convert.ToInt32(dgvpricelist.Rows[i].Cells["quantity"].Value);
                double itemPrice = Convert.ToDouble(dgvpricelist.Rows[i].Cells["intpricelvl1"].Value);

                totalprice = quantity * itemPrice;
                dgvpricelist.Rows[i].Cells["totalamount"].Value = totalprice;

                edittotalprice = Convert.ToDouble(dgvpricelist.Rows[i].Cells["totalamount"].Value);
                TAmount += edittotalprice;
                //txtboxtaxvalue.Text = tax.ToString();
                //txtboxtotalvalue.Text = total.ToString();
                //TAmount = edittotalprice;
            }

            int roundedtotal = (int)Math.Round(TAmount);
            txtboxstotalvalue.Text = TAmount.ToString();
            txtboxtotalvalue.Text = roundedtotal.ToString();
        }

我可以知道实现目标的正确方法是什么？
