获取indexoutorange异常

得到一个异常消息"There is no row at position 1"

如果我们在datatgridview中输入2行或更多，并单击save按钮，它只插入第一行，并给出一个异常。

下面是代码片段:

private void btnSave_Click(object sender, EventArgs e)
{    
   for (int i = 0; i < dataGridView1.Rows.Count; i++)
   {
         table = obj.select("select id from stock where item_name='" + dataGridView1.Rows[i].Cells[0].FormattedValue + "'");
          obj.query("insert into poi_items (po_id, stock_id, description, expected_price, discount, quantity, expected_total, status, received)values(" + textBox3.Text + "," + table.Rows[i][0] + ",'" + dataGridView1.Rows[i].Cells[1].FormattedValue + "'," + dataGridView1.Rows[i].Cells[3].FormattedValue + "," + dataGridView1.Rows[i].Cells[5].FormattedValue + "," + dataGridView1.Rows[i].Cells[2].FormattedValue + "," + dataGridView1.Rows[i].Cells[6].FormattedValue + ",'Open','0')");                    
   }
 }

table.Rows[i]
