private void btn_insert_item_Click(object sender, EventArgs e)
        {
            if(textBox9.Text != "" & textBox10.Text != "" & textBox11.Text != "")
            {
                DialogResult dialog = MessageBox.Show("Do you want to add item #" + textBox11.Text + "?",
                    "", MessageBoxButtons.YesNo);
                if (dialog == DialogResult.Yes)
                {
                    try
                    {
                        con.Open();
                        OracleCommand cmd = new OracleCommand("insert " +
                        "into table_a " +
                        "(order_date, " +

                        )", con);
                        cmd.CommandType = CommandType.Text;
                        OracleDataReader dr = cmd.ExecuteReader();
                        System.Data.DataTable dt = new System.Data.DataTable();
                        dt.Load(dr);
                        dataGridView1.DataSource = dt;
                        dr.Close();
                    }

                    catch (Exception ex)
                    {
                        MessageBox.Show(ex.Message);
                    }

                    finally
                    {
                        con.Close();
                        MessageBox.Show("item has been added.");
                    }
                }

                if (dialog == DialogResult.No)
                {
                    MessageBox.Show("No change has been made.");
                    button1_Click(sender, e);
                }
            }
    }

这是我用于在table_a上插入单个项目＃的代码。 textBox 9 = order_date，textBox10 = order_no，textBox11 = item_no。如果我也有item_no的textBox12，那么如何在dataGridView上插入带有item_no的多行？如果我将item_no 1放在textBox11上，将10放在textBox12上，它应该插入10行，这些行具有相同的信息，但item_no从1到10。

请帮助。

Answer 1

尝试使用textBox12.text作为计数器创建循环

例如：

for(int x=1;x<textBox12.text;x++)
{
  //Your code.....
}

如何在C＃上的datagridview中插入多行？
