问题是在循环中又做了一步，因为datagradview自己添加一行

代码将是

for (int i = 0; i < (dataGridView2.Rows.Count)-1; i++)
            {
                StrQuery = "insert into branch1_orders values("
                    + order_num + ","
                    + dataGridView2.Rows[i].Cells["number"].Value + ","
                    + dataGridView2.Rows[i].Cells["price"].Value + ")";
                command.CommandText = StrQuery;
                command.ExecuteNonQuery();

                try
                {
                    command.ExecuteNonQuery();
                }
                catch (MySql.Data.MySqlClient.MySqlException e2)
                {
                    MessageBox.Show(e2.Message);
                }
            }
