将datagrid值传递给mysql命令参数

Question

我正在尝试将数据网格中的行添加到mysql数据库中。我的问题是传递数据网格值

dt.Rows[i - 1][1] = dtgPo.Rows[i - 1].Cells["poCode"].Value.ToString(); 

到

cmd = new MySqlCommand("INSERT INTO poitems (poid,, poCode, itemCode, itemName) VALUES (?id,?pocode,?itemcode,?itemname)", coninsert); 

希望你能帮帮我们。谢谢你们！

private void button3_Click(object sender, EventArgs e)
    {
        char pocode;
        char itemcode;
        char itemname;
        int i;

        MySqlDataAdapter da = new MySqlDataAdapter("SELECT * FROM poitems", coninsert);
        MySqlCommandBuilder cb = new MySqlCommandBuilder(da);
        DataTable dt = new DataTable();
        da.Fill(dt);            


        for (i = 1; i < dtgPo.RowCount; i++)
        {
            MySqlDataAdapter da2 = new MySqlDataAdapter();
            MySqlCommand cmd;
            MySqlParameter parm;
            // Create the SelectCommand.

            dt.Rows[i - 1][1] = dtgPo.Rows[i - 1].Cells["poCode"].Value.ToString();
            dt.Rows[i - 1][2] = dtgPo.Rows[i - 1].Cells["itemCode"].Value.ToString();
            dt.Rows[i - 1][3] = dtgPo.Rows[i - 1].Cells["itemName"].Value.ToString();

            cmd = new MySqlCommand("SELECT * FROM poitems", coninsert);

            // Create the InsertCommand.
            cmd = new MySqlCommand("INSERT INTO poitems (poid,, poCode, itemCode, itemName) VALUES (?id,?pocode,?itemcode,?itemname)", coninsert);
            cmd.Parameters.Add("?id", MySqlDbType.Int16, 11, "poid");
            cmd.Parameters.Add("?pocode", MySqlDbType.Int16, 11, "poCode");
            cmd.Parameters.Add("?itemcode", MySqlDbType.Int16, 11, "itemCode");
            cmd.Parameters.Add("?itemname", MySqlDbType.VarChar, 40, "poCode");

            da2.InsertCommand = cmd;
            //return da;
        }


    }
