从Datagridview和Access [论文制作]中删除行

Question

所以，我试图删除一行，但它一直出现

我的代码是

private void btnDelete_Click(object sender, EventArgs e)
    {
        if (dtgAccs.Rows.Count > 1)
        {
            if (dtgAccs.CurrentRow.Index == dtgAccs.Rows.Count - 1)
            {
                MessageBox.Show("Please re-select rows.");
            }
            else
            {
                if (DialogResult.Yes == MessageBox.Show(("Delete Account?"), "Message", MessageBoxButtons.YesNo))
                {
                    dtgAccs.Rows.RemoveAt(dtgAccs.CurrentRow.Index);
                    db.execSQL("DELETE from Accounts WHERE ID='" + IDa + "'AND Full_Name ='" + FullN + "'AND Email ='"
                        + Emaila + "'AND User_name ='" + Usernamea + "'AND Pass_word ='" + Passworda + "'AND Position_a ='" + Positiona + "'" );
                    MessageBox.Show("Account has been deleted.");
                }
            }
        }
        else
        {
            MessageBox.Show("No Account to delete.");
        }
    }

我现在得到了答案。感谢我的导师帮助我做什么做XD

 if (DialogResult.Yes == MessageBox.Show(("Delete Account?"), "Message", MessageBoxButtons.YesNo))
                {
                    int userId = Convert.ToInt32(dtgAccs.Rows[dtgAccs.CurrentRow.Index].Cells[0].Value);
                    Console.Write(userId);


                    db.execSQL("DELETE from Accounts WHERE ID=" + userId);


                    dtgAccs.Rows.RemoveAt(dtgAccs.CurrentRow.Index);

                    MessageBox.Show("Account has been deleted.");
                }

你只需要制作一个变量并转换它:)希望这对其他人也有帮助
