是否可以显示最多5次的消息框？

Question

我希望我的while循环使用一个消息框最多提问5次。

当我运行它时，我会问一次，当我选择是时，会打开5个新表格。

如何解决此循环问题，以防止消息框询问用户是或不超过5次，以及如何选择一次，则防止打开5个表单？

我的代码

 private void btnNext_Click(object sender, EventArgs e)
    {
        int maxAddDriver = 5;
        int addDriver = 0;

        DialogResult answer = MessageBox.Show("Would you like to add an additional driver to policy?", "Info", MessageBoxButtons.YesNo, MessageBoxIcon.Information);

        Hide();

        while (addDriver < maxAddDriver && answer == DialogResult.Yes)
        {
            addDriver++;

            Hide();

            new frmAdditionalDriver().Show();


            //answer = MessageBox.Show("Would you like to add an additional driver to policy?",
            //    "Info", MessageBoxButtons.YesNo, MessageBoxIcon.Information);
        }


        new frmInsurancePolicy().ShowDialog();

        Show();
    }

请尝试以下操作：将maxAddDriver和addDriver移到按钮单击之外，这样就不会在每次单击按钮时重置它们，并保留以前的单击计数。

int maxAddDriver = 5;
int addDriver = 0;

private void btnNext_Click(object sender, EventArgs e)
{
    answer = MessageBox.Show("Would you like to add an additional driver to policy?", "Info", MessageBoxButtons.YesNo, MessageBoxIcon.Information);

    addDriver++;

    Hide();  


        //answer = MessageBox.Show("Would you like to add an additional driver to policy?",
        //    "Info", MessageBoxButtons.YesNo, MessageBoxIcon.Information);


    if (addDriver == maxAddDriver && answer == DialogResult.Yes)
    {
        new frmAdditionalDriver().Show();
    }
    else if (addDriver == maxAddDriver || answer == DialogResult.No)
    {
        new frmInsurancePolicy().ShowDialog();
    }

    Show();
}
