FormClosing顯示兩次退出確認消息框

Question

我在關閉表單時遇到問題。 它顯示2次我的退出確認消息框，並詢問2次“確定要退出嗎？”：

if (MessageBox.Show("Are you sure to exit. Confirm?", "Rest O Rant", MessageBoxButtons.YesNo) == DialogResult.Yes)
{
    Application.Exit();
    MessageBox.Show("Thank You For Using Rest O Rant Software.", "Closing message!", MessageBoxButtons.OK);
}
else
{
    e.Cancel = true;
    this.Activate();
}   

Answer 1

試試這個代碼

MessageBox.Show("Thank You For Using Rest O Rant Software.", "Closing message!", MessageBoxButtons.OK);

Application.Exit();
