这是我的代码:
private void btnReminder_Click(object sender, EventArgs e)
{
timer2.Start();
}
private void timer2_Tick(object sender, EventArgs e)
{
DateTime Date = DateTimePickerReminderDate.Value;
DateTime Time = DateTimePickerReminderTime.Value;
if (DateTime.Now.CompareTo(Date) > 0 && DateTime.Now.CompareTo(Time) > 0)
{
Date = DateTime.MaxValue;
Time = DateTime.MaxValue;
MessageBox.Show("Your Reminder");
timer2.Stop();
}
}
当我设置提醒时,它按预期工作并在正确的时间显示消息。但问题是,它不断弹出消息框我试图清除此错误但我没有成功。所以现在我需要专家建议所以请帮我清除这个错误。

MessageBox
会在显示时阻止您的UI线程,在您单击对话框之前,您将无法访问timer.Stop()
。
尝试停止计时器,然后显示MessageBox
:
private void timer2_Tick(object sender, EventArgs e)
{
DateTime Date = DateTimePickerReminderDate.Value;
DateTime Time = DateTimePickerReminderTime.Value;
if (DateTime.Now.CompareTo(Date) > 0 && DateTime.Now.CompareTo(Time) > 0)
{
timer2.Stop();
Date = DateTime.MaxValue;
Time = DateTime.MaxValue;
MessageBox.Show("Your Reminder");
}
}
