推荐答案

您将需要计时器来测量空闲时间，并需要某种跟踪机制来跟踪用户的交互与形式.如果经过了空闲时间，则必须用MessageBox等通知用户.
在这种情况下，我将使用System.Timers.Timer类.

You''ll need timer to measure idle time and some kind of tracking mechanism to keep track of user''s interaction with form. If idle time elapses then you''ll have to inform user with MessageBox etc.
In this case I would use System.Timers.Timer class.

private void someTextBox_TextChanged(object sender, EvetArgs e)
{
    //do some work
    ResetIdleTimer();
}

private void someCheckBox_ChekChanged(object sender, EvetArgs e)
{
    //do some work
    ResetIdleTimer();
}

//.....
//etc. you got the picture
//.....

private void ResetIdleTimer()
{
   idleTimer.Stop();
   idleTimer.Start();
}


void idleTimer_Elapsed(object sender, ElapsedEventArgs e)
{
    MessageBox.Show("Whatever you want to say to user");
    //your logging off code  and closing code go here
    //this.Close();
}

引入 System.Windows.Fomrs.Timer [ ^ ].设置其时间间隔 [标记 [
现在，您必须捕获每个可能的用户操作.每次与用户互动时，首先停止 [ ^ ]计时器，然后开始 [

Incorporate a System.Windows.Fomrs.Timer[^]. Set its Interval[^] property to five minutes. Subscribe a method to its Tick[^] event. In that method, disable your Form and show the "You''ve been logged out..." message.

Now you have to catch each and every possible user intaraction. With every user interaction, first Stop[^] the timer, then Start[^] it again. AFAIR that will cause the timer to wait for Interval again. If not, set the interval before calling Start.
