Why? What have you tried so far?
One more advice: don't do anything urgently; this is a sure way to make bad things, such as the one you want to do now.

Solution 1

Here: "User Idle Detection"[^] a sample imlpementation using the Windows API function GetLastInputInfo. I don't know if the Framework provides an equivalent functionality.

The idea is not bad, even though the inquirer probably did not mean that. But overall, even this would the evil. Only the user knows exactly when to close something. But I voted 5 because there could be some rare reasons, such as security. But even then it will create more of illusion of safety than real safety. Please see also my answer.

Solution 2

You can find the idle time through GetLastInputInfo function
and then you can write you own logic to close the form or what you want.

Here is good article with the complete solution
Getting the user idle time with C#[^]

Hope, it helps :)

The only ideal time for closing a form is the time when a user explicitly closes it by a mouse click or a keyboard.

If you think you know exact time better and has nothing else to do, you can use:
https://msdn.microsoft.com/en-us/library/system.windows.forms.form.close%28v=vs.110%29.aspx[^],
https://msdn.microsoft.com/en-us/library/system.windows.forms.timer%28v=vs.110%29.aspx[^] (this is one of the very rare cases when one can use this timer type, which is good almost for nothing).

But better don't do evil.
