(c#) how to detect the monitor status

Question

0.00/5 (No votes)

See more:

I have a console application.
Import a Dll to get the monitor status.
such as the monitor is off or monitor is on.
i use the "protected override void WndProc(ref System.Windows.Forms.Message m)"
mothod in the dll project,
of course i have to use the "WndProc" method under a winForm.
So when my program is running, it will display a winForm and a console window.
it seem to no useful when the focus is not on the winForm.
i think that the "WndProc"is invalid when the focus is not on the winForm.
How can i get the monitor status in the Dll?
any help will be appreciated.

thank you for your help.
but i think this problem's key is the program how to "know" monitor off or on.
for example the system's setting is the monitor's power will shut down after 5 mins.i need to run the program to monitoring it.when the monitor is power off. the program can "know" it.
