How can I support Screen brightness with C#

[Steve]

I have a project, and would like to support screen brightness up/down in C#,
anyone can help me about this issue, I know one possibility is write a
driver, and
AP through driver to control the H/W.

Is anyway can adjust the screen brightness without driver?

Steve,

If the display supports it, you can call the DeviceIoControl function
through the P/Invoke layer in the Windows API, and pass
IOCTL_VIDEO_SET_DISPLAY_BRIGHTNESS for the dwControlCode parameter.

Hope this helps.

Nicholas,

thanks for the hint, yes, it should be the easiest way to adjust the
brightness, really appreciated.
