windows - Checking for workstation lock/unlock change with c#

Question

DUPLICATE: How can I programmatically determine if my workstation is locked?

How can I detect (during runtime) when a Windows user has locked their screen (Windows+L) and unlocked it again. I know I could globally track keyboard input, but is it possible to check such thing with environment variables?

Answer 1

A SessionSwitch event may be your best bet for this. Check the SessionSwitchReason passed through the SessionSwitchEventArgs to find out what kind of switch it is and react appropriately.
