Get unique ID for a running process
I'm currently looking to replace a system I've previously implemented that generates a unique id that is valid from when the process opens until when it closes, a random unique ID is generated using a mix of system time and other variables each time the application is started.
What I'm looking to do is generate a unique identifier for the process itself, the Process ID isn't something I can use as it's possible that it's reused
Does anyone know of a way to generate a unique id for a single process based on the process itself?

Could you use a guid? That would most likely be unique.

Yes, it would, what I need though is something that I can continually generate within the same session that has the same ID, simply based on the Process.

What about using combining the process PID with the number of ticks picked from datetime.Now ? Or total seconds from epoch, depending of your process creation rate ?

How these IDs are used?

@DanHall Why? This looks like an XY problem.

Process.StartTime.Ticks can be used an unique identifier because its impossible to run more than a process in a single tick

if we are talking about possibilities then add process id asa a prefix to that uniuq identifier string :)
