How do I determine if a process is associated with a System.Diagnostics.Process object?

Question

Given a particular System.Diagnostics.Process that has been assigned values to its properties .FileName and .Arguments, what is the best way to determine if it:

1. has ever been issued a .Start() command or
2. is currently associated with a process at all?

If .Start() was never issued, then calling .CloseMainWindow() causes an InvalidOperationException, which I'd like to avoid.

Answer 1

Have you tried checking Process.Id and one of the Exit properties ?

Ref.

In response to poster's comments: perhaps you will have to wrap in a try/catch and an exception being thrown indicates not started? It's not pretty!

Answer 2

You could try and check

process.StartTime & process.HasExited
process.Handle

or perhaps use

process.WaitForExit
