Pass cmd argument to running process when shutting down windows service

Question

I am creating a windowservice that starts a process where I pass multiple cmd arguments in the StartInfo.Arguments. That works fine as expected.

The problem is that when i stop the windowsservice, I need to tell the running program to shut down gracefully before the windows service stops. Because if I just kill the process the program does not save the collected data. The program that I run is the Process Monitor and it accepts the following command "/terminate".

How can I pass the /terminate argument before my windows service stops?

Answer 1

I managed to find a solution. In the OnStop() method in the service, I needed to create a new instance of the Process Monitor and pass the /Terminate argument:

Process process = new Process();
process.FileName = "\Procmon.exe" ;
process.StartInfo.Arguments = "/AcceptEula /Terminate";
process.Start();

With that it stoppes all the Process Monitor instances gracefully.
