Question

In C#, I can start a process with

process.start(program.exe);

How do I tell if the program is still running, or if it closed?

Answer 1

MSDN System.Diagnostics.Process

If you want to know right now, you can check the HasExited property.

var isRunning = !process.HasExited;

If it’s a quick process, just wait for it.

process.WaitForExit();

If you’re starting one up in the background, subscribe to the Exited event after setting EnableRaisingEvents to true.

process.EnableRaisingEvents = true;
process.Exited += (sender, e) => {  /* do whatever */ };
