C# process.start, how do I know if the process ended?

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 */ }; 

Answer 2

Process p = new Process(); p.Exited += new EventHandler(p_Exited); p.StartInfo.FileName = @"path to file"; p.EnableRaisingEvents = true; p.Start();  void p_Exited(object sender, EventArgs e) {     MessageBox.Show("Process exited"); }
