Wait for process to finish and then display message (C#)

Question

I would like to be able to watch a process until it is terminated, and once non existent display a message, how could this be achieved?

Answer 1

Create/Attach to the process and then either use WaitForExit() to block until it has exited, or use the OnExited Event if you don't wish your application to block while it's waiting for the app to exit.

I heartily recommend reviewing the documentation for Process - right here

Answer 2

The .NET Framework has built in support for this. You need to use the Process.Start method to start the process, and then call the WaitForExit method, which will block execution of your application until the process you started has finished and closed.

Sample code:

// Start the process.
Process proc = Process.Start("notepad.exe");  // TODO: NEVER hard-code strings!!!

// Wait for the process to end.
proc.WaitForExit();

// Show your message box.
MessageBox.Show("Process finished.");

I think this is what you want to do:

System.Diagnostics.Process process=new System.Diagnostics.Process();
process.StartInfo.FileName = "process.exe";
process.Start();
process.WaitForExit();
//process ended
MessageBox.Show("Process terminated");
