Kill child process when parent process is killed

Question

I\'m creating new processes using System.Diagnostics.Process class from my application.

I want this processes to be killed when/if my application has cr

Answer 1

I had the same problem. I was creating child processes that never got killed if my main app crashed. I had to destroy manually child processes when debugging. I found that there was no need to make the children somewhat depend on parent. In my main, I added a try catch to do a CleanUp() of child processes on exit.

    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        try
        {
            Application.Run(new frmMonitorSensors());
        }
        catch(Exception ex)
        {
            CleanUp();
            ErrorLogging.Add(ex.ToString());
        }
    }

    static private void CleanUp()
    {
        List processesToKill = new List() { "Process1", "Process2" };
        foreach (string toKill in processesToKill)
        {
            Process[] processes = Process.GetProcessesByName(toKill);
            foreach (Process p in processes)
            {
                p.Kill();
            }
        }
    }
