Question

I have a console application that runs on my computer. When the application throws an exception, I want to restart the application. How can I accomplish this?

Answer 1

You can instantiate a Timer that check every n seconds if the process is alive, for example you can write i function like the following to verify if the process is alive :

 public static bool ProcessExist(string processname)
        {
            Process[] aProc = Process.GetProcessesByName(processname);
            return (aProc.Length > 0);
        }

Every Tick of the timer you can check if the process is alive or not, if not you can relaunch it.

Another method could be use a ManagementEventWatcher for get fired an event every time that a process stop on your machine, so for example :

ManagementEventWatcher stopWatchProcess = new ManagementEventWatcher(new WqlEventQuery("SELECT * FROM Win32_ProcessStopTrace"));
                stopWatchProcess.EventArrived += new EventArrivedEventHandler(stopWatchProcess_EventArrived);
                stopWatchProcess.Start();


private void stopWatchProcess_EventArrived(object sender, EventArrivedEventArgs e) {
            string processName = (string)e.NewEvent.Properties["ProcessName"].Value;
            if(processName == "yourprocess.exe") {
              //Do Something
     }
        }
