C # application process startup and shutdown

Sometimes there is a need, a process that only starts one, and must start one.

You can create a Windows service that executes at timed intervals. The number of application processes is queried each time it executes, if not, one is started, and if more than one is started, only one is left

Nonsense not much to say, on the code:

1   Public classClass12     {3         Public voidMain ()4        {5            varObj=system.diagnostics.process.getprocessesbyname ("Calc"). ToList ();6            if(obj. Count = =0)7 startprocess ();8            Else if(obj. Count = =1)9Systemlog.writelogline ("only one process starts, no action required");Ten            Else One killprocess (); A startprocess (); -        } -  the         Public voidstartprocess () -        { -ProcessStartInfo info =NewProcessStartInfo (); -Info. FileName =@"D:\Calc.exe"; +Info. Arguments =""; -Info. WindowStyle =processwindowstyle.minimized; +Process Pro =Process.Start (info); A            //Pro.  WaitForExit ();  at        } -         Public voidkillprocess () -        { -Process current =process.getcurrentprocess (); -Process[] processes = Process.getprocessesbyname ("Calc"); -            foreach(Process processinchprocesses) in            { -                if(Process. ProcessName = ="Calc") to process. Kill (); +            }    -        } the}
