I am looking for a way to trigger a piece of code when a console application is manually closed  users closes window   Been trying with   AppDomain CurrentDomain ProcessExit        new EventHandler CurrentDomain ProcessExit     but the above doesn t work if manually closed   Is there any ways to use a  Net call for this or do I need to import the Kernel dll and do it that way

You need to hook to console exit event and not your process   http   geekswithblogs net mrnat archive 2004 09 23 11594 aspx  Capture console exit C

This code works to catch the user closing the console window   using System  using System Runtime InteropServices   class Program       static void Main string   args            handler   new ConsoleEventDelegate ConsoleEventCallback           SetConsoleCtrlHandler handler  true           Console ReadLine               static bool ConsoleEventCallback int eventType            if  eventType    2                Console WriteLine  Console window closing  death imminent                      return false            static ConsoleEventDelegate handler       Keeps it from getting garbage collected        Pinvoke     private delegate bool ConsoleEventDelegate int eventType        DllImport  kernel32 dll   SetLastError   true       private static extern bool SetConsoleCtrlHandler ConsoleEventDelegate callback  bool add        Beware of the restrictions   You have to respond quickly to this notification  you ve got 5 seconds to complete the task   Take longer and Windows will kill your code unceremoniously   And your method is called asynchronously on a worker thread  the state of the program is entirely unpredictable so locking is likely to be required   Do make absolutely sure that an abort cannot cause trouble   For example  when saving state into a file  do make sure you save to a temporary file first and use File Replace
