I was put in a situation where the abrupt batch end will still have to be handled. More precisely, after the user presses Ctrl+C to stop the batch, the program would have to save a log and then exit gracefully.

So, without further ado:

1. Declare a boolean flag:
   private bool canceled = false;
2. Subscribe to the CancelKeyPress event:
   Console.CancelKeyPress += new ConsoleCancelEventHandler(Console_CancelKeyPress);
3. In the event handler, set the flag and cancel the CancelKeyPress event:
   private void Console_CancelKeyPress(object sender, ConsoleCancelEventArgs e)
   {
       canceled =true;
       Console.WriteLine(“\r\nCtrl-C was pressed, process interrupted by user”);
       e.Cancel =true;
   }
4. In your for loop, which could be a conversion, migration, build, report &c, first check the exit condition: If met, exit gracefully:
   if (canceled)
   {
       EndLogging();
       break;
   }
