To complete the process, use Environment.Exit .

    You need to throw an exception, like:

    throw new Exception("Пипец всему!");

    Or just

     void Main(){ //твой код if (error) return; }

      The thrown exception is accepted to be caught and processed. And during processing, the same problem arises - how to shut down the program. That's why I say - the exception has nothing to do with it, the program is closed with no exception. - Pavel Mayorov
