What is the command in C  for exit a Console Application

User · Answer

Console applications will exit when the main function has finished running. A "return" will achieve this.

    static void Main(string[] args)
    {
        while (true)
        {
            Console.WriteLine("I'm running!");
            return; //This will exit the console application's running thread
        }
    }

If you're returning an error code you can do it this way, which is accessible from functions outside of the initial thread:

    System.Environment.Exit(-1);

You can use Environment Exit 0  and Application Exit   Environment Exit    terminates this process and gives the underlying operating system the specified exit code

Several options  by order of most appropriate way    Return an int from the Program Main method Throw an exception and don t handle it anywhere  use for unexpected error situations  To force termination elsewhere  System Environment Exit  not portable  see below    Edited 9 2013 to improve readability  Returning with a specific exit code  As Servy points out in the comments  you can declare Main with an int return type and return an error code that way  So there really is no need to use Environment Exit unless you need to terminate with an exit code and can t possibly do it in the Main method  Most probably you can avoid that by throwing an exception  and returning an error code in Main if any unhandled exception propagates there  If the application is multi-threaded you ll probably need even more boilerplate to properly terminate with an exit code so you may be better off just calling Environment Exit   Another point against using Evironment Exit - even when writing multi-threaded applications - is reusability  If you ever want to reuse your code in an environment that makes Environment Exit irrelevant  such as a library that may be used in a web server   the code will not be portable  The best solution still is  in my opinion  to always use exceptions and or return values that represent that the method reached some error finish state  That way  you can always use the same code in any  NET environment  and in any type of application  If you are writing specifically an app that needs to return an exit code or to terminate in a way similar to what Environment Exit does  you can then go ahead and wrap the thread at the highest level and handle the errors exceptions as needed
