Is there any available function or method to Restart the application on the C console#?

static void decision()
    {
        Console.WriteLine("\n Press the home key to recalculate. . .", Console.ForegroundColor = ConsoleColor.Blue);
        Console.ResetColor();

        Console.WriteLine(" Press the esc key to exit. . .", Console.ForegroundColor = ConsoleColor.Magenta);
        Console.ResetColor();

        var option = Console.ReadKey();

        if (option.Key == ConsoleKey.Escape)
        {
            Environment.Exit(0);
        }
        else if (option.Key == ConsoleKey.Home)
        {
            /* reiniciar aplicação console aqui */
        }
        else
        {
            Console.Clear();
            Console.WriteLine("\n Invalid option, try again!", Console.ForegroundColor = ConsoleColor.Red);
            Console.ResetColor();
            decision();
        }
    }

  • What is restarting the application? Better say what you need instead of trying to do something random, you probably don’t need what you’re asking.

Can be restarted by finishing the current process and creating a new.

As you did not specify which Framework is used, I took the liberty of exemplifying in . NET Core

 class Program
    {
        static bool flag;

        static void Main(string[] args)
        {
            Console.CancelKeyPress += Console_CancelKeyPress;
            while (!flag)
            {
                Console.WriteLine("\n Press the home key to recalculate. . .", Console.ForegroundColor = ConsoleColor.Blue);
                Console.ResetColor();

                Console.WriteLine(" Press the esc key to exit. . .", Console.ForegroundColor = ConsoleColor.Magenta);
                Console.ResetColor();

                var option = Console.ReadKey();

                if (option.Key == ConsoleKey.Escape)
                {
                    flag = true;
                }
                else if (option.Key == ConsoleKey.Home)
                {
                    Process.Start("cmd", $"/c dotnet {Assembly.GetExecutingAssembly().Location}");
                    flag = true;

                }
                else
                {
                    Console.Clear();
                    Console.WriteLine("\n Invalid option, try again!", Console.ForegroundColor = ConsoleColor.Red);
                    Console.ResetColor();
                }
            }

        }

        private static void Console_CancelKeyPress(object sender, ConsoleCancelEventArgs e)
        {
            Environment.Exit(0);
        }
    }

The event Console_CancelKeyPress is triggered only when the Ctrl+C keys are pressed.

There are some alternatives to get the result you want. The first I can think of is to create a method on the side and call it again

    class Program
    {
        static void Main(string[] args)
        {
            run();
        }
        static void run()
        {
            Console.WriteLine("\n Press the home key to recalculate. . .", Console.ForegroundColor = ConsoleColor.Blue);
            Console.ResetColor();

            Console.WriteLine(" Press the esc key to exit. . .", Console.ForegroundColor = ConsoleColor.Magenta);
            Console.ResetColor();

            var option = Console.ReadKey();

            if (option.Key == ConsoleKey.Escape)
            {
                Environment.Exit(0);
            }
            else if (option.Key == ConsoleKey.Home)
            {
                run();
            }
            else
            {
                Console.Clear();
                Console.WriteLine("\n Invalid option, try again!", Console.ForegroundColor = ConsoleColor.Red);
                Console.ResetColor();

            }
        }
    }

The other would simply put inside a while loop

    class Program
    {
        static void Main(string[] args)
        {
            while (true)
            {

                Console.WriteLine("\n Press the home key to recalculate. . .", Console.ForegroundColor = ConsoleColor.Blue);
                Console.ResetColor();

                Console.WriteLine(" Press the esc key to exit. . .", Console.ForegroundColor = ConsoleColor.Magenta);
                Console.ResetColor();

                var option = Console.ReadKey();

                if (option.Key == ConsoleKey.Escape)
                {
                    break;
                }
                else if (option.Key == ConsoleKey.Home)
                {
                    continue;
                }
                else
                {
                    Console.Clear();
                    Console.WriteLine("\n Invalid option, try again!", Console.ForegroundColor = ConsoleColor.Red);
                    Console.ResetColor();

                }
            }
            Environment.Exit(0);
        }
    }
