how press enter button automatically after 5 seconds in c#?

Hello @Priyanka   you  can use this code

 static void Main(string[] args)
        {
            System.Timers.Timer aTimer = new System.Timers.Timer();
            aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
            aTimer.Interval = 5000;
            aTimer.Enabled = true;

            Console.WriteLine("Press \'q\' to quit the sample.");
            while (Console.Read() != 'q') ;
           

        Console.ReadLine();

        }

         private static void OnTimedEvent(object source, ElapsedEventArgs e)
         {
             Console.WriteLine("Hello World!");

             // Here you can write your Code
         }
