Time limit when entering choice

Known Issues

• The player can repeatedly enter other choices to prevent the time from running out, this could be stopped by removing the else in have turn and placing the code within it later.

Extra declarations and namespacing

using System.Timers;//Add the Timer class to allow checking how much real time has passed
        

        private static Timer T = new Timer(5000);//Create a new instance of the class Timer with a 5 second delay between event calls
        private static bool Timeout = false;//A variable to check whether time has run out

GetChoice

private static string GetChoice()
        {
            Timeout = false; //This ensures that each time a player enters a choice they have the right amount of time.
            
            // . . .
            
            T.Start();//This starts counting real time using an event.
            T.Elapsed += T_Elapsed;//This subscribes the event to a delegate, it allows a method to run after a set amount of time
            
            // . . .
            
            //The following if clears the choice to make it tidier
            if (Timeout)
            {
                Choice = "";
            }

            // . . .
        }

New Method

        //This method is auto generated upon entering T.Elapsed += then pressing tab
        //It is a method that is called whenever T.Elapsed is called. (This is a event that is subscribed to the delegate T.Elapsed)
        static void T_Elapsed(object sender, ElapsedEventArgs e)
        {
            Console.WriteLine("Your time has run out. Press enter to continue");
            Timeout = true;//Once time has run out the program needs to know for future use
            T.Stop();//The delegate should not keep running, otherwise the time player 2 gets is less then player 1.
            T.Elapsed -= T_Elapsed;//If the event doesn't unsubscribe then it will begin stacking, each time it runs the message will appear an extra time
            
        }

HaveTurn

        private static void HaveTurn(/*.Nothing changes in here.*/)
        {
            // . . .
            while (!ValidChoice)
            {
                Choice = GetChoice();
                if (Timeout)//This sends the player to the end of their turn, if they ran out of time.
                {
                    return;
                }
                else//If they didn't run out of time then they have reached this the time can be prepared for next time.
                {
                    T.Stop();
                    T.Elapsed -= T_Elapsed;
                }
            // . . .
            }
