using System.Timers; // use this to do the Timers or you can replace the Timer with System.Timers.Timer

namespace CA_TimerProject

        public static Timer ExplanationTimer = new Timer(); // Create a new timer 

        static void Main(string[] args)
        {
            Console.Title = "C# Explain Timers"; // Console Title
            
            
            ExplanationTimer.Elapsed += new ElapsedEventHandler(ExplanationTimer_Elapsed); // Create a new void that does something when the timer ends
            ExplanationTimer.Interval = 300000; // 1000 ticks * 60 seconds * 5 minutes | tells when the timer stops and then restarts (ofcourse you can make it completely stop forever)
            ExplanationTimer.Start(); // starts the timer
    
            Console.ReadLine();
        }

        static void ExplanationTimer_Elapsed(object sender, ElapsedEventArgs e) // Once again this action happens once the timer reaches the interval of 5 minutes
        {
            Console.WriteLine("5 Minutes has passed");
            ExplanationTimer.Stop(); // stops the timer so it does not repeat itself (I am sure this is what you want)
        }
    }
