using System;
using System.Timers;

class Program
{
    static void Main(string[] args)
    {
        Timer timer = new Timer(5000); // Set timer for 5 seconds
        timer.Elapsed += (sender, e) => ExecuteFunction(timer);
        timer.AutoReset = false; // Ensure it only runs once
        timer.Start();

        Console.WriteLine("Timer started. Waiting for 5 seconds...");
        Console.ReadLine(); // Keep the application running
    }

    static void ExecuteFunction(Timer timer) {
        timer.Stop();
        Console.WriteLine("Function executed after 5 seconds!");
    }
