How Can I Create a Precise and Reliable Timer in C#?

Building a High-Precision, Reliable Timer in C#

For creating a highly accurate and dependable timer in C#, the System.Timers.Timer class provides a robust solution. This class allows you to schedule tasks at specific intervals.

The Interval property of the Timer object sets the time between timer events. Setting this to 15000 milliseconds (15 seconds) triggers the associated method every 15 seconds.

Below is a code example showcasing the Timer class:

using System;
using System.Timers;

public class TimerExample
{
    public static void Main(string[] args)
    {
        // Create a timer with a 15-second interval
        Timer timer = new Timer(15000); 
        timer.Elapsed += OnTimedEvent; // Attach the event handler
        timer.Start(); // Start the timer

        Console.WriteLine("Press 'q' to exit.");
        while (Console.ReadKey().Key != ConsoleKey.Q) { } // Keep the console app running
    }

    // Method executed when the timer elapses
    private static void OnTimedEvent(object sender, ElapsedEventArgs e)
    {
        Console.WriteLine("Timer event triggered.");
    }
}

This code creates a timer that calls the OnTimedEvent method every 15 seconds. The Console.ReadKey() method keeps the console application running until the user presses 'q'.
