How do I use a timer in C#?

You can use the System.Timers.Timer class to create a timer in C#. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

using System;
using System.Timers;

class Program
{
    private static Timer aTimer;

    static void Main()
    {
        aTimer = new Timer(2000); // Set the timer interval to 2 seconds
        aTimer.Elapsed += OnTimedEvent;
        aTimer.AutoReset = true;
        aTimer.Enabled = true;

        Console.WriteLine("Press [Enter] to exit...");
        Console.ReadLine();
    }

    private static void OnTimedEvent(Object source, ElapsedEventArgs e)
    {
        Console.WriteLine("The Elapsed event was raised at {0:HH:mm:ss.fff}", e.SignalTime);
    }
}

This code sets up a timer that triggers every 2 seconds.

What if I want the timer to run only once?

You can set aTimer.AutoReset to false. This way, the timer will only trigger once.
