Timer in C#

This tutorial will discuss the methods for creating a timer in C#.

Create a Timer With the Timer Class in C#

The Timer class is used to create an event after a set time interval in C#. We can generate an event that repeats itself after a specified amount of time with the Timer class in C#. The Timer.Elapsed event is used to specify the event to be repeated. The following code example shows us how to create a timer that repeats an event after a specified interval of time with the Timer class in C#.

using System;
using System.Timers;

namespace timer {
  class Program {
    private static void OnTimedEvent(object source, ElapsedEventArgs e) {
      Console.WriteLine("Hello World!");
    }
    static void Main(string[] args) {
      System.Timers.Timer myTimer = new System.Timers.Timer();
      myTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
      myTimer.Interval = 500;
      myTimer.Enabled = true;

      Console.WriteLine("Press \'e\' to escape the sample.");
      while (Console.Read() != 'e')
        ;
    }
  }
}

Output:

Press 'e' to escape the sample.
Hello World!
e

In the above code, we created a timer that repeats the output Hello World! after every 500 milliseconds until the character e is entered in C#. We first initialized the instance myTimer of the Timer class. Then we specified the OnTimedEvent() function to be the event for the Time.Elapsed event. The interval is set to be 500 milliseconds with the myTimer.Interval property. In the end, we started the timer with the myTimer.Enabled property.
