Timer Constructor ()
.NET Framework (current version)
Initializes a new instance of the Timer class, and sets all the properties to their initial values.
Assembly: System (in System.dll)
The following table shows initial property values for an instance of Timer.
Property | Initial value |
|---|---|
true | |
false | |
100 milliseconds | |
A null reference (Nothing in Visual Basic). |
The following example instantiates a Timer object that fires its Timer.Elapsed event every two seconds (2000 milliseconds), sets up an event handler for the event, and starts the timer. The event handler displays the value of the ElapsedEventArgs.SignalTime property each time it is raised.
using System; using System.Timers; public class Example { private static Timer aTimer; public static void Main() { // Create a timer and set a two second interval. aTimer = new System.Timers.Timer(); aTimer.Interval = 2000; // Hook up the Elapsed event for the timer. aTimer.Elapsed += OnTimedEvent; // Have the timer fire repeated events (true is the default) aTimer.AutoReset = true; // Start the timer aTimer.Enabled = true; Console.WriteLine("Press the Enter key to exit the program at any time... "); Console.ReadLine(); } private static void OnTimedEvent(Object source, System.Timers.ElapsedEventArgs e) { Console.WriteLine("The Elapsed event was raised at {0}", e.SignalTime); } } // The example displays output like the following: // Press the Enter key to exit the program at any time... // The Elapsed event was raised at 5/20/2015 8:48:58 PM // The Elapsed event was raised at 5/20/2015 8:49:00 PM // The Elapsed event was raised at 5/20/2015 8:49:02 PM // The Elapsed event was raised at 5/20/2015 8:49:04 PM // The Elapsed event was raised at 5/20/2015 8:49:06 PM
