Timer Constructor ()
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.
Imports System.Timers Public Module Example Private aTimer As Timer Public Sub 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. AddHandler aTimer.Elapsed, AddressOf 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() End Sub Private Sub OnTimedEvent(source As Object, e As System.Timers.ElapsedEventArgs) Console.WriteLine("The Elapsed event was raised at {0}", e.SignalTime) End Sub End Module ' 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
