示例1: Example
' 導入命名空間
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輸出：
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
