VB.NET 2010 如何在类Class1中调用timer事件 触发 的方法

Public Class Class1
    Private WithEvents MyTimer As New Timer
    Private intSum As Integer

    Public Sub New(ByVal intInterval As Integer)
        MyTimer.Interval = intInterval       'intInterval设置为1000 就是间隔1秒
        MyTimer.Enabled = True             '启动Timer
    End Sub

    Private Sub MyTimer_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyTimer.Tick
        '***********在此处加上你要操作的代码************Start
        intSum = intSum + 1      '如累加intSum的值
        '***********在此处加上你要操作的代码************End
    End Sub
