C# 定時調用方法

private void button1_Click(object sender, EventArgs e)
        {
            System.Timers.Timer timer = new System.Timers.Timer();
            timer.Enabled = true;
            timer.Interval = 4000;//4秒執行間隔時間,單位為毫秒    
            timer.Start();
            timer.Elapsed += new System.Timers.ElapsedEventHandler(Timer1_Elapsed);
            // timer.Stop();停止

}

　　調用得方法：

 private void Timer1_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
        {
 
            // 得到intHour,intMinute,intSecond，是當前系統時間    
            int intHour = e.SignalTime.Hour;
            int intMinute = e.SignalTime.Minute;
            int intSecond = e.SignalTime.Second;
            // System.Windows.Forms.MessageBox.Show(intSecond.ToString());
            //自己設置hour,minuter,second,到設定的時間就開始執行程序    
            //if (intHour == hour && intMinute == minutes && intSecond == second)
            //{
            //    //System.Windows.Forms.MessageBox.Show("時間到了！");                        
            //}
           
        }
