C# 定时调用方法

private void button1_Click(object sender, EventArgs e)
        {
            System.Timers.Timer timer = new System.Timers.Timer();
            timer.Enabled = true;
            timer.Interval = 4000;//4秒执行间隔时间,单位为毫秒    
            timer.Start();
            timer.Elapsed += new System.Timers.ElapsedEventHandler(Timer1_Elapsed);
            // timer.Stop();停止

}

　　调用得方法：

 private void Timer1_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
        {
 
            // 得到intHour,intMinute,intSecond，是当前系统时间    
            int intHour = e.SignalTime.Hour;
            int intMinute = e.SignalTime.Minute;
            int intSecond = e.SignalTime.Second;
            // System.Windows.Forms.MessageBox.Show(intSecond.ToString());
            //自己设置hour,minuter,second,到设定的时间就开始执行程序    
            //if (intHour == hour && intMinute == minutes && intSecond == second)
            //{
            //    //System.Windows.Forms.MessageBox.Show("时间到了！");                        
            //}
           
        }
