C#定时器和事件

System.Timers.Timer myTimer;
private void Form1_Load(object sender, EventArgs e)
{
           myTimer = new System.Timers.Timer(60000);//定时周期1分钟
            myTimer.Elapsed += myTimer_Elapsed;//到1分钟了做的事件
            myTimer.AutoReset = true; //是否不断重复定时器操作  
｝
 //定时器执行事件
        void myTimer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
        {
            GetUser(lblUserID.Text.Trim(), lblConnection.Text.Trim());
            GetDepart(lblUserDepart.Text.Trim(), lblConnection.Text.Trim());
        }
