//传参数定时器

private static System.Timers.Timer aTimer;

 Main(ApprovalID);

public static void Main(int ApprovalID)
        {
            aTimer = new System.Timers.Timer(600000); //10分钟 600000
            aTimer.Elapsed += new ElapsedEventHandler((s, e) => OnTimedEvent(s, e, ApprovalID));
            aTimer.Interval = 60000;
            aTimer.Enabled = true;
            aTimer.AutoReset = false;
        }

        private static void OnTimedEvent(object source, ElapsedEventArgs e, int ApprovalID)
        {
            
            //解锁申请表
            Model.Sys.ShenPiApprovalModel SQM = new ShenPiApprovalModel();
            SQM = BLL.Sys.ShenPiApprovalBLL.Instance.GetModel(ApprovalID);
            if (SQM.ApprovalState != 1)
            {
                SQM.ApprovalState = 0;//锁定申请表
                BLL.Sys.ShenPiApprovalBLL.Instance.UpdateJS(0, " ");
            }
            
        }

二、

//不传参数 定时器

             System.Timers.Timer t = new System.Timers.Timer(60000);//实例化Timer类，设置间隔时间为10000毫秒；
                t.Elapsed += new System.Timers.ElapsedEventHandler(theout);//到达时间的时候执行事件；
                t.AutoReset = false;//设置是执行一次（false）还是一直执行(true)；
                t.Enabled = true;//是否执行System.Timers.Timer.Elapsed事件；

       //定时器函数
        public void theout(object source, System.Timers.ElapsedEventArgs e)
        {
            Model.User.UserModel userM = new Model.User.UserModel();
            var MM = BLL.User.UserBLL.Instance.GetModel(6326);
            MM.LinkMan = "定时器我是";
            BLL.User.UserBLL.Instance.Update(MM);
        }
