asp.net C#中timer类的用法

public class BF_CheckUpdate
      {
          private static object LockObject = new Object();
 
          // 定义数据检查Timer
          private static Timer CheckUpdatetimer = new Timer();
 
          // 检查更新锁
          private static int CheckUpDateLock = 0;
 
          ///
 /// 设定数据检查Timer参数
 ///
          internal static void GetTimerStart()
          {
              // 循环间隔时间(10分钟)
              CheckUpdatetimer.Interval = 600000;
              // 允许Timer执行
              CheckUpdatetimer.Enabled = true;
              // 定义回调
              CheckUpdatetimer.Elapsed += new ElapsedEventHandler(CheckUpdatetimer_Elapsed);
              // 定义多次循环
              CheckUpdatetimer.AutoReset = true;
          }
 
          ///
 /// timer事件
 ///
 ///
 ///
          private static void CheckUpdatetimer_Elapsed(object sender, ElapsedEventArgs e)
          {
             // 加锁检查更新锁
              lock (LockObject)
              {
                  if (CheckUpDateLock == 0) CheckUpDateLock = 1;
                  else return;
              }        
           
             //More code goes here.
 //具体实现功能的方法
             Check();
                // 解锁更新检查锁
              lock (LockObject)
              {
                  CheckUpDateLock = 0;
              }           
          }
  }
