ASP.NET中Timer的运用

在Global.asax中

private static readonly ILog log = LogManager.GetLogger(typeof(Global));
        Timer logTimer = null;
        protected void Application_Start(object sender, EventArgs e)
        {
            
            XmlConfigurator.Configure();
            logTimer = new Timer(new TimerCallback(Log), null, 0, 1000);
        }
        protected void Application_End(object sender, EventArgs e)
        {
            if (logTimer != null)
            {
                logTimer.Dispose();
            }
        }
        private void Log(object obj)
        {
            log.Debug("this programe is running!");
        }
