.NET定时任务执行管理器开源组件–FluentScheduler，可以在web应用程序里面使用

 public class MvcApplication : System.Web.HttpApplication

            RegisterRoutes(RouteTable.Routes);

            //创建任务
            try
            {                
                string timeSet = System.Configuration.ConfigurationManager.AppSettings["RunTime"];//获取配置文件任务执行设置时间
                DateTime setRunTime = Convert.ToDateTime(timeSet);
                Registry task = new Registry();
                task.Schedule(() => Run_ServerUpload()).ToRunEvery(1).Days().At(setRunTime.Hour, setRunTime.Minute);//任务每天定时执行
                FluentScheduler.JobManager.Initialize(task);
                //启动服务日志
                LogManager.AddLog("700", "启动服务成功", "UplodLog");
                LogManager.AddLine("UplodLog", 1);
            }

                LogManager.AddLine("UplodLog", 1);
            }
        }
        /// <summary>

            LogManager.AddLog("300", "设置的执行时间" + timeSet, "UplodLog");
            LogManager.AddLog("300", "======开始自动执行上传方法", "UplodLog");
            WebApplicationBAOJI.Controllers.HomeController hc = new Controllers.HomeController();
            string dateSeach = DB.GetLiJiDate().ToString("yyyy-MM-dd");

            LogManager.AddLog("300", "自动执行上传完成", "UplodLog");
        }

        protected void Application_End(object sender, EventArgs e)
        {
            try
            {
                LogManager.AddLog("4", "进程即将被IIS回收", "Application_End");
                LogManager.AddLog("4", "重新访问一个页面，以唤醒服务", "Application_End");
                string strUrl = System.Configuration.ConfigurationManager.AppSettings["SelfAddress"];//本程序部署地址
                System.Net.HttpWebRequest httpWebRequest = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(strUrl);
                System.Net.HttpWebResponse httpWebResponse = (System.Net.HttpWebResponse)httpWebRequest.GetResponse();
                System.IO.Stream stream = httpWebResponse.GetResponseStream();//得到回写的字节流
                httpWebResponse.Close();
            }
            catch (Exception ex)
            {
                LogManager.AddLog("4", "唤醒服务异常：" + ex.Message, "Application_End");
            }
        }

该服务会被IIS回收，所以要在Application_End结束程序时，要自己访问自己，保证不会被iis回收掉，这样才能保证24小时不间断服务，才不会中断，切记
