MVC 定时执行任务

环境:.net4.5

需求:需要一个方法定时执行任务

解决: System.Threading.Timer 提供以指定的时间间隔执行方法的机制。 此类不能被继承,有10多种实例化方法,满足多种情况.

步骤:委托方法,注册执行

1.代码主体

 public class CensusdemoTask
    {
        System.Threading.Timer timer;
        private static int count = 1;

        public CensusdemoTask()
        {
            timer = new System.Threading.Timer(SetCensusURL, null, 0, 1000 * 60);
        }
        [MethodImpl(MethodImplOptions.Synchronized)]
        public void SetCensusURL(object obj)
        { 
            string txt = string.Format("写入时间:{0},次数{1}", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"), count);
            FileInfo f = new FileInfo("/124.txt");
            StreamWriter sw = File.Exists("/124.txt") ? f.CreateText() : f.AppendText();
            byte[] txtbytes = Encoding.UTF8.GetBytes(txt);
            sw.WriteLine(txt);
            sw.Flush();
            sw.Close();
            count++;
        }
    }

2.注册 Global.asax.cs

 protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
           //注册,
            BLL.SystemTask.CensusUrlTask t = new BLL.SystemTask.CensusUrlTask();
           
           WebApiConfig.Register(GlobalConfiguration.Configuration);
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
          
           // DependencyResolver.SetResolver(new NinjectDependencyResolver());
            //ControllerBuilder.Current.SetControllerFactory(new NinjectDependencyResolver());
        }
