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.com") ? 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());        }
