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.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()); }
