ASP.NET MVC 启动定时任务删除某一文件夹下面的全部文件

1.通过程序包管理器控制台来安装Quartz.Net组件:Install-Package Quartz

2.新建一个类命名为 ReportJob: IJob

using Quartz;

using System.IO;

public void Execute(IJobExecutionContext context)

        {

            var reportDirectory = string.Format("~/ZIP/");

            reportDirectory = System.Web.Hosting.HostingEnvironment.MapPath(reportDirectory);

            //获取文件夹中所有文件

            if (Directory.GetFileSystemEntries(reportDirectory).Length > 0)

            {

                //遍历文件夹中所有文件

                foreach (string file in Directory.GetFiles(reportDirectory))

                {

                    //文件己存在

                    if (File.Exists(file))

                    {

                        FileInfo fi = new FileInfo(file);

                        //判断当前文件属性是否是只读

                        if (fi.Attributes.ToString().IndexOf("ReadyOnly") >= 0)

                        {

                            fi.Attributes = FileAttributes.Normal;

                        }

                        //删除文件

                        File.Delete(file);

                    }

                }

                //删除文件夹

          //      Directory.Delete(reportDirectory);

            }

         //   throw new NotImplementedException();

        }

3.新建一个类命名为 ReportJobScheduler

using Quartz;

using Quartz.Impl;

  public static void Start()

        {

            IScheduler scheduler = StdSchedulerFactory.GetDefaultScheduler();

            scheduler.Start();

            IJobDetail job = JobBuilder.Create<ReportJob>().Build();

            ITrigger trigger = TriggerBuilder.Create()

              .WithIdentity("triggerName", "groupName")

              .WithSimpleSchedule(t =>

                t.WithIntervalInSeconds(5) //设置多少秒执行一次

                 .RepeatForever())

                 .Build();

            scheduler.ScheduleJob(job, trigger);

        }

4.在 Gloabl.asax 启动方法中添加启动任务

  protected void Application_Start()

        {

            AreaRegistration.RegisterAllAreas();

            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);

            RouteConfig.RegisterRoutes(RouteTable.Routes);

            BundleConfig.RegisterBundles(BundleTable.Bundles);

            //启动定时任务

            ReportJobScheduler.Start();

        }
