一:NuGet中搜索包:Microsoft.Win32.TaskScheduler并引用:

        public static void RunTaskService(string vbsRootPath)        {            string taskName = "HelperTray1";            TaskService ts = new TaskService();            Microsoft.Win32.TaskScheduler.Task wsTask = ts.GetTask(taskName);            if (wsTask == null)            {                string vbsStart = Path.Combine(vbsRootPath, "Start.vbs");//ApiConfig.ExtPath                TaskDefinition td = ts.NewTask();                td.RegistrationInfo.Description = taskName;                //开机后2分钟开始运行任务                //td.Triggers.Add(new BootTrigger { Delay = new TimeSpan(0, 2, 0) });                //参数1 Interval 间隔:每次重新启动任务之间的时间量。允许的最长时间为31天,允许的最短时间为1分钟                //参数2 Duration 持续时间:重复模式的持续时间。允许的最短时间是一分钟。如果指定了TimeSpan.Zero,则该模式将无限期地重复。                //参数3:获取或设置一个布尔值,该值指示正在运行的任务实例在重复模式持续时间结束时停止。                RepetitionPattern repetition = new RepetitionPattern(new TimeSpan(0, 1, 0), TimeSpan.Zero, true);                td.Triggers.Add(new DailyTrigger { Repetition = repetition });                td.Actions.Add(new ExecAction("wscript.exe", vbsStart, null));                ts.RootFolder.RegisterTaskDefinition(taskName, td);            }        }

二、在系统C:\Windows\System32 下查找DLL:taskschd.dll并引用到项目中:

        public static void CreateTaskScheduler(string vbsRootPath)        {            try            {                LogEvent.LogInfo.Fatal("2创建计划任务:1");                string taskName = "HelperTray2";                TaskSchedulerClass scheduler = new TaskSchedulerClass();                //pc-name/ip,username,domain,password                scheduler.Connect(null, null, null, null);                ITaskFolder folder = scheduler.GetFolder("\\");                IRegisteredTask rt = null;                try                {                    //搜索不到会抛异常                    rt = folder.GetTask(taskName);                    if (rt != null)                        return;                }                catch(Exception ex)                {                    LogEvent.LogInfo.Info("任务计划程序不存在,创建:");                }                                LogEvent.LogInfo.Fatal("2创建计划任务:2");                //set base attr                 ITaskDefinition task = scheduler.NewTask(0);                //task.RegistrationInfo.Author = "system";//creator                 task.RegistrationInfo.Description = taskName;                //set trigger  (IDailyTrigger ITimeTrigger)　设置小时/分/秒来实现                //  ITimeTrigger tt = (ITimeTrigger)task.Triggers.Create(_TASK_TRIGGER_TYPE2.TASK_TRIGGER_TIME);                //  tt.Repetition.Interval = interval;// format PT1H1M==1小时1分钟 设置的值最终都会转成分钟加入到触发器                //设置每天特定的时间来实现                 IDailyTrigger tt = (IDailyTrigger)task.Triggers.Create(_TASK_TRIGGER_TYPE2.TASK_TRIGGER_DAILY);                tt.StartBoundary = string.Format("1970-05-01T{0}:00:00", "04");                tt.EndBoundary = string.Format("2100-05-01T{0}:00:00", "04");                //tt.Repetition= new RepetitionPattern                //start time //set action                IExecAction action = (IExecAction)task.Actions.Create(_TASK_ACTION_TYPE.TASK_ACTION_EXEC);                action.Path = "wscript.exe";                string vbsStart = Path.Combine(vbsRootPath, "HelperStart.vbs");//ApiConfig.ExtPath                action.Arguments = vbsStart;//运行程序时需要的参数,如果没有可以不写。                task.Settings.ExecutionTimeLimit = "PT0S"; //运行任务时间超时停止任务吗? PTOS 不开启超时                 task.Settings.DisallowStartIfOnBatteries = false;//只有在交流电源下才执行                 task.Settings.RunOnlyIfIdle = false;//仅当计算机空闲下才执行                 IRegisteredTask regTask = folder.RegisterTaskDefinition(taskName, task, (int)_TASK_CREATION.TASK_CREATE, null, null, _TASK_LOGON_TYPE.TASK_LOGON_INTERACTIVE_TOKEN, "");                IRunningTask runTask = regTask.Run(null);                //return runTask.State;                LogEvent.LogInfo.Fatal("2创建计划任务:3");            }            catch (Exception ex)            {                LogEvent.LogInfo.Fatal("创建计划任务异常:"+ex);                //throw ex;             }        }
