C# 虽然调用了命令，但TaskScheduler未创建任务

我有一个WiX安装程序，其中我有以下自定义操作来在任务调度器中创建两个任务

[CustomAction]
        public static ActionResult CreateScheduleTaskForUpdateTriggering(Session session)
        {
            session.Log("Creating the Scheduled Task");
            string MyAppPath = Environment.GetEnvironmentVariable("MyAppPATH");
            if (!IsTaskExisting("MyAppUpdateTrigger"))
            {
                session.Log("Command Created : " + "C:\\Windows\\System32\\SCHTASKS.exe /Create /TN \"MyAppUpdateTrigger\" /SC ONCE /TR \"" + Path.Combine(new string[] { MyAppPath, "Watchdog", "RunMyAppInstaller.bat" }) + "\" /RL HIGHEST");
                Process p = Process.Start("C:\\Windows\\System32\\SCHTASKS.exe", " /Create /TN \"MyAppUpdateTrigger\" /SC ONCE /TR \"" + Path.Combine(new string[] { MyAppPath, "Watchdog", "RunMyAppInstaller.bat" }) + "\" /ST 00:00:00 /SD 01/01/1990 /RL HIGHEST");
            }
            else
            {
                session.Log("MyAppUpdateTrigger schedule already exists");
            }
            return ActionResult.Success;
        }

        [CustomAction]
        public static ActionResult CreateScheduleTaskForRunningWatchdog(Session session)
        {
            session.Log("Creating the Scheduled Task for running watch dog");

            string MyAppPath = Environment.GetEnvironmentVariable("MyAppPATH");

            if (!IsTaskExisting("RunWatchDog"))
            {
                session.Log("Command Created : " + "C:\\Windows\\System32\\SCHTASKS.exe /Create /TN \"RunWatchDog\" /SC ONSTART /TR \"" + Path.Combine(new string[] { MyAppPath, "Watchdog", "RunWatchDog.bat" }) + "\" /RL HIGHEST");
                Process p = Process.Start("C:\\Windows\\System32\\SCHTASKS.exe", " /Create /TN \"RunWatchDog\" /SC ONSTART /TR \"" + Path.Combine(new string[] { MyAppPath, "Watchdog", "RunWatchDog.bat" }) + "\" /ST 00:00:00 /SD 01/01/1990 /RL HIGHEST");
            }
            return ActionResult.Success;
        }

我正在调用这些，如下所示，在我的WiX文件中

<CustomAction Id="CA_scheduleTaskAction" BinaryKey="removeFolderCustomActionDLL" DllEntry="CreateScheduleTaskForUpdateTriggering" Execute="commit" Return="ignore" />
<CustomAction Id="CA_scheduleTaskActionForWatchDog" BinaryKey="removeFolderCustomActionDLL" DllEntry="CreateScheduleTaskForRunningWatchdog" Execute="commit" Return="ignore" />

<InstallExecuteSequence>
  <!--Custom Action="LaunchWatchdog" After="InstallFinalize" /-->
  <Custom Action="WatchDog.TaskKill" Before="InstallValidate"/>
  <Custom Action="CA_scheduleTaskAction" After="InstallFiles"/>
  <Custom Action="CA_scheduleTaskAction" After="InstallFiles"/>
  <Custom Action="CA_myCustomAction" Before="InstallFinalize">Installed</Custom>
</InstallExecuteSequence>

现在，我明白了。从文件：

/SC时间表

指定计划频率的值。有效值为：分钟、小时、每日、每周、每月、一次、ONLOGON、ONIDLE和ONEVENT

您是否尝试过更可靠的编程方式。我打印了错误代码。这就是我得到的。“-2147467259”有什么想法吗（这是一个运行时错误，原因可能会有所不同。很难说。解决了这个问题。这与“启动”命令有关。当我说“一次”时，它可以正常工作。有什么想法吗？哦！我如何通过命令行发出此onstart命令？因为任务调度器计划的其他方法需要一些代码更改：（也在这里，他们说这是可以做到的不？此外，当我通过命令行手动运行此命令时，它会起作用！对，文档有点混乱。我现在正在遍历它。试试这个，将您的示例与您的进行比较。
