这是更好地用于经常性工作：服务或计划任务？ [英] Which is better to use for a recurring job: Service or Scheduled Task?
问题描述
我有一个需要每30秒运行任务。我可以做两件事情之一：
I have a task that needs to run every 30 seconds. I can do one of two things:
-
编写，一旦运行任务，等待30秒的命令行应用程序，运行它再次，然后退出。我可以在Windows中使用计划任务安排此任务运行每分钟
Write a command line app that runs the task once, waits 30 seconds, runs it again and then exits. I can schedule this task with Scheduled Tasks in Windows to run every minute
编写重复运行任务，而在每次运行之间等待30秒的服务。
Write a Service that runs a task repeatedly while waiting 30 seconds in between each run.
1号更是微不足道，在我看来，我会选择在默认情况下做这种方式。我是不是wimping了呢？是否有一个原因，我应该使这一服务，而不是计划的任务？什么是两者的利弊，这将你到底挑
Number 1 is more trivial, in my opinion and I would opt to do it this way by default. Am I wimping out? Is there a reason why I should make this a Service and not a scheduled task? What are the pros and cons of both and which would you pick in the end?
推荐答案
的I读一篇好的博客贴子这个问题最近。它进入了很多很好的原因，你应该的不的写一个服务运行循环作业。
I read a nice blog post about this question recently. It goes into a lot of good reasons why you should not write a service to run a recurring job. Additionally, this question has been asked before:

利用所调度的任务的一个优点是，如果有涉及运行的服务的一些潜在风险如内存泄漏，或挂网络连接，那么Windows服务可能会挂aroung很长一段时间，造成负面影响其他用户。另一方面，预定任务写入短的运行，所以，即使它的泄漏，效果被最小化。
One advantage of using the scheduled task, is that if there is some potential risk involved with running the service such as a memory leak or hanging network connection, then the windows service can potentially hang aroung for a long time, adversely affecting other users. On the other hand, the scheduled task is written to be short running, so even if it does leak, the effect is minimised.
在另一方面，有人在一个上述问题评论说，调度有1分钟的范围内某处精度的限制，所以你可能会看到，调度程序无法运行，每30秒准确你的任务。
On the other hand, someone in one of the above questions commented that the scheduler has a limit of accuracy of somewhere in the range of 1 minute, so you may see that the scheduler is unable to run your task every 30 seconds with accuracy.
显然有一些折衷的考虑，但希望这会帮助你做出一个好的决定。
Obviously there are a number of tradeoffs to consider, but hopefully this will help you make a good decision.
