最好安排在C＃中的任务的方式 [英] Best way to schedule tasks in C#

问题描述

我正在开发，需要能够调度各种异步任务在不同的时间C＃程序。我需要一个解决方案，激活每一秒钟检查任务的执行，并吃掉了尽可能少的资源成为可能。这也需要很好地扩展到了大量的任务。哪一项是更好地使用，或者是有什么？

I'm developing a C# program that needs to be able to schedule a variety of asynchronous tasks at different times. I need a solution that activates every second to check for tasks to execute, and eats up as few resources as possible. It also needs to scale well to a large number of tasks. Which of these is better to use, or is there any ?

1）使用与1秒的总时间System.Timers.Timer的目的在于，触发执行任务的事件，或者

1) Using a System.Timers.Timer object with a 1 second elapsed time to trigger an event that executes tasks, or

2）使用休眠1秒一个单独的线程，然后执行任务时就醒来，或

2) Using a separate thread that sleeps for 1 second and then executes tasks when it wakes up, or

3）完全是另一回事。

3) Something else entirely.

推荐答案

System.Threading.Timer 是极其轻便。你可以为每个任务一个单独的计时器，这样计时器来，由于任务的时候应该执行。

System.Threading.Timer is extremely lightweight. You could create a separate timer for each task so that the timer comes due when the task is supposed to execute.

在内部，我认为，该系统会跟踪哪些定时器是由于旁边，因此只需要监控一个定时器，在任何给定时间（<一href="http://stackoverflow.com/questions/31581/how-scalable-is-system-threading-timer">source/similar问题）。

Internally, I believe that the system will keep track of what timer is due next so it only has to monitor one timer at any given time (source/similar question).
