从火中的OnStart窗口服务立即timer_elapsed [英] Fire timer_elapsed immediately from OnStart in windows service

问题描述

我使用的是 System.Timers.Timer 和我有一样在我的的OnStart 方法在C＃中的窗口服务

I'm using a System.Timers.Timer and I've got code like the following in my OnStart method in a c# windows service.

timer = new Timer();
timer.Elapsed += timer_Elapsed;
timer.Enabled = true;
timer.Interval = 3600000;
timer.Start();

这会导致 timer_Elapsed 中的代码是执行的每一个小时一个小时后，开始我启动该服务。有没有办法让在我启动该服务，然后每隔一小时以后它的点执行？

This causes the code in timer_Elapsed to be executed every hour starting from an hour after I start the service. Is there any way to get it to execute at the point at which I start the service and then every hour subsequently?

按 timer_Elapsed 调用的方法需要很长时间才能运行，直接从的OnStart叫它。

The method called by timer_Elapsed takes too long to run to call it directly from OnStart.

推荐答案

刚开始一个线程池线程调用函数的工人一样，定时器一样。像这样的：

Just start a threadpool thread to call the worker function, just like Timer does. Like this:

        timer.Elapsed += timer_Elapsed;
        ThreadPool.QueueUserWorkItem((_) => DoWork());
    ...

    void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e) {
        DoWork();
    }

    void DoWork() {
        // etc...
    }
