.NET，每分钟（在分钟）事件。是一个定时器的最佳选择？ [英] .NET, event every minute (on the minute). Is a timer the best option?

问题描述

我想用C＃做的东西在分钟每分钟（由时钟）的Windows窗体应用程序。我只是想知道最新最好的路要走呢？

I want to do stuff every minute on the minute (by the clock) in a windows forms app using c#. I'm just wondering whats the best way to go about it ?

我可以用一个定时器和间隔设置为60000，但要获得它的运行分钟，我将不得不启用它的微小precisely，没有真正可行的。

I could use a timer and set its interval to 60000, but to get it to run on the minute, I would have to enable it on the minute precisely, not really viable.

我可以用一个定时器和间隔时间设置为1000。那么它的Tick事件中，我可以检查时钟当前分钟对我设置一个变量，如果微小改变，然后运行我的code。这令我很担心，因为我让我的电脑做一次检查，以便开展工作，每隔1分钟，每1秒。当然，这是丑陋的？

I could use a timer and set its interval to 1000. Then within its tick event, I could check the clocks current minute against a variable that I set, if the minute has changed then run my code. This worries me because I am making my computer do a check every 1 second in order to carry out work every 1 minutes. Surely this is ugly ?

我使用的是Windows窗体和NET 2.0所以不希望使用自带的.Net 3.5 DispatchTimer

I'm using windows forms and .Net 2.0 so do not want to use the DispatchTimer that comes with .Net 3.5

这必须是一个相当普遍的问题。有任你一个更好的方式来做到这一点？

This must be a fairly common problem. Have any of you a better way to do this?

推荐答案

大厦答案从阿奎那可以漂移，这不正是对刚分钟内分一秒滴答：

Building on the answer from aquinas which can drift and which doesn't tick exactly on the minute just within one second of the minute:

static System.Timers.Timer t;

static void Main(string[] args)
{
    t = new System.Timers.Timer();
    t.AutoReset = false;
    t.Elapsed += new System.Timers.ElapsedEventHandler(t_Elapsed);
    t.Interval = GetInterval();
    t.Start();
    Console.ReadLine();
}

static double GetInterval()
{
    DateTime now = DateTime.Now;
    return ((60 - now.Second) * 1000 - now.Millisecond);
}

static void t_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
    Console.WriteLine(DateTime.Now.ToString("o"));
    t.Interval = GetInterval();
    t.Start();
}

在我的盒子此code一贯蜱每分钟.02s内：

On my box this code ticks consistently within .02s of each minute:

2010-01-15T16:42:00.0040001-05:00
2010-01-15T16:43:00.0014318-05:00
2010-01-15T16:44:00.0128643-05:00
2010-01-15T16:45:00.0132961-05:00
