What is the equivalent of a timer tick of 30 minutes?
提问by geoNeo_
I have a timer tick that I would like to kick off my backgroundworker every 30 minutes. What is the equivalent value of 30 minutes for a timer tick?
我有一个计时器滴答声，我想每 30 分钟启动一次我的后台工作人员。计时器滴答的 30 分钟的等效值是多少？
Below follows the code:
下面是代码：
_timer.Tick += new EventHandler(_timer_Tick);
_timer.Interval = (1000) * (1);
_timer.Enabled = true;
_timer.Start();
void _timer_Tick(object sender, EventArgs e)
{
_ticks++;
if (_ticks == 15)
{
if (!backgroundWorker1.IsBusy)
{
backgroundWorker1.RunWorkerAsync();
}
_ticks = 0;
}
}
I am not sure if this is the best way or if anyone has a better suggestion.
我不确定这是否是最好的方法，或者是否有人有更好的建议。

The Intervalproperty of a timer is specified in milliseconds, not ticks.
计时器的Interval属性以毫秒为单位指定，而不是滴答。
Therefore, for a timer which fires every 30 minutes, simply do:
因此，对于每 30 分钟触发一次的计时器，只需执行以下操作：
// 1000 is the number of milliseconds in a second.
// 60 is the number of seconds in a minute
// 30 is the number of minutes.
_timer.Interval = 1000 * 60 * 30;
However, I'm not clear what the Tickevent you use is. I think you mean Elapsed?
但是，我不清楚Tick您使用的事件是什么。我想你的意思是Elapsed？
EDITAs CodeNaked makes clear, you are talking about the System.Windows.Forms.Timer, not the System.Timers.Timer. Luckily, my answer applies to both :)
编辑正如 CodeNaked 所说，你在谈论System.Windows.Forms.Timer，而不是System.Timers.Timer。幸运的是，我的回答适用于两者:)
Finally, I don't understand why you maintain a count (_ticks) within your timer_Tickmethod. You should re-write it as follows:
最后，我不明白你为什么_ticks在你的timer_Tick方法中维护一个 count ( ) 。您应该按如下方式重新编写它：
void _timer_Tick(object sender, EventArgs e)
{
if (!backgroundWorker1.IsBusy)
{
backgroundWorker1.RunWorkerAsync();
}
}

Didn't get the question well. But if u just want the interval of 30 minutes then give timer1.interval = 1800000;
没有很好地回答这个问题。但是如果你只想要 30 分钟的间隔，那么给 timer1.interval = 1800000;
// There are 10,000 ticks in a millisecond (Dont forget this )
// 一毫秒有 10,000 个滴答声（不要忘记这一点）

To make the code more readable, you can use the TimeSpanclass:
为了使代码更具可读性，您可以使用TimeSpan该类：
_timer.Interval = TimeSpan.FromMinutes(30).TotalMilliseconds;

using Timer = System.Timers.Timer;
[STAThread]
static void Main(string[] args) {
Timer t = new Timer(1800000); // 1 sec = 1000, 30 mins = 1800000
t.AutoReset = true;
t.Elapsed += new System.Timers.ElapsedEventHandler(t_Elapsed);
t.Start();
}
private static void t_Elapsed(object sender, System.Timers.ElapsedEventArgs e) {
// do stuff every 30 minute
}
