在for循环中以1分钟为间隔增加每个元素 [英] Increment each element by 1 minute interval in for loop

问题描述

大家早上好，

我有一个关于1分钟间隔后for循环增量的查询，即如果我在一个数组中有5个元素并且我想以1分钟间隔执行所有它们. 请帮我实现它.

Good Morning All,

I have one query regarding increment of for-loop after 1 minute interval, i.e like if I have 5 elements in an Array and I want to execute all them with 1 minute interval.
Please help me how can i achieve it.

推荐答案

您不需要真正的for循环.
您需要一个每分钟到期的计时器.
当它过期时，您将递增用作数组索引的内部变量.

例如，在客户端javascript中，您有2种window对象的方法:
setTimeout:安排函数在指定的毫秒数后运行
setInterval:相同，但重复调用该函数:var h = setInterval(callback，60000)
clearInterval:可用于清除计时器:clearInterval(h)

You don''t need a real for loop.
You need a timer that expires every minute.
When it expires you increment an internal variable that you use as index into the array.

For example in client side javascript you have 2 methods of the window object:
setTimeout : schedules a function to run after a specified number of miliseconds
setInterval : is the same but invokes the function repeatedly :var h = setInterval(callback,60000)
clearInterval : can be used to clear the timer : clearInterval(h)

Class CustomTimer
{ 
   private DateTime startTime;
    private DateTime stopTime;
    private bool running = false;

    public void Start() 
    {
        this.startTime = DateTime.Now;
        this.running = true;
    }

    public void Stop() 
    {
        this.stopTime = DateTime.Now;
        this.running = false;
    }

    //this will return time elapsed in seconds
    public double GetElapsedTimeSecs() 
    {
        TimeSpan interval;

        if (running) 
            interval = DateTime.Now - startTime;
        else
            interval = stopTime - startTime;

        return interval.TotalSeconds;
    }

}

现在在您的foreach循环中执行以下操作:

Now within your foreach loop do the following:

CustomTimer ct = new CustomTimer();
    ct.Start();
    // put your code here
    ct.Stop();   
  //timeinsecond variable will be set to time seconds for your execution.
  double timeinseconds=ct.GetElapsedTime();

您可以为定义的间隔使用长dummy for loop或使用JavaScript timer.

有关计时器，请参阅: JavaScript计时器 [

You can use a long dummy for loop for defined interval OR use a JavaScript timer.

For timer, refer: Javascript timers[^]
