我想每小时执行一个方法.我写了一些代码，但这对我的目标来说还不够.下面的代码每 60 分钟工作一次.

I want to execute a method every hour on the hour. I wrote some code,but it is not enough for my aim. Below code is working every 60 minutes.

public void Start()
{
    System.Threading.Timer timerTemaUserBilgileri = new System.Threading.Timer(new System.Threading.TimerCallback(RunTakip), null, tmrTemaUserBilgileri, 0);
}

public void RunTakip(object temauserID)
{
    try 
    {
        string objID = "6143566557387";
        EssentialMethod(objID);
        TimeSpan span = DateTime.Now.Subtract(lastRunTime);
        if (span.Minutes > 60)
        {
            tmrTemaUserBilgileri = 1 * 1000;
            timerTemaUserBilgileri.Change(tmrTemaUserBilgileri, 0);
        }
        else
        {
            tmrTemaUserBilgileri = (60 - span.Minutes) * 60 * 1000;
            timerTemaUserBilgileri.Change(tmrTemaUserBilgileri, 0);
        }
        watch.Stop();
        var elapsedMs = watch.ElapsedMilliseconds;
    }
    catch (Exception ex)
    {
        timerTemaUserBilgileri.Change(30 * 60 * 1000, 0);
        Utils.LogYaz(ex.Message.ToString());
    }
}

public void EssentialMethod(objec obj)
{
    //some code
    lastRunTime = DateTime.Now;
    //send lastruntime to sql 
}

推荐答案

如果您希望代码每 60 分钟执行一次:

If you want your code to be executed every 60 minutes:

aTimer = new System.Timers.Timer(60 * 60 * 1000); //one hour in milliseconds
aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
aTimer.Start();
private static void OnTimedEvent(object source, ElapsedEventArgs e)
{
    //Do the stuff you want to be done every hour;
}

如果您希望您的代码每小时执行一次(即 1:00、2:00、3:00)，您可以创建一个具有一些小间隔(假设为一秒，取决于您需要的精度)和内部的计时器那个计时器事件检查一个小时是否已经过去

if you want your code to be executed every hour (i.e. 1:00, 2:00, 3:00) you can create a timer with some small interval (let's say a second, depends on precision you need) and inside that timer event check if an hour has passed

aTimer = new System.Timers.Timer(1000); //One second, (use less to add precision, use more to consume less processor time
int lastHour = DateTime.Now.Hour;
aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
aTimer.Start();
private static void OnTimedEvent(object source, ElapsedEventArgs e)
{
    if(lastHour < DateTime.Now.Hour || (lastHour == 23 && DateTime.Now.Hour == 0))
     {
           lastHour = DateTime.Now.Hour;
           YourImportantMethod(); // Call The method with your important staff..
     }

}
