问题描述

The maximum interval of timer is 2,147,483,647. it's about 25 days. But in my requirements I need that the timer will wait 30 days. How can I resolve it? Please help.

推荐答案

为此使用 System.Threading.Timer .有些构造函数采用 long ， uint 或 TimeSpan 而不是 int 来构造dueTime .这些中的任何一个都可以将您设置为30天.

Use a System.Threading.Timer for this. There are constructors that take a long, a uint or a TimeSpan instead of an int for the dueTime. Any of these will let you set a period of 30 days.

更新:这是最简单的方法:

Update: this is the easiest way to do it:

System.Threading.Timer _timer;
public void Start30DayTimer()
{
    TimeSpan span = new TimeSpan(30, 0, 0, 0);
    TimeSpan disablePeriodic = new TimeSpan(0, 0, 0, 0, -1);
    _timer = new System.Threading.Timer(timer_TimerCallback, null, 
        span, disablePeriodic);
}

public void timer_TimerCallback(object state)
{
    // do whatever needs to be done after 30 days
    _timer.Dispose();
}
