在C#中每分钟检查一次

Question

我正在制作一个每隔1,5或30分钟甚至每小时通知用户的应用程序.例如,用户在5:06打开程序,程序将在6:06通知用户.

所以我当前的代码使用Thread.Sleep()函数每隔5分钟通知用户,但我发现它有点蹩脚.

这是我的代码:

public void timeIdentifier()
    {
        seiyu.SelectVoiceByHints(VoiceGender.Female);
        while(true)
        {
            string alarm = String.Format("Time check");
            seiyu.Speak(alarm);
            string sayTime = String.Format(DateTime.Now.ToString("h:mm tt"));
            seiyu.Speak(sayTime);
            // It will sleep for 5 minutes LOL
            Thread.Sleep(300000);
        }
    }

Answer 1

您可以使用计时器而不是Thread.Sleep():

public class Program
{
    private static System.Timers.Timer aTimer;

    public static void Main()
    {
        aTimer = new System.Timers.Timer(5000); // interval in milliseconds (here - 5 seconds)

        aTimer.Elapsed += new ElapsedEventHandler(ElapsedHandler); // handler - what to do when 5 seconds elaps

        aTimer.Enabled = true;

        // If the timer is declared in a long-running method, use
        // KeepAlive to prevent garbage collection from occurring
        // before the method ends.
        //GC.KeepAlive(aTimer);
    }

    //handler
    private static void ElapsedHandler(object source, ElapsedEventArgs e)
    {
        string alarm = String.Format("Time check");
        seiyu.Speak(alarm);
        string sayTime = String.Format(DateTime.Now.ToString("h:mm tt"));
        seiyu.Speak(sayTime);
    }
}
