Question

所以我想从我的class开始检查时间，当time通过时（1分钟）我想提出事件：

public class TimeOut
{
    private readonly int TIME_OUT = 60;
    private System.Timers.Timer _timer;
    private Stopwatch _stopwatch;
    public event TimeOutHandler TimePassed;

    public void Initiate()
    {
        _timer = new System.Timers.Timer();
        _timer.Interval = 1000;
        _timer.Elapsed += _timer_Elapsed;
        _stopwatch = new Stopwatch();
    }

    public void Start()
    {
        _stopwatch.Start();
        _timer.Start();
    }

    public void _timer_Elapsed(object sender, ElapsedEventArgs e)
    {
        if (_stopwatch.ElapsedMilliseconds / 1000 >= TIME_OUT)
        {
            if (TimePassed!=null)
            {
                TimePassed(sender, null);
                Stop();
            }
        }
    }

    public void Stop()
    {
        _timer.Stop();
        _stopwatch.Stop();
    }
}

用法

TimeOut timeOut = new TimeOut();
timeOut.TimePassed += timeOut_TimePassed;
timeOut.Initiate();
timeOut.Start();

private void timeOut_TimePassed(object sener, System.EventArgs e)
{

}

所以我不知道为什么，但似乎我的timer elapsed函数从未启动过。我尝试_timer.Enabled = true;代替_timer.Start();，但现在仍有帮助。

等了1分钟后，它为我打了电话。

但是，你的代码只是从复制和粘贴中编译而来。将事件更改为委托，我必须使您的私有方法保持静态。

也不确定问题的最后一点，但至少在我的情况下，控制台立即关闭。所以我在最后添加了Console.Read（）以等待计时器过去。 var x仅用于断点

希望这有帮助

using System;
using System.Diagnostics;
using System.Linq;
using System.Collections.Generic;
using System.Timers;


namespace ConsoleApplication4
{
    class Program
    {
        static void Main(string[] args)
        {
            TimeOut timeOut = new TimeOut();
            timeOut.TimePassed += timeOut_TimePassed;
            timeOut.Initiate();
            timeOut.Start();

            Console.Read();
        }

        // Changed this
        private static void timeOut_TimePassed(object sener, System.EventArgs e)
        {
            var x = 1;
        }
    }

    public class TimeOut
    {
        private readonly int TIME_OUT = 60;
        private System.Timers.Timer _timer;
        private Stopwatch _stopwatch;
        // Changed this
        public delegate void TimeOutHandler(object sener, EventArgs e);
        public event TimeOutHandler TimePassed;

        public void Initiate()
        {
            _timer = new System.Timers.Timer();
            _timer.Interval = 1000;
            _timer.Elapsed += _timer_Elapsed;
            _stopwatch = new Stopwatch();
        }

        public void Start()
        {
            _stopwatch.Start();
            _timer.Start();
        }

        public void _timer_Elapsed(object sender, ElapsedEventArgs e)
        {
            if (_stopwatch.ElapsedMilliseconds / 1000 >= TIME_OUT)
            {
                if (TimePassed != null)
                {
                    TimePassed(sender, null);
                    Stop();
                }
            }
        }

        public void Stop()
        {
            _timer.Stop();
            _stopwatch.Stop();
        }
    }
}
