我试图制作一个每5秒运行一次代码的计时器。但是这5秒只能在当前代码运行完毕后计算。
示例:
static void Main(string[] args)
{
System.Timers.Timer timer = new System.Timers.Timer(5000);
timer.Elapsed += (obj, ev) =>
{
System.IO.File.AppendAllLines(@"D:\test.txt", new string[] { DateTime.Now.ToString("dd/MM/yyyy hh:mm:ss") }, Encoding.UTF8);
System.Threading.Thread.Sleep(3000);
System.IO.File.AppendAllLines(@"D:\test.txt", new string[] { DateTime.Now.ToString("dd/MM/yyyy hh:mm:ss") + " - New" }, Encoding.UTF8);
};
timer.Start();
Console.ReadLine();
}
结果:
22/03/2014 06:39:36
22/03/2014 06:39:39 - New
22/03/2014 06:39:41
22/03/2014 06:39:44 - New
22/03/2014 06:39:46
22/03/2014 06:39:49 - New
22/03/2014 06:39:51
22/03/2014 06:39:54 - New
22/03/2014 06:39:56
22/03/2014 06:39:59 - New
22/03/2014 06:40:01
22/03/2014 06:40:04 - New
22/03/2014 06:40:06
预期结果:
22/03/2014 06:39:36
22/03/2014 06:39:39 - New
22/03/2014 06:39:44
22/03/2014 06:39:47 - New
22/03/2014 06:39:52
22/03/2014 06:39:55 - New
22/03/2014 06:40:00
22/03/2014 06:40:03 - New
22/03/2014 06:40:08
22/03/2014 06:40:11 - New
22/03/2014 06:40:16
22/03/2014 06:40:19 - New
22/03/2014 06:40:24
有没有办法只计算当前事件结束后经过的时间 ?
一件重要的事情:我可以使用的唯一类是System.Timer.Timer,我不能使用Thread.Sleep或任何类型的递归方法。
谢谢,感谢您的回答=)

也许AutoReset属性可以提供帮助。
static void Main(string[] args)
{
System.Timers.Timer timer = new System.Timers.Timer(5000);
timer.Elapsed += (obj, ev) =>
{
System.IO.File.AppendAllLines(@"D:\test.txt", new string[] { DateTime.Now.ToString("dd/MM/yyyy hh:mm:ss") }, Encoding.UTF8);
System.Threading.Thread.Sleep(3000);
System.IO.File.AppendAllLines(@"D:\test.txt", new string[] { DateTime.Now.ToString("dd/MM/yyyy hh:mm:ss") + " - New" }, Encoding.UTF8);
//if you want to be sure it will execute, wrap the code above with try... catch
timer.Start();
};
timer.AutoReset = false;
timer.Start();
Console.ReadLine();
}
