问题描述
就是这样 - 如何将计时器添加到 C# 控制台应用程序?如果您能提供一些示例编码，那就太好了.
Just this - How do you add a timer to a C# console application? It would be great if you could supply some example coding.
推荐答案
这很好，但是为了模拟一些时间流逝，我们需要运行一个需要一些时间的命令，这在第二个示例中非常清楚.
That's very nice, however in order to simulate some time passing we need to run a command that takes some time and that's very clear in second example.
但是，使用 for 循环来执行某些功能的方式永远会占用大量设备资源，而我们可以使用垃圾收集器来执行类似的操作.
However, the style of using a for loop to do some functionality forever takes a lot of device resources and instead we can use the Garbage Collector to do some thing like that.
我们可以在同一本书 CLR Via C# Third Ed 的代码中看到这种修改.
We can see this modification in the code from the same book CLR Via C# Third Ed.
using System;
using System.Threading;
public static class Program
{
private Timer _timer = null;
public static void Main()
{
// Create a Timer object that knows to call our TimerCallback
// method once every 2000 milliseconds.
_timer = new Timer(TimerCallback, null, 0, 2000);
// Wait for the user to hit <Enter>
Console.ReadLine();
}
private static void TimerCallback(Object o)
{
// Display the date/time when this method got called.
Console.WriteLine("In TimerCallback: " + DateTime.Now);
}
}
