在C#中使用Timer

using System;
using System.Timers;

class Program
{
    static void Main()
    {
        // 创建一个新的计时器对象
        Timer timer = new Timer();

        // 设置计时器的时间间隔（以毫秒为单位）
        timer.Interval = 1000; // 1秒

        // 为计时器的Elapsed事件添加事件处理程序
        timer.Elapsed += OnTimedEvent;

        // 启动计时器
        timer.Enabled = true;

        Console.WriteLine("Press the Enter key to exit the application...");
        Console.ReadLine();
    }

    static void OnTimedEvent(Object source, ElapsedEventArgs e)
    {
        Console.WriteLine("The Elapsed event was raised at {0}", e.SignalTime);
    }
}
