.NET Scheduled Task -每30分钟执行一次的WqlEventQuery

using System;
using System.Management;

class Program
{
    static void Main(string[] args)
    {
        // 创建WqlEventQuery对象
        WqlEventQuery query = new WqlEventQuery("SELECT * FROM __TimerEvent WHERE TimerID='Timer1'");

        // 创建ManagementEventWatcher对象
        ManagementEventWatcher watcher = new ManagementEventWatcher(query);

        // 设置事件处理程序
        watcher.EventArrived += new EventArrivedEventHandler(EventArrived);

        // 开始监听事件
        watcher.Start();

        // 等待用户按下任意键停止程序
        Console.WriteLine("Press any key to stop...");
        Console.ReadKey();

        // 停止监听事件
        watcher.Stop();
    }

    // 事件处理程序
    static void EventArrived(object sender, EventArrivedEventArgs e)
    {
        // 在这里执行任务的代码
        Console.WriteLine("Task executed at: " + DateTime.Now);
    }
