## c\# System.Timers.Timer实现定时任务示例 ##

using System;
    
    namespace Demo1
    { 
        class Program
        { 
            static void Main(string[] args)
            { 
                System.Timers.Timer timer = new System.Timers.Timer();
                timer.Elapsed += Timer_Elapsed;
                timer.Interval = 2000;//2秒执行间隔时间
                timer.Enabled = true;
                timer.AutoReset = true;
                timer.Start();
    
                //下面的代码是防止控制台退出
                string readLine;
                do
                { 
                    readLine = Console.ReadLine();
                } while (readLine != null && readLine != "exit");
            }
    
            private static void Timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
            { 
                //得到intHour,intMinute,intSecond,当前系统时间
                //int intHour = e.SignalTime.Hour;
                //int intMinute = e.SignalTime.Minute;
                //int intSecond = e.SignalTime.Second;
                Console.WriteLine(e.SignalTime.ToString("yyyy-MM-dd HH:mm:ss"));
            }
        }
    }

前端javascript代码实现定时任务：

<!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <script>
        //每5秒执行一次myFunction()方法
        window.setInterval(myFunction, 1000 * 5);
        var i = 1;
     
        function myFunction() { 
            console.log("执行任务" + i++);
            //这里写自己的ajax请求访问后台就可以了
        }
    </script>
    <body>
    </body>
    </html>
