Run windows service using timer control


When the service need to run continuously in specific time interval, then we have to use timer control. In this example we will take a timer control and set the timer value 5 seconds. then the service will write a record in the log for every 5 seconds.

Code:

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Diagnostics; using System.Linq; using System.ServiceProcess; using System.Text; using System.IO; namespace WindowsServiceExample { public partial class Service1 : ServiceBase { System.Timers.Timer serviceTimer = null; string fileLocation = "C:\\servicelog.txt"; public Service1() { InitializeComponent(); serviceTimer = new System.Timers.Timer(); serviceTimer.Elapsed += new System.Timers.ElapsedEventHandler(serviceTimer_Elapsed); serviceTimer.Interval = 5 * 1000; serviceTimer.Enabled = true; serviceTimer.Start(); } protected override void OnStart(string[] args) { if (!File.Exists(fileLocation)) File.Create(fileLocation).Close(); File.AppendAllText(fileLocation, "Service started : " + DateTime.Now.ToString() + Environment.NewLine); } void serviceTimer_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { File.AppendAllText(fileLocation, "Service running at : " + DateTime.Now.ToString() + Environment.NewLine); } protected override void OnStop() { serviceTimer.Stop(); serviceTimer.Enabled = false; File.AppendAllText(fileLocation, "Service stoped : " + DateTime.Now.ToString() + Environment.NewLine); } } }
