Urgent Window Service Error

Hi,

I am getting an error saying

No Overload for 'OnTimedEvent' matches delegate 'System.Timers.ElapsedEventHandler' at timer.Elapsed += new ElapsedEventHandler(OnTimedEvent);

Can anyone plz help me to resolve this?


using System.ServiceProcess;
using System.Text;
using System.IO;
using System.Timers;
namespace WinServiceSample
{
public partial class ScheduledService : ServiceBase
{
Timer timer = new Timer();
public ScheduledService()
{
InitializeComponent();
}

protected override void OnStart(string[] args)
{
TraceService("Start Service");
timer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
timer.Interval = 60000;
timer.Enabled = true;
}
public void OnTimedEvent(object source, ElapsedEventHandler e)
{
TraceService("Another entry at " + DateTime.Now);
}
private void TraceService(string content)
{
FileStream fs = new FileStream(@"d:\ScheduledService.txt", FileMode.OpenOrCreate, FileAccess.Write);
StreamWriter sw = new StreamWriter(fs);
sw.BaseStream.Seek(0, SeekOrigin.End);
sw.WriteLine(content);
sw.Flush();
sw.Close();
}

protected override void OnStop()
{
timer.Enabled = false;
TraceService("Stopping Service");
}
}
}
