Implementing timer operation in window service

Following code snippet shows how can we perform a operation on timer event in window service:

public partial class MyService : ServiceBase
  {
      private System.Timers.Timer timer2;
      private bool IsProcessRunning = false;
    
      public MyService()
      {
          InitializeComponent();
          this.ServiceName = "MyService";
          timer2 = new System.Timers.Timer();
          timer2.Enabled = false;
          timer2.Interval = "10000";
          timer2.Elapsed += new System.Timers.ElapsedEventHandler(timer2_Elapsed);
      }

      protected override void OnStart(string[] args)
      {
          timer2.Enabled = true;
          timer2.Start();
      }

      protected override void OnStop()
      {
          // TODO: Add code here to perform any tear-down necessary to stop your service.
      }

      void timer2_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
      {
          if (!IsProcessRunning)
          {
              try
              {
                  IsProcessRunning = true;
                  // Add process here
                  InsertRecord();
              }
              catch (Exception ex)
              {
                  this.EventLog.WriteEntry(ex.Message, EventLogEntryType.Error, 1000);
              }
              finally
              {
                  IsProcessRunning = false;
              }
          }
      }
  }
