c# - How to run the application continously without hanging in background -

-


have problem in running application continuously without hanging (appending data).
want run code without hanging in background every 5 seconds.

my code is:

    public void button1_click(system.object sender, system.eventargs e)     {         if (button1.text == "start")         {             timer1.interval = 5000;             timer1.enabled = true;             button1.text = "stop";         }         else if (button1.text == "stop")         {             timer1.enabled = false;             button1.text = "start";         }     }

or, can implement windows service, run in background of system without showing explicitly. in main thread can perform required actions 5 second delays.
