about using timer to monitor network ping

Project needs to connect to a specific server, if not connected to the real-time prompt, start using timer real-time detection

void Timer_tick (object  sender, EventArgs e)        {            ping pingsender = new ping ();             = Pingsender.send ("192.168.1.104");             if (reply. Status = ipstatus.success)            {                message.show (" Network exception ")            }        }

If my timer keeps running, it will cause the memory of the program to grow, and then the test finds that it is not a timer, the timer runs without affecting the memory, the use of ping in the timer causes the problem, the ping is estimated to have a return value, no cleanup

After modifying, put ping pingsender = new Ping () out, add a pingcompleted event, release the Fix problem

void pingsender_pingcompleted (object  sender, Pingcompletedeventargs e)        {            as  IDisposable). Dispose ();        }
