cycle in C#.NET win form

Question

I have C#.NET program and I want to check something every 2 seconds until my form is closed. This cycle doesn't enable with user for other hand when user run my C#.NET form cycle is start until form closed.

For example I want to check internet connection when my form is used. I don't like checking the connection in form.load;. I want to check connection is every time.

They invented a Threaded Timer some time ago (especially for such use-cases). What have you tried? — TheGeneral, Jun 28 '19 at 07:09

Though if you need this every 2 seconds, well what if it takes more than 2 seconds to check? — TheGeneral, Jun 28 '19 at 07:19
ok . 2 second is bad choices . thank you for your answer ... — nace, Jun 28 '19 at 07:21
If you want to test Internet connection, use notification interfaces like **INetworkListManagerEvents** — Castorix, Jun 28 '19 at 07:54

this code is worked :

cycle Timer in winForm c#.NET

 using Timer = System.Windows.Forms.Timer;
 private void Form1_Load(object sender, EventArgs e)
{
    Timer MyTimer = new Timer();
    MyTimer.Interval = (45 * 60 * 1000); // 45 mins
    MyTimer.Tick += new EventHandler(MyTimer_Tick);
    MyTimer.Start();
}
private void MyTimer_Tick(object sender, EventArgs e)
{
    //Check for internet connection or some other work here
    Timer MyTimer = new Timer();
    MyTimer.Interval = (45 * 60 * 1000); // 45 mins
    MyTimer.Tick += new EventHandler(MyTimer_Tick);
    MyTimer.Start();
}

Why are you creating and starting a new timer under `MyTimer_Tick`? That's probably going to throw a StackOverflowException eventually. – 41686d6564 stands w. Palestine Jun 30 '19 at 07:56
