Can You Help Me By Giving Some Idea Or Example?

Note that System.Timers.Timer is only one of several possible timers you can use in WinForms. I suggest you read this CodeProject article, and download/study/run its code samples, to review the different timers: "All about .NET Timers - A Comparison" [^].

This example uses a System.Timers.Timer to call a function regularly:

// timer update interval in minutes
private const int UpdateServerInterval = 5;

// timer update interval in milliseconds
private Int64 msToUpdate = new TimeSpan(0,UpdateServerInterval,0).Milliseconds;

private System.Timers.Timer UpdateServerTimer = new System.Timers.Timer;

private delegate void updateServer();

private updateServer doUpdateServer;

private void YourMainForm_Load(object sender, EventArgs e)
{
    UpdateServerTimer = new System.Timers.Timer(msToUpdate);

    // set this to true to run without stopping
    UpdateServerTimer.AutoReset = true;

    UpdateServerTimer.Elapsed += UpdateServerTimerOnElapsed;

    doUpdateServer+= DoUpdateServer;
}

// call this method to start the 'Timer
private void btnStartTheTimer_Click(object sender, EventArgs e)
{
    UpdateServerTimer.Start();
}

private void UpdateServerTimerOnElapsed(object sender, ElapsedEventArgs elapsedEventArgs)
{
    // necessary to execute the code indirectly by delegate !
    this.Invoke(doUpdateServer);
}

private void DoUpdateServer()
{
    // do the "work" of updating the server here ...
}

Note that in this example a separate Thread is not used to update: that means the WinForms UI is going to be blocked during the execution of the code in 'DoUpdateServer. My guess is that you will want to use a separate Thread for the update, depending on the design of your application, and how it is to be used at run-time.
