Timercontroller in C#

Get Timer Control from ToolBox into your form and use your code with its Tick Event.

private void timer1_Tick(object sender, EventArgs e)
{
    // Do your swap code here....
}

in Timer control make it

timer1.Enabled = true;
timer1.Interval = 1000;

Here 1000 is equals to 1 sec.
