Timers are used to perform tasks at specific intervals of time (Do X every Y seconds) Below is an example of creating a new instance of a Timer.

NOTE: This applies to Timers using WinForms. If using WPF, you may want to look into DispatcherTimer

using System.Windows.Forms; //Timers use the Windows.Forms namespace

public partial class Form1 : Form
{

    Timer myTimer = new Timer(); //create an instance of Timer named myTimer

    public Form1()
    {
        InitializeComponent();
    }

}
