Timer.Start Method ()


Starts the timer.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public void Start()

You can also start the timer by setting the Enabled property to true.

The following code example implements a simple interval timer, which sets off an alarm every five seconds. When the alarm occurs, a MessageBox displays a count of the number of times the alarm has started and prompts the user whether the timer should continue to run.

public class Class1 {
    static System.Windows.Forms.Timer myTimer = new System.Windows.Forms.Timer();
    static int alarmCounter = 1;
    static bool exitFlag = false;

    // This is the method to run when the timer is raised.
    private static void TimerEventProcessor(Object myObject,
                                            EventArgs myEventArgs) {

       // Displays a message box asking whether to continue running the timer.
       if(MessageBox.Show("Continue running?", "Count is: " + alarmCounter, 
          MessageBoxButtons.YesNo) == DialogResult.Yes) {
          // Restarts the timer and increments the counter.
          alarmCounter +=1;
          myTimer.Enabled = true;
       else {
          // Stops the timer.
          exitFlag = true;

    public static int Main() {
       /* Adds the event and the event handler for the method that will 
          process the timer event to the timer. */
       myTimer.Tick += new EventHandler(TimerEventProcessor);

       // Sets the timer interval to 5 seconds.
       myTimer.Interval = 5000;

       // Runs the timer, and raises the event.
       while(exitFlag == false) {
          // Processes all the events in the queue.
    return 0;
