fonction à un intervalle de temps régulier

Question

Bonjour,

Je suis debutant en c# je cherche à lancer une fonction à un intervalle de temps régulier .

Pour faire simple j'ai une fonction MaFonction() et j'aimerai qu'elle
se declenche tous les x secondes tant que je n'arrete pas le programme.

Si quelqu'un a une idée,

Merci d'avance !

Salut,
Utilise l'espace de noms System.Timers.
Un exemple d'utilisation de msdn :

using System;
using System.Timers;

publicclass Timer1
{
privatestatic System.Timers.Timer aTimer;

publicstaticvoid Main()
    {
// Normally, the timer is declared at the class level,
// so that it stays in scope as long as it is needed.
// If the timer is declared in a long-running method,  
// KeepAlive must be used to prevent the JIT compiler 
// from allowing aggressive garbage collection to occur 
// before the method ends. (See end of method.)
//System.Timers.Timer aTimer;

// Create a timer with a ten second interval.
        aTimer = new System.Timers.Timer(10000);

// Hook up the Elapsed event for the timer.
        aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);

// Set the Interval to 2 seconds (2000 milliseconds).
        aTimer.Interval = 2000;
        aTimer.Enabled = true;

        Console.WriteLine("Press the Enter key to exit the program.");
        Console.ReadLine();

// If the timer is declared in a long-running method, use
// KeepAlive to prevent garbage collection from occurring
// before the method ends.
//GC.KeepAlive(aTimer);
    }

// Specify what you want to happen when the Elapsed event is 
// raised.
privatestaticvoid OnTimedEvent(object source, ElapsedEventArgs e)
    {
        Console.WriteLine("The Elapsed event was raised at {0}", e.SignalTime);
    }
}

/* This code example produces output similar to the following:

Press the Enter key to exit the program.
The Elapsed event was raised at 5/20/2007 8:42:27 PM
The Elapsed event was raised at 5/20/2007 8:42:29 PM
The Elapsed event was raised at 5/20/2007 8:42:31 PM
...
 */
