L’exemple de code suivant crée un PerformanceCounterCategory avec le PerformanceCounterCategory() constructeur. Il invite l’utilisateur à entrer les noms de l’ordinateur PerformanceCounterCategory et, puis définit les CategoryName propriétés et MachineName à partir des valeurs entrées. Il affiche ensuite les valeurs des CategoryNamepropriétés , MachineNameet ou CategoryHelp affiche un message d’erreur si l’objet PerformanceCounterCategory est inaccessible.
