Exemples
L’exemple suivant illustre la TreatControlCAsInput propriété.

Console.TreatControlCAsInput = true;

Remarques
Si la valeur de la TreatControlCAsInput propriété est false et que Ctrl+C est enfoncée, les touches enfoncées ne sont pas stockées dans la mémoire tampon d’entrée et le système d’exploitation met fin au processus en cours d’exécution. Il s’agit de la valeur par défaut.
Avertissement
Utilisez cette propriété judicieusement parce que la définition de true celle-ci a un effet si spectaculaire. La plupart des utilisateurs s’attendent à ce que Ctrl+C termine une application console. Si vous désactivez l’effet de Ctrl+C, l’utilisateur doit se rappeler d’utiliser Ctrl+Break pour terminer l’application, qui est une combinaison de touches moins familière.
