Mon problème est que quand j'appuie sur le bouton select de Addreservation, le debogueur se stop ( en fermant le programme ) avant le constructeur de Single Reservation et je ne comprend pas la raison.

Mon code est-il correct ou il y a certaine chose que je dois modifier pour ameliorer son fonctionnement ?

Merci de votre aide.

Ps : Dans un forum, on n'a pas exactement compris ce que je voulais dire.

j'ai bien essayé le try catch et aussi de cocher l'exception il se trouve que le problème doit être autre car mon compilateur m'affiche un message au moment du bogue avec une croix dans un rond rouge avec un message d'erreur
le débogueur ne peut pas continuer à afficher le processus. Le processus a été arrêté
