Bonsoir à tous,
J'arrive à serializer une classe sauf les membres déclarés "Shared" comme ceci :

Savez vous comment Serializer les membres partagés comme par exemple la propriété NbFrames ?

En vous remerciant par avance.

[Pol63]

ca me paraitrait étrange que ca soit faisable, shared veut dire partagé, et la sérialisation se fait sur des instances ...

après tu peux bricoler à faire une propriété qui pointe vers la propriété shared ...

Bonsoir, merci de m'avoir répondu Pol63.
J'ai du faire une serialization personnalisée comme ceci :
(J'espère ne pas avoir fait une mauvaise utilisation des fonctionnalités du FrameWork VB.NET comme ça m'arrive parfois....mais apriori ça fonctionne très bien).
