Boxing (C++/CLI)

Boxing is the process of converting a value type to the type object or to any interface type that's implemented by the value type. When the common language runtime (CLR) boxes a value type, it wraps the value in a System.Object and stores it on the managed heap. L'unboxing extrait le type valeur de l'objet. La conversion boxing est implicite ; la conversion unboxing est explicite.
