Remarques

Si un champ a FamANDAssem une visibilité de niveau, il peut être appelé à partir de n’importe quel membre d’une classe dérivée qui se trouve également dans le même assembly, mais pas à partir d’un autre type.

La visibilité d’un champ est exactement décrite par FieldAttributes.FamANDAssem si le modificateur de visibilité est private protected en C#, Private Protected en Visual Basic ou protected private en C++.
