Description
Convertit le Variant.
L'opérateur de conversion renvoie un type qui est une conversion de ce Variant. Si la conversion T* est utilisée, l'opérateur positionne le bit varByRef qui signifie que le Variant contient une référence et non une valeur.
Si la conversion est impossible à cause d'une conversion de type variant incorrecte, une exception EVariantError est déclenchée.
Remarque : N'appelez pas directement l'opérateur de conversion implicite. C'est une surcharge de l'opération de conversion implicite.
