   BitVector32 myBV(0);

   // Creates four sections in the BitVector32 with maximum values 6, 3, 1, and 15.

Remarques

Utilisez CreateSection pour définir une nouvelle section. Un BitVector32.Section est une fenêtre dans le BitVector32 et est composé du plus petit nombre de bits consécutifs pouvant contenir la valeur maximale spécifiée dans CreateSection. Par exemple, une section avec une valeur maximale de 1 est composée d’un seul bit, tandis qu’une section avec une valeur maximale de 5 est composée de trois bits. Vous pouvez créer un BitVector32.Section avec une valeur maximale de 1 pour servir de booléen, ce qui vous permet de stocker des entiers et des booléens dans le même BitVector32.

Propriétés

Mask	Obtient un masque qui isole cette section dans BitVector32.
Offset	Obtient l'offset de cette section à partir du début du BitVector32.

Méthodes

Equals(BitVector32+Section)	Détermine si l'objet BitVector32.Section spécifié correspond à l'objet BitVector32.Section en cours.
Equals(Object)	Détermine si l'objet spécifié correspond à l'objet BitVector32.Section en cours.
GetHashCode()	Est utilisé comme fonction de hachage pour l'élément BitVector32.Section actuel, et convient aux algorithmes de hachage et aux structures de données, comme une table de hachage.
ToString()	Retourne une chaîne qui représente le BitVector32.Section actuel.
ToString(BitVector32+Section)	Retourne une chaîne qui représente le BitVector32.Section spécifié.

Opérateurs

Equality(BitVector32+Section, BitVector32+Section)	Détermine si deux objets BitVector32.Section spécifiés sont identiques.
Inequality(BitVector32+Section, BitVector32+Section)	Détermine si deux objets BitVector32.Section ont des valeurs différentes.
