Remarques
Énumération de la collection en C# ou Microsoft Visual Basic
Un ResourceQualifierVectorView étant énumérable, vous pouvez utiliser une syntaxe spécifique au langage, telle que foreach en C# pour énumérer les éléments de la collection. Le compilateur effectue le casting de type pour vous et vous n’aurez pas besoin de caster IEnumerable<ResourceQualifier>
explicitement. Si vous avez besoin d’un cast explicite, par exemple si vous souhaitez appeler GetEnumerator, effectuez un cast en IEnumerable<T> avec une contrainte ResourceQualifier .
Propriétés
Size |
Obtient le nombre d’objets ResourceQualifier dans la vue. |
Méthodes
First() |
Retourne un itérateur pour énumérer les éléments de la vue. |
GetAt(UInt32) |
Retourne le ResourceQualifier à l’index spécifié dans la vue. |
GetMany(UInt32, ResourceQualifier[]) |
Retourne les objets ResourceQualifier qui commencent à l’index spécifié dans la vue. |
IndexOf(ResourceQualifier, UInt32) |
Retourne l’index d’un ResourceQualifier spécifié dans la vue. |
