Poznámky

Objekt ProfileInfoCollection obsahuje ProfileInfo objekty, které představují profily uživatelů ze zdroje dat. Je ProfileInfoCollection vrácen z GetAllProfilesmetod , GetAllInactiveProfiles, FindProfilesByUserNamea FindInactiveProfilesByUserName objektu ProfileProvider.

Do metody lze zadat DeleteProfiles parametr , ProfileInfoCollection který odstraní informace a vlastnosti profilu ze zdroje dat.

Konstruktory

ProfileInfoCollection()

Vytvoří nový, prázdný ProfileInfoCollection.

Vlastnosti

Count	Získá počet ProfileInfo objektů v kolekci.
IsSynchronized	Získá hodnotu označující, zda je shromažďování informací o profilu bezpečné z více vláken.
Item[String]	ProfileInfo Získá objekt v kolekci odkazovaný zadaným UserNameobjektem .
SyncRoot	Získá kořen synchronizace.

Metody

Add(ProfileInfo)	Přidá zadaný ProfileInfo objekt do kolekce.
Clear()	Odebere z kolekce všechny ProfileInfo objekty.
CopyTo(Array, Int32)	Zkopíruje ProfileInfoCollection do jednorozměrného pole.
CopyTo(ProfileInfo[], Int32)	Zkopíruje ProfileInfoCollection do jednorozměrného pole typu ProfileInfo.
Equals(Object)	Určí, zda se zadaný objekt rovná aktuálnímu objektu. (Zděděno od Object)
GetEnumerator()	Získá enumerátor, který může iterovat přes ProfileInfoCollection.
GetHashCode()	Slouží jako výchozí hashovací funkce. (Zděděno od Object)
GetType()	Type Získá z aktuální instance. (Zděděno od Object)
MemberwiseClone()	Vytvoří mělkou kopii aktuálního Objectsouboru . (Zděděno od Object)
Remove(String)	Odebere objekt se ProfileInfo zadaným uživatelským jménem z kolekce.
SetReadOnly()	Nastaví obsah objektu jen pro ProfileInfoCollection čtení.
ToString()	Vrátí řetězec, který představuje aktuální objekt. (Zděděno od Object)

Metody rozšíření

Cast<TResult>(IEnumerable)	Přetypuje prvky objektu na IEnumerable zadaný typ.
OfType<TResult>(IEnumerable)	Filtruje prvky objektu IEnumerable na základě zadaného typu.
AsParallel(IEnumerable)	Umožňuje paralelizaci dotazu.
AsQueryable(IEnumerable)	Převede objekt na IEnumerable IQueryable.
