Uwagi

Metoda DeleteProfiles usuwa wszystkie informacje o profilu i właściwości dla określonych profilów ze źródła danych dla aplikacji określonej przez applicationName atrybut w pliku konfiguracji. Lista profilów do usunięcia jest określana jako tablica ciągów nazw użytkowników. Jeśli właściwości i informacje o profilu istnieją w źródle danych dla nazwy użytkownika w parametrze usernames , zostaną usunięte.

Wartość zwracana może różnić się od długości określonej tablicy .usernames Oznacza to, że niektóre profile w określonej tablicy usernames zostały już usunięte z magazynu danych.

Aktualizacje bazy danych wykonywane podczas wywołania DeleteProfiles metody są wykonywane w ramach transakcji. Jeśli wystąpi błąd, transakcja zostanie wycofana i nie zostaną wykonane żadne aktualizacje.

Element ProfileInfoCollection można zwrócić z GetAllProfilesmetod , , GetAllInactiveProfiles FindProfilesByUserNamei FindInactiveProfilesByUserName .

Wartość zwracana może różnić się od Count wartości podanej ProfileInfoCollectionwartości . Oznacza to, że niektóre profile w określonym ProfileInfoCollection magazynie danych nie zostały już znalezione.
