Uwagi

Aplikacje klienckie używają konfiguracji globalnej, która ma zastosowanie do wszystkich użytkowników, oddzielnych konfiguracji, które mają zastosowanie do poszczególnych użytkowników, oraz konfiguracji, które mają zastosowanie do użytkowników mobilnych. Parametr userLevel określa lokalizację otwieranego pliku konfiguracji, wskazując, czy nie ma poziomu użytkownika (plik konfiguracji znajduje się w tym samym katalogu co aplikacja) lub ma poziom na użytkownika (plik konfiguracji znajduje się w ścieżce ustawień aplikacji określonej przez poziom użytkownika).

Określ konfigurację, która ma być pobierana, przekazując jedną z następujących wartości dla userLevelelementu :

• Aby uzyskać Configuration obiekt, który ma zastosowanie do wszystkich użytkowników, ustaw wartość userLevelNone.

• Aby uzyskać obiekt lokalny Configuration , który ma zastosowanie do bieżącego użytkownika, ustaw wartość userLevelPerUserRoamingAndLocal.

• Aby uzyskać obiekt roamingu Configuration , który ma zastosowanie do bieżącego użytkownika, ustaw wartość userLevelPerUserRoaming.

  Uwaga

  Aby uzyskać Configuration obiekt dla zasobu, kod musi mieć uprawnienia do odczytu dla wszystkich plików konfiguracji, z których dziedziczy ustawienia. Aby zaktualizować plik konfiguracji, kod musi dodatkowo mieć uprawnienia do zapisu zarówno dla pliku konfiguracji, jak i katalogu, w którym istnieje.
