Remarques
Si la FormsAuthenticationTicket valeur est créée à l’aide du FormsAuthenticationTicket(String, Boolean, Int32) constructeur qui ne fournit pas de paramètre pour une date et une heure d’expiration, la Expiration propriété retourne une valeur basée sur la date et l’heure locales actuelles, ainsi que la valeur du timeout
paramètre fourni au constructeur.
Si le FormsAuthenticationTicket constructeur a été créé à l’aide d’un expiration
paramètre, la Expiration propriété retourne la valeur fournie au expiration
paramètre.
