L'exemple suivant illustre une implémentation de la méthode ProviderProtect.The following example shows an implementation of the ProviderProtect method. Elle fait partie d’un exemple de code plus large DataProtector pour la classe.It is part of a larger code example for the DataProtector class.

// To allow a service to hand out instances of a DataProtector we demand unrestricted DataProtectionPermission 
// in the constructor, but Assert the permission when ProviderProtect is called.  This is similar to FileStream
// where access is checked at time of creation, not time of use.
