The ProfileManager.GetAllInactiveProfiles(ProfileAuthenticationOption, DateTime) method is used to retrieve profile information from the data source for all unused user profiles for the application specified by the applicationName attribute in the configuration file. Use the authenticationOption parameter to specify whether you want only anonymous profiles, only authenticated profiles, or all profiles to be searched. Of the searched profiles, any profile is returned that has a ProfileInfo.LastActivityDate that occurs on or before the specified userInactiveSinceDate parameter value.

You can retrieve profile information for inactive user profiles in pages of data using the overload for the ProfileManager.GetAllInactiveProfiles(ProfileAuthenticationOption, DateTime, int, int, Int32@) method that takes additional pageIndex and pageSize parameters.

The ProfileManager.GetAllInactiveProfiles(ProfileAuthenticationOption, DateTime) method calls the ProfileProvider.GetAllInactiveProfiles(ProfileAuthenticationOption, DateTime, int, int, Int32@) method of the default profile provider. The default profile provider is specified using the defaultProvider attribute of the profile configuration element. If the user profile contains properties that are managed by a profile provider other than the default provider, the data source for the other profile provider is not searched. To find unused profiles that are managed by a profile provider other than the default provider, obtain a reference to the profile provider using the ProfileManager.Providers property and call the ProfileProvider.GetAllInactiveProfiles(ProfileAuthenticationOption, DateTime, int, int, Int32@) method of the provider directly.
