The profile providers for an application are exposed as a read-only ProfileProviderCollection through the Providers property of the ProfileManager class. You can access a specific profile provider in the collection by name and cast it as the specific provider type, such as SqlProfileProvider. This enables you to manage user profile properties from multiple data stores in a single application. It also allows you to access members of a specific profile provider that are not members of the ProfileProvider abstract class.

The following code example lists the providers enabled for an application and their respective types.
