Remarks

The membership providers for an application are exposed as a read-only MembershipProviderCollection by the Providers property of the Membership class. You can access a specific membership provider in the collection by name and cast it as the specific provider type, such as SqlMembershipProvider. This enables you to manage membership information from multiple data stores in a single application as well as access custom members of a membership provider that are not part of the MembershipProvider abstract class.

Note

If you are not familiar with the membership features of ASP.NET, see Introduction to Membership before continuing. For a list of other topics related to membership, see Managing Users by Using Membership.
