Assembly: System.Web (in system.web.dll)
The role providers for an application are exposed as a read-only RoleProviderCollection by the Providers property of the Roles class. You can access a specific role provider in the collection by name and cast it as the specific provider type, such as SqlRoleProvider. This enables you to manage role information from multiple data stores in a single application as well as access custom members of a role provider that are not part of the RoleProvider abstract class.
The following code example lists the providers enabled for an application and their respective types.
