The DeleteRole method is called by the Roles class to delete a role from the SQL Server database specified in the ASP.NET application's configuration file (Web.config). When a role is deleted, the list of users associated with that role is also deleted from the database. The user information in the database is not affected.
If throwOnPopulatedRole is true, then an exception will be thrown and the role will not be deleted if the role identified by the roleName parameter has one or more members. If throwOnPopulatedRole is false, then the role will be deleted whether it is empty or not.
The following example deletes a role from the database. For an example of a Web.config file that enables role management, see SqlRoleProvider.
