The IsUserInRole method is called by the Roles class and the IsInRole method of the Page.User property to determine whether a user is associated with a role in the SQL Server database specified in the ASP.NET application's configuration file (Web.config).

The following code example programmatically checks to see whether the logged-on user is in the Administrators role before allowing the user to view user roles. For an example of a Web.config file that enables role management, see SqlRoleProvider.
