The Unregister method removes the authentication module with the specified authentication scheme from the list of authentication modules called by the Authenticate method. The module must have been added to the list using the Register method before it can be removed from the list.
The following example uses the Unregister method to remove an authentication module with the specified authentication scheme from the list of registered modules.
IEnumerator registeredModules = AuthenticationManager.RegisteredModules; // Display all the modules that are already registered with the system. DisplayAllModules(); registeredModules.Reset(); registeredModules.MoveNext(); // Get the first Authentication module registered with the system. IAuthenticationModule authenticationModule1 = (IAuthenticationModule)registeredModules.Current; // Call the UnRegister() method to unregister the first authentication module from the system. String authenticationScheme = authenticationModule1.AuthenticationType; AuthenticationManager.Unregister(authenticationScheme); Console.WriteLine("\nSuccessfully unregistered '{0}",authenticationModule1+"'."); // Display all modules to see that the module was unregistered. DisplayAllModules();
