public interface IPermissionRequest


The Security System uses Permission Requests to determine whether or not a permission is granted. Objects of the IPermissionRequest type can be passed to the SecurityStrategy.IsGranted and SecuritySystem.Demand methods when it is required to check a permission in code.

To add a custom Permission Request, declare a class that implements the IPermissionRequest interface, or inherit the OperationPermissionRequestBase class (see How to: Implement Custom Security Objects (Users, Roles, Operation Permissions)).


You can also use the IsGrantedExtensions class methods to check whether or not a permission is granted. These methods do not require an IPermissionRequest object.
