It implements the IStackWalk interface and independently implements the Copy( ), Demand( ), Intersect( ), IsSubsetOf( ), and Union( ) methods, which mirror those defined by the IPermission interface. This functionality allows a PermissionSet object to be treated as an individual IPermission object for imperative security operations, but the security operation is performed on all contained IPermission objects at once. The contents of a PermissionSet are configured using the AddPermission( ), RemovePermission( ), and SetPermission( ) methods. Only one of each permission type can be present in a PermissionSet at a time. When you call AddPermission( ), if a permission of the same type already exists in the PermissionSet, the existing IPermission is replaced by a new IPermission whose value is calculated as the union of the existing and new IPermission objects. Conversely, SetPermission( ) replaces the existing permission with the specified one. The GetPermission( ) method returns a copy of the IPermission of the specified System.Type if one exists in the PermissionSet.
