A permission, permission set, or permission set collection object.

This property contains the denied permission, permission set, or permission set collection that caused the security check to fail. It is null for exceptions that are not caused by a Deny. The property is of type Object because it can contain a permission, a permission set, or a permission set collection. To test the run-time type of this property, you can use the GetType method or a specific language operator, such as the is operator in C# or the TypeOf operator in Visual Basic.
