OnEventRemoveHandlerAdvice Class
Custom attribute that, when applied on a method of an aspect class, specifies that this method is an advice having the same semantics as OnRemoveHandler(EventInterceptionArgs).
Namespace: PostSharp.Aspects.Advices
Assembly: PostSharp.dll
Syntax
[RequiresEventInterceptionAdviceAnalysis]
[RequiresDebuggerEnhancement]
public sealed class OnEventRemoveHandlerAdvice : GroupingAdviceRemarks
The method to which this custom attribute is applied must be public and must have the same signature as OnRemoveHandler(EventInterceptionArgs). However, it can be static.
If an aspect defines many advices (among OnEventAddHandlerAdvice , OnEventRemoveHandlerAdvice and OnEventInvokeHandlerAdvice ) that are meant to be applied to the same events with consistent ordering, these advices should be grouped together (see Master property).
note
Standalone advices or group masters should also be annotated by a custom attribute derived from Pointcut .
note
Because of the way how the C# compiler implements
field-like events
(i.e. events where you
don't implement the
Add
and
Remove
semantics manually), the
Invoke Event Handler
semantic (
OnInvokeHandler(EventInterceptionArgs)
or equivalent) shall
not
be invoked for delegates that have been added from inside the class that declares this event.
