Custom attribute that, when applied on a method of an aspect class, specifies that this method is an advice that has the same semantics as OnRemoveHandler(EventInterceptionArgs).
Namespace: PostSharp.Aspects.Advices
Assembly: PostSharp.dll
Syntax
[AttributeUsage(AttributeTargets.Method, AllowMultiple = true, Inherited = true)]
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
A master advice without a custom attribute derived from Pointcut applies to the event to which the aspect is applied; when the aspect is applied to another kind of declaration, a pointcut is required. An advice without Master and without pointcut joins the group of the master advice declared in its class.
note
Because of the way 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.
