Syntax

public abstract class EventInterceptionArgs : AdviceArgs

The EventInterceptionArgs type exposes the following members.

Properties

	Name	Description
	Arguments	Gets the delegate arguments.
	Binding	Gets an interface that allows to invoke the next node in the chain of invocation of the intercepted method.
	DeclarationIdentifier	Gets the DeclarationIdentifier of the declaration to which the advice has been applied. (Inherited from AdviceArgs.)
	Event	Gets the event to which the current aspect has been applied.
	Handler	Gets the delegate being added, removed, or invoked.
	Instance	Gets or sets the object instance on which the method is being executed. (Inherited from AdviceArgs.)
	ReturnValue	Gets the return value of the delegate.

Methods

	Name	Description
	AddHandler	Adds a handler to the event by invoking the Add semantic of the next node in the chain of invocation.
	InvokeHandler	Invokes a handler by calling the Invoke semantic of the next node in the chain of invocation.
	ProceedAddHandler	Proceeds with adding the Delegate to the event to which the current aspect. This method invokes the next handler in chain. It is typically invoked from the implementation of OnAddHandler(EventInterceptionArgs).
	ProceedInvokeHandler	Proceeds with invoking the Delegate with the arguments specified in the Arguments property. The delegate may change the Arguments and set the ReturnValue. This method invokes the next handler in chain. It is typically invoked from the implementation of OnInvokeHandler(EventInterceptionArgs).
	ProceedRemoveHandler	Proceeds with removing the Delegate from the event to which the current aspect. This method invokes the next handler in chain. It is typically invoked from the implementation of OnRemoveHandler(EventInterceptionArgs).
	RemoveHandler	Removes a handler from the event by invoking the Remove semantic of the next node in the chain of invocation.

Remarks

Note
As a result of weaving optimizations, instances of classes derived from AdviceArgs may be shared among different aspects. Therefore, aspect code should not attempt to access this object once the control has been given over to the next node in the chain of invocation. Consider working with aspect bindings if you need such deferred execution.

Note
Aspect weaving optimizations may also cause an advice parameter of this type to be seen null when inspecting it in a debugger. If you need to inspect the instance in runtime, consider disabling aspect optimizations in the debug build configuration.
