public sealed class OnMethodEntryAdvice : OnMethodBoundaryAdvice

The OnMethodEntryAdvice type exposes the following members.

Constructors
  NameDescription
Public methodOnMethodEntryAdvice
Initializes a new instance of the OnMethodEntryAdvice class
Properties
  NameDescription
Public propertyDescription
A human-readable description of the current advice.
(Inherited from Advice.)
Public propertyLinesOfCodeAvoided
Reduction in the code lines count achieved by applying the advice instance to one code element.
(Inherited from Advice.)
Public propertyMaster
Name of the master advice method. If this property is not set, the current method is itself the master of the group. Only master methods can define selectors (Pointcut) and dependencies (AspectDependencyAttribute).
(Inherited from GroupingAdvice.)
Public propertySemanticallyAdvisedMethodKinds
Determines which target methods will be advised semantically. This affects the behavior of the advice when it's applied to iterator or async methods, which are compiled into state machines.
(Inherited from OnMethodBoundaryAdvice.)
Public propertyUnsupportedTargetAction
Specifies the action to take when the advice is applied to an unsupported target method.
(Inherited from OnMethodBoundaryAdvice.)
Extension Methods
  NameDescription
Public Extension MethodQueryInterface<T>
Gets the implementation of a specified interface for the specified object.
(Defined by QueryInterfaceExtensions.)
Remarks

The method to which this custom attribute is applied must be public and must have the same signature as OnEntry(MethodExecutionArgs). However, it can be static.


If an aspect defines many advices (among OnMethodEntryAdvice , OnMethodExitAdvice , OnMethodSuccessAdvice and OnMethodExceptionAdvice ) that are meant to be applied to the same methods with consistent ordering, these advices should be grouped together (see Master property).

Note Note
Standalone advices or group masters should also be annotated by a custom attribute derived from Pointcut .
