public abstract class Aspect : MulticastAttribute,

The Aspect type exposes the following members.

Constructors
  NameDescription
Protected methodAspect
Initializes a new instance of the Aspect class
Properties
  NameDescription
Public propertyAspectPriority
Gets or sets the weaving priority of the aspect.
Public propertyAttributeExclude
If true, indicates that this attribute removes all other instances of the same attribute type from the set of elements defined by the current instance.
(Inherited from MulticastAttribute.)
Public propertyAttributeInheritance
Determines whether this attribute is inherited
(Inherited from MulticastAttribute.)
Public propertyAttributePriority
Gets or sets the priority of the current attribute in case that multiple instances are defined on the same element (lower values are processed before).
(Inherited from MulticastAttribute.)
Public propertyAttributeReplace
Determines whether this attribute replaces other attributes found on the target declarations.
(Inherited from MulticastAttribute.)
Public propertyAttributeTargetAssemblies
Gets or sets the assemblies to which the current attribute apply.
(Inherited from MulticastAttribute.)
Public propertyAttributeTargetElements
Gets or sets the kind of elements to which this custom attributes applies.
(Inherited from MulticastAttribute.)
Public propertyAttributeTargetExternalMemberAttributes
Gets or sets the visibilities, scopes, virtualities, and implementation of members to which this attribute applies, when the member is external to the current module.
(Inherited from MulticastAttribute.)
Public propertyAttributeTargetExternalTypeAttributes
Gets or sets the visibilities of types to which this attribute applies, when this type is external to the current module.
(Inherited from MulticastAttribute.)
Public propertyAttributeTargetMemberAttributes
Gets or sets the visibilities, scopes, virtualities, and implementation of members to which this attribute applies.
(Inherited from MulticastAttribute.)
Public propertyAttributeTargetMembers
Gets or sets the expression specifying to which members this instance applies.
(Inherited from MulticastAttribute.)
Public propertyAttributeTargetParameterAttributes
Gets or sets the passing style (by value, out or ref) of parameters to which this attribute applies.
(Inherited from MulticastAttribute.)
Public propertyAttributeTargetParameters
Gets or sets the expression specifying to which parameters this instance applies.
(Inherited from MulticastAttribute.)
Public propertyAttributeTargetTypeAttributes
Gets or sets the visibilities of types to which this attribute applies.
(Inherited from MulticastAttribute.)
Public propertyAttributeTargetTypes
Gets or sets the expression specifying to which types this instance applies.
(Inherited from MulticastAttribute.)
Protected propertySerializerType
Gets or sets the Type of the serializer (a type derived from AspectSerializer) used to serialize the aspect instance at build time and deserialize it at runtime.
Methods
  NameDescription
Public methodCompileTimeValidate
Method invoked at build time to ensure that the aspect has been applied to the right target.
Protected methodCreateAspectConfiguration
Method invoked at build time to create a concrete AspectConfiguration instance specifically for the current Aspect type.
Public methodGetAspectConfiguration
Method invoked at build tome to get the imperative configuration of the current Aspect.
Protected methodSetAspectConfiguration
Method invoked at build time to set up an AspectConfiguration object according to the current Aspect instance and a specified target element of the current aspect.
Extension Methods
  NameDescription
Public Extension MethodQueryInterface<T>
Gets the implementation of a specified interface for the specified object.
(Defined by QueryInterfaceExtensions.)
Remarks

This class is not specific to any kind of declaration (method, field, type, ...). Considering deriving your aspect from TypeLevelAspect, MethodLevelAspect, LocationLevelAspect, or EventLevelAspect if it should be applied to a specific kind of declarations.


Note Note
This class does not provide any advice. You may derive your aspect class from a class providing predefined advice , or build a composite aspect .

Note Note
All classes implementing IAspect should typically be marked as serializable using the custom attribute SerializableAttribute . Fields that are only used at runtime (and unknown at compile-time) should be carefully marked with the custom attribute NonSerializedAttribute . When PostSharp is used on a platform that does not support aspect serialization (such as .NET Compact Framework, Silverlight, or Windows Phone), or when another aspect serializer is used, it is not necessary to mark the aspect class as serializable. For more information, see Aspect Serialization .
