| ImportMemberAttribute Class |
Custom attribute that, when applied to an instance field of an aspect class, determines
that this field should be bound to a method, event or property, of the
target class of this aspect. Valid types for fields are
a concrete Delegate (to bind to a method),
Property<TValue> or Property<TValue, TIndex>
(to bind to a property), or Event<TDelegate> (to bind to an event).

The ImportMemberAttribute type exposes the following members.
Constructors| Name | Description | |

|
| ImportMemberAttribute(String) | Initializes a new instance of the ImportMemberAttribute class |
| ImportMemberAttribute(String[]) |

|
Properties| Name | Description | |
|---|---|---|
 | Description |
A human-readable description of the current advice.
(Inherited from Advice.) |
| IsRequired |
Determines whether a build time error must be issued if the member to be
imported is absent. If false, the binding field will be null
in case the imported member is absent.
|
| LinesOfCodeAvoided |
Reduction in the code lines count achieved by applying the advice instance to one code element.
(Inherited from Advice.) |
| MemberName | Obsolete.
Name of the imported member.
|
| MemberNames |
Array of possible names of imported member in the order of precedence.
|
| Order |
Determines when the member should be imported: either before (BeforeIntroductions)
or after (AfterIntroductions) members have been introduced by the current aspect.
Default is BeforeIntroductions.
|
Extension Methods| Name | Description | |
|---|---|---|
 | QueryInterface<T> |
Gets the implementation of a specified interface for the specified object.
(Defined by QueryInterfaceExtensions.) |
RemarksFields annotated with the ImportMemberAttribute custom attribute must be public and must not be read only.
At runtime, these fields are assigned to a delegate (in case of method binding) or a pair of delegates (in case of event or property binding) allowing to invoke the imported member.
When IsRequired property is set to true and the target type does not contain a member of the required name and signature, then a build error will be raised.
When multiple member names are specified, the first existing member satisfying all conditions is used.
