Identifies an object as an add-in.
Assembly: System.AddIn (in System.AddIn.dll)
Thetype exposes the following members.
|Description||Gets or sets the description of an add-in.|
|Name||Gets the name of the add-In.|
|Publisher||Gets or sets the publisher of the add-in.|
|TypeId||When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)|
|Version||Gets or sets the software version of the add-in.|
|Equals||Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)|
|GetHashCode||Returns the hash code for this instance. (Inherited from Attribute.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|IsDefaultAttribute||When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)|
|Match||When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|_Attribute.GetIDsOfNames||Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)|
|_Attribute.GetTypeInfo||Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)|
|_Attribute.GetTypeInfoCount||Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)|
|_Attribute.Invoke||Provides access to properties and methods exposed by an object. (Inherited from Attribute.)|
The following methods, which maintain the store of information about available pipeline segments, use this attribute to identify an add-in.
This attribute is not required when an add-in is found exclusively by the FindAddIn method. The host has already identified the add-in by its type name and location, and therefore the attribute is not required for the add-in to be discovered.
This attribute should be used only on types that activate the segments of the pipeline. Types that represent objects passed between the host and the add-in do not need this attribute.
The following example identifies an add-in.
' This pipeline segment has ' two attributes: ' 1 - An AddInAttribute to identify ' this segment as an add-in. ' ' 2 - A QualificationDataAttribute to ' indicate that the add-in should ' be loaded into a new application domain. <AddIn("Calculator Add-in", Version:="18.104.22.168")> _ <QualificationData("Isolation", "NewAppDomain")> _ Public Class SampleV2AddIn
