Examples

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="2.0.0.0")]
    [QualificationData("Isolation", "NewAppDomain")]
    public class SampleV2AddIn : Calculator2
    {

' 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:="2.0.0.0")> _
<QualificationData("Isolation", "NewAppDomain")> _
    Public Class SampleV2AddIn

Remarks

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.

Constructors

AddInAttribute(String)

Initializes a new instance of the AddInAttribute class.

Properties

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.

Methods

Equals(Object)	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(Object)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)

Explicit Interface Implementations

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)	Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)	Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute)
_Attribute.GetTypeInfoCount(UInt32)	Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)	Provides access to properties and methods exposed by an object. (Inherited from Attribute)
