AddInAttribute 类

定义

将对象标识为外接程序。Identifies an object as an add-in.

public ref class AddInAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Class)]
public sealed class AddInAttribute : Attribute
[<System.AttributeUsage(System.AttributeTargets.Class)>]
type AddInAttribute = class
    inherit Attribute
Public NotInheritable Class AddInAttribute
Inherits Attribute
继承
AddInAttribute
属性

示例

下面的示例标识外接程序。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

注解

以下方法用于维护有关可用管道段的信息的存储区,并使用此特性来标识外接程序。The following methods, which maintain the store of information about available pipeline segments, use this attribute to identify an add-in.

当方法以独占方式找到外接程序时,不需要此属性 FindAddInThis attribute is not required when an add-in is found exclusively by the FindAddIn method. 宿主已经按类型名称和位置标识了外接程序,因此,要发现外接程序不需要该特性。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.

此属性应仅用于激活管线段的类型。This attribute should be used only on types that activate the segments of the pipeline. 表示在宿主和外接程序之间传递的对象的类型不需要此属性。Types that represent objects passed between the host and the add-in do not need this attribute.

构造函数

AddInAttribute(String)

初始化 AddInAttribute 类的新实例。Initializes a new instance of the AddInAttribute class.

属性

Description

获取或设置外接程序的说明。Gets or sets the description of an add-in.

Name

获取外接程序的名称。Gets the name of the add-In.

Publisher

获取或设置外接程序的发行者。Gets or sets the publisher of the add-in.

TypeId

在派生类中实现时,获取此 Attribute 的唯一标识符。When implemented in a derived class, gets a unique identifier for this Attribute.

(继承自 Attribute)
Version

获取或设置外接程序的软件版本。Gets or sets the software version of the add-in.

方法

Equals(Object)

返回一个值,该值指示此实例是否与指定的对象相等。Returns a value that indicates whether this instance is equal to a specified object.

(继承自 Attribute)
GetHashCode()

返回此实例的哈希代码。Returns the hash code for this instance.

(继承自 Attribute)
GetType()

获取当前实例的 TypeGets the Type of the current instance.

(继承自 Object)
IsDefaultAttribute()

在派生类中重写时,指示此实例的值是否是派生类的默认值。When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

(继承自 Attribute)
Match(Object)

当在派生类中重写时,返回一个指示此实例是否等于指定对象的值。When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

(继承自 Attribute)
MemberwiseClone()

创建当前 Object 的浅表副本。Creates a shallow copy of the current Object.

(继承自 Object)
ToString()

返回表示当前对象的字符串。Returns a string that represents the current object.

(继承自 Object)

显式接口实现

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

将一组名称映射为对应的一组调度标识符。Maps a set of names to a corresponding set of dispatch identifiers.

(继承自 Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

检索对象的类型信息,然后可以使用该信息获取接口的类型信息。Retrieves the type information for an object, which can be used to get the type information for an interface.

(继承自 Attribute)
_Attribute.GetTypeInfoCount(UInt32)

检索对象提供的类型信息接口的数量(0 或 1)。Retrieves the number of type information interfaces that an object provides (either 0 or 1).

(继承自 Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

提供对某一对象公开的属性和方法的访问。Provides access to properties and methods exposed by an object.
