AddInAttribute AddInAttribute AddInAttribute AddInAttribute Class

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
type AddInAttribute = class
    inherit Attribute
Public NotInheritable Class AddInAttribute
Inherits Attribute

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.

FindAddIn方法以独占方式找到外接程序时, 不需要此属性。This 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) AddInAttribute(String) AddInAttribute(String) AddInAttribute(String)

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