QualificationDataAttribute 类

定义

提供开发人员指定的管线段数据。Provides developer-specified data for a pipeline segment.

public ref class QualificationDataAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Interface, AllowMultiple=true)]
public sealed class QualificationDataAttribute : Attribute
type QualificationDataAttribute = class
    inherit Attribute
Public NotInheritable Class QualificationDataAttribute
Inherits Attribute
继承
QualificationDataAttribute
属性

示例

下面的示例将限定数据应用于外接程序。The following example applies qualification data to 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

您可以使用此属性以名称-值字符串对的形式将数据分配给管道段。You can use this attribute to assign data, in the form of name-value string pairs, for any purpose to a pipeline segment. 例如, 可以指示应将外接程序加载到外部进程中。For example, you can indicate that an add-in should be loaded into an external process.

RebuildUpdate方法 (用于维护有关可用管道段的信息的存储区) 使用此属性来标识具有限定数据的段。The Rebuild and Update methods, which maintain the store of information about available pipeline segments, use this attribute to identify a segment that has qualification data.

若要访问管线段的限定数据, 请参见QualificationData属性。To access the qualification data for a pipeline segment, see the QualificationData property. 若要枚举所有管线段的数据, 请参阅QualificationDataItem类。To enumerate the data for all the pipeline segments, see the QualificationDataItem class.

限定数据仅由主机读取, 并且不会以任何其他方式由外接程序系统使用。Qualification data is only read by the host and is not consumed by the add-in system in any other way.

您可以通过将QualificationDataAttribute属性放置在段属性旁, 将限定数据应用于管道段。You can apply qualification data to a pipeline segment by placing a QualificationDataAttribute attribute next to the segment attribute. 有关管道段及其属性的详细信息, 请参阅管道开发For more information about pipeline segments and their attributes, see Pipeline Development.

构造函数

QualificationDataAttribute(String, String)

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

属性

Name

获取用作键/值对中的键的名称。Gets the name, which serves as a key, of a key/value pair.

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)
Value

获取键/值对的值。Gets the value of a key/value pair.

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)
