IExtenderProviderService 인터페이스

아티클
08/21/2007

디자인 타임에 extender 공급자를 추가하고 제거할 수 있는 인터페이스를 제공합니다.

네임스페이스: System.ComponentModel.Design
어셈블리: System(system.dll)

구문

‘선언
Public Interface IExtenderProviderService
‘사용 방법
Dim instance As IExtenderProviderService

public interface IExtenderProviderService

public interface class IExtenderProviderService

public interface IExtenderProviderService

public interface IExtenderProviderService

설명

일반적으로 컨테이너에 추가된 구성 요소만이 extender 공급자를 제공합니다. IExtenderProviderService를 사용하면 컨테이너에 없는 개체에 이 기능을 확장할 수 있습니다.

예제

다음 예제에서는 디자이너에서 IExtenderProviderService를 사용하여 IExtenderProvider 구현을 추가하고 제거합니다.
