속성 값
연결 지점에 대한 식별자가 포함된 문자열입니다.
예제
다음 코드 예제를 사용 하는 방법을 보여 줍니다는 ID 및 ConsumerConnectionPoint 개체에 ProviderConnectionPoint 속성입니다. 이 코드 예제에서는 속성에 액세스하는 코드가 포함된 웹 페이지만 보여 줍니다. 예제를 실행하는 데 필요한 전체 코드는 클래스 개요의 예제 섹션을 ConnectionPoint 참조하세요.
웹 페이지의 메서드에 Button2_Click
있는 코드는 각 연결 지점 개체의 속성에 액세스 ID 하고 각 값을 레이블에 씁니다. 페이지가 브라우저에 로드된 후 연결점 세부 정보 단추를 클릭하여 코드를 실행합니다.

설명
개발자가 메서드를 ConnectionConsumerAttribute 연결 지점으로 사용할 수 있도록 컨트롤의 소스 코드에서 메서드에 대해 또는 ConnectionProviderAttribute 특성을 선언하는 경우 연결점 특성에 대한 매개 변수를 선언 ID
할 필요가 없습니다. 유일한 필수 특성은 매개 변수입니다 displayName
. 기본 ID는 필드의 값을 DefaultID 사용하여 연결 지점에 할당됩니다.
컨트롤에 연결점으로 사용되는 메서드가 하나만 있는 경우 연결점에 대한 ID를 지정할 필요가 없습니다. 연결점으로 지정된 메서드가 여러 개 있는 경우 각 메서드에 대한 ID를 지정해야 합니다. 그렇지 않으면 예외가 throw됩니다. 각 연결 지점에 ID를 할당하면 웹 페이지에서 연결을 선언하거나 코드에서 만들 때 사용할 연결 지점을 지정할 수도 있습니다.
