DtsEventHandler.Executables 속성

정의

네임스페이스:

Microsoft.SqlServer.Dts.Runtime

어셈블리:

Microsoft.SqlServer.ManagedDTS.dll

이벤트가 발생할 때 실행할 이 컨테이너의 실행 파일을 포함하는 Executables 컬렉션을 반환합니다. 이 속성은 읽기 전용입니다.

public:
 property Microsoft::SqlServer::Dts::Runtime::Executables ^ Executables { Microsoft::SqlServer::Dts::Runtime::Executables ^ get(); };

public Microsoft.SqlServer.Dts.Runtime.Executables Executables { get; }

member this.Executables : Microsoft.SqlServer.Dts.Runtime.Executables

Public ReadOnly Property Executables As Executables

속성 값

Executables

Executables 컬렉션입니다.

구현

Executables

예제

다음 코드 예제에서는 패키지에서 OnError 이벤트에 대 한 DtsEventHandler 만듭니다. 이 DtsEventHandler 컨테이너에는 두 개의 실행 파일이 포함되어 있으며 둘 사이에 우선 순위 제약 조건이 설정됩니다. 코드 예제에서는 컨테이너의 실행 파일 수를 표시한 다음, 실행 파일을 제거한 다음 개수를 다시 표시합니다.
