DtsEventHandler.SetExpression(String, String) 메서드

정의

지정한 식을 속성에 할당합니다. 속성에서 기존 식을 제거하려면 null을 지정합니다.

public:
 virtual void SetExpression(System::String ^ propertyName, System::String ^ expression);
public void SetExpression (string propertyName, string expression);
abstract member SetExpression : string * string -> unit
override this.SetExpression : string * string -> unit
Public Sub SetExpression (propertyName As String, expression As String)

매개 변수

propertyName
String

식을 할당할 속성의 이름입니다.

expression
String

식입니다.

구현

예제

다음 코드 예제에서는 패키지를 만들고 패키지 이벤트에 대해 OnError 추가 DtsEventHandler 합니다. 사용 하 SetExpression여 속성이 FailParentOnFailure 수정됩니다. 메서드를 GetExpression 사용하여 새 값과 연결된 식이 표시됩니다.
