VariableDispenser.Contains(String) 메서드

정의

네임스페이스:

Microsoft.SqlServer.Dts.Runtime

어셈블리:

Microsoft.SqlServer.ManagedDTS.dll

예외를 발생시키지 않고 인덱싱을 사용하여 VariableDispenser 컬렉션에서 항목을 검색할 수 있는지 여부를 지정합니다.

public:
 bool Contains(System::String ^ variable);

public bool Contains (string variable);

member this.Contains : string -> bool

Public Function Contains (variable As String) As Boolean

매개 변수

variable

String

VariableDispenser 컬렉션에서 찾을 변수의 이름입니다.

반환

Boolean

true는 예외를 throw하지 않고 VariableDispenser[x] 구문을 사용할 수 있음을 나타냅니다. false 값은 인덱싱을 사용하여 컬렉션에서 항목을 검색할 수 없음을 나타냅니다.

예제

다음 코드 예제에서는 메서드를 VariableDispenserContains 만들고 메서드를 반환 Boolean 하여 컬렉션에서 인덱싱 구문을 사용할 수 있는지 여부를 확인합니다.
