Source:

CounterCreationDataCollection.cs

CounterCreationData 인스턴스가 컬렉션에 있는지 여부를 확인합니다.

public:
 bool Contains(System::Diagnostics::CounterCreationData ^ value);

public bool Contains (System.Diagnostics.CounterCreationData value);

member this.Contains : System.Diagnostics.CounterCreationData -> bool

Public Function Contains (value As CounterCreationData) As Boolean

매개 변수

value

CounterCreationData

컬렉션에서 찾을 CounterCreationData 개체입니다.

반환

Boolean

지정된 CounterCreationData 개체가 컬렉션에 있으면 true이고, 그렇지 않으면 false입니다.

예제

다음 예제에서는 메서드를 사용하여 Contains 에서 개체를 CounterCreationData 찾는 방법을 보여 줍니다 CounterCreationDataCollection.
