Type.IsContextful 속성
Type이 컨텍스트에서 호스팅될 수 있는지 여부를 나타내는 값을 가져옵니다.

‘선언
Public ReadOnly Property IsContextful As Boolean
‘사용 방법
Dim instance As Type
Dim value As Boolean
value = instance.IsContextful
public bool IsContextful { get; }

/** @property */
public final boolean get_IsContextful ()
public final function get IsContextful () : boolean
속성 값
Type이 컨텍스트에서 호스팅될 수 있으면 true이고, 그렇지 않으면 false입니다.
설명
컨텍스트에서는 클래스 멤버에 대한 호출을 가로채서 해당 클래스에 적용되는 동기화 등의 정책을 적용합니다. 원격 컨텍스트에 대한 자세한 내용은 Context를 참조하십시오.
현재 Type이 제네릭 형식 또는 제네릭 메서드 정의의 형식 매개 변수를 나타내는 경우 이 속성은 항상 false를 반환합니다.
예제
다음 예제에서는 Type 클래스의 IsContextful, IsMarshalByRef 및 IsPrimitive 속성을 보여 줍니다. 이 예제에서는 지정된 형식을 컨텍스트에서 호스팅할 수 있는지 여부, 참조에 의해 마샬링할 수 있는지 여부, 형식이 기본 데이터 형식인지 여부를 확인합니다.
