FieldInfo.IsStatic 속성

아티클
08/21/2007

정적 필드인지 여부를 나타내는 값을 가져옵니다.

네임스페이스: System.Reflection
어셈블리: mscorlib(mscorlib.dll)

구문

‘선언
Public ReadOnly Property IsStatic As Boolean
‘사용 방법
Dim instance As FieldInfo
Dim value As Boolean

value = instance.IsStatic

public bool IsStatic { get; }

public:
virtual property bool IsStatic {

/** @property */
public final boolean get_IsStatic ()

public final function get IsStatic () : boolean

속성 값

이 필드가 정적 필드이면 true이고, 그렇지 않으면 false입니다.

설명

정적 필드이면 필드의 복사본 중 하나를 해당 형식의 모든 인스턴스에서 공유합니다.

FieldAttributes.Static 특성이 설정될 때 IsStatic 속성이 설정됩니다.

IsStatic 속성을 가져오려면 먼저 Type 클래스를 가져옵니다. Type에서 FieldInfo를 가져옵니다. FieldInfo에서 IsStatic 속성을 가져옵니다. public이 아닌 필드에 액세스하려면 GetField 메서드에서 BindingFlags를 NonPublic으로 설정하고 액세스 가능성을 Instance 또는 Static으로 설정합니다.

예제

다음 예제에서는 지정된 필드가 static인지 여부를 확인하고 그 결과를 표시합니다.
