XmlNamespaceManager.PopScope 메서드

정의

네임스페이스:

System.Xml

어셈블리:

System.Xml.ReaderWriter.dll

어셈블리:

System.Xml.dll

어셈블리:

netstandard.dll

스택에서 네임스페이스 범위를 팝합니다.

public:
 virtual bool PopScope();

public virtual bool PopScope ();

abstract member PopScope : unit -> bool
override this.PopScope : unit -> bool

Public Overridable Function PopScope () As Boolean

반환

Boolean

스택에 네임스페이스 범위가 남아 있으면 true이고, 팝할 네임스페이스가 없으면 false입니다.

예제

다음 예제에서는 접두사/네임스페이스 쌍을 XmlNamespaceManager 추가한 다음 컬렉션의 모든 쌍을 표시합니다.

설명

이 메서드를 호출하면 마지막 호출 PopScope 이후 (호출AddNamespace하여 XmlNamespaceManager ) 추가된 모든 네임스페이스가 제거됩니다.
