XmlNamespaceManager.PopScope XmlNamespaceManager.PopScope XmlNamespaceManager.PopScope XmlNamespaceManager.PopScope Method

定義

名前空間スコープをスタックからポップします。Pops a namespace scope off the stack.

public:
 virtual bool PopScope();
public virtual bool PopScope ();
abstract member PopScope : unit -> bool
override this.PopScope : unit -> bool
Public Overridable Function PopScope () As Boolean

戻り値

スタックに名前空間スコープが残されている場合は true。ポップする名前空間がそれ以上ない場合は falsetrue if there are namespace scopes left on the stack; false if there are no more namespaces to pop.

次の例は、プレフィックス/名前空間のペアを追加、XmlNamespaceManagerし、コレクションのすべてのペアを表示します。The following example adds prefix/namespace pairs to the XmlNamespaceManager and then displays all the pairs in the collection.

注釈

追加されたすべての名前空間は、このメソッドを呼び出すとXmlNamespaceManager(呼び出してAddNamespace) に最後の呼び出し以降PopScopeが削除されます。When you call this method, all namespaces which were added to XmlNamespaceManager (by calling AddNamespace) since the last call to PopScope are removed.
