XmlNamespaceManager.PushScope メソッド

定義

名前空間スコープをスタックにプッシュします。

public:
 virtual void PushScope();
public virtual void PushScope ();
abstract member PushScope : unit -> unit
override this.PushScope : unit -> unit
Public Overridable Sub PushScope ()

次の例では、プレフィックスと名前空間のペアをコレクションに XmlNamespaceManager 追加し、コレクション内のすべてのペアを表示します。
