PagesSection クラスとは? わかりやすく解説

PagesSection クラス

メモ : このクラスは、.NET Framework version 2.0新しく追加されたものです。

構成ファイルpages 要素 (ASP.NET 設定スキーマ) セクションプログラムかアクセスできるようにします。このクラス継承できません。

この例では、pages セクション複数属性に対して宣言によって値を指定する方法示してます。これらの属性には、PagesSection クラスメンバとしてもアクセスできます

次の構成ファイルの例では、pages 要素 (ASP.NET 設定スキーマ) セクションに対して宣言によって値を指定する方法示してます。
