AssemblyCollection クラス
アセンブリ: System.Web (system.web.dll 内)
構文
AssemblyCollection クラスは、基になる構成ファイル内の実際の要素を参照しているわけではありません。このコレクションは、格納されているアセンブリ情報に簡単にアクセスできるようにする構造体です。
このセクションには、2 つのコード例が用意されています。最初の例では、AssemblyCollection クラスの複数のプロパティに対して、宣言によって値を指定する方法を示しています。2 つ目のコード例では、AssemblyCollection クラスのメンバを使用する方法を示しています。
次の構成ファイルの例では、AssemblyCollection クラスの複数のプロパティに対して、宣言によって値を指定する方法を示しています。
