現在開発中のMVCテンプレートは広く使用されており、データモデル、プレゼンテーション、および作業ロジックの分離を意味します。 Web開発におけるこのテンプレートの実装としては、ASP.NET MVCフレームワークがよく知られています。 少し前に、このフレームワークの3番目のバージョンがリリースされました。このバージョンでは、表現を実装するための2つのオプションがあります。ASPXとRazorです。 両方のエンジンにはかなり幅広い機能がありますが、本書では、表現を実装するための別のツール-XSLTテンプレートの使用について説明します。
XSLTテンプレートは、1つ以上の入力XMLドキュメントの出力への変換を記述するXMLドキュメントです。通常、これもXMLまたはHTMLドキュメントです。 この場合、テンプレートの入力は、対応するモデルから取得したデータのXML表現になります。 テンプレートに転送されたデータは、ページコンテンツの生成に使用されます。
主なプロジェクトは、ASP.NET MVC 3アプリケーションテンプレートです。 ここでは、ビューエンジンの選択は重要ではありません。
データモデル
リプレゼンテーションに渡されるすべてのモデルについて、次の基本クラスを説明します。
[ Serializable ]
[XmlInclude( typeof (UserModel))]
public abstract class XmlModel { }
このクラスのオブジェクトはXMLでシリアル化されるため、最初の属性が必要です。 2番目の属性を使用する理由については、以下で説明します。
UserModelは、ビューに渡す子クラスの例です。
[ Serializable ]
public class UserModel : XmlModel
{
[ XmlAttribute ]
public int UserId { get ; set ; }
public string Login { get ; set ; }
public string Email { get ; set ; }
}
次に、シリアル化されてテンプレートに渡されるメインクラスについて説明します。
