この記事では、妻と一緒にコンピューターを構成する際の問題を解決するために、主に C# 設計パターンのビルダー パターンを紹介します。ビルダー パターンの概念と機能を簡単に紹介し、それを具体的な例と組み合わせて C# の手順と手順を分析します。関連する操作スキルについては、必要な友人が参照できます
この記事では、妻とのコンピューターの構成の問題を解決するための C# 設計パターンのビルダー ジェネレーター モードの例について説明します。 。参考のために皆さんと共有してください。詳細は次のとおりです:
1. 理論的定義
ジェネレーター モードは、ビルダー モードとも呼ばれ、複雑なオブジェクトを段階的に作成できます。
2. アプリケーション例
要件の説明: 給料の話ですが、妻のコンピューターを設定するために江頂白納匯に行く予定です。
OK、BRT に乗って出発しましょう。
私がポストの一番上に到達したとき、美しい女性が笑顔で私に来ました：先生、どのブランドが好きですか？
みんなが話していて、おもてなしを断りにくいので、見てみましょう。

当初は各コンピューターアクセサリを改良したかったのですが、プロジェクトが非常に大きく、コンピューター製品には多くの属性があることがわかりました。したがって、2 つのフィールドのみがリストされています。
添付ファイルにはプログラムのソースコードが含まれています。コンソールや Web など、他のプロジェクトのテストも含まれます。
以上がコンピューターの構成の問題を解決するための C# のビルダー ジェネレーター モードの詳細な説明の詳細内容です。詳細については、PHP 中国語 Web サイトの他の関連記事を参照してください。
