説明
パス操作で使用される多数の静的ユーティリティ メソッドが含まれています。
TPath は、パスに対するさまざまな操作の実行に使用される静的メソッドのみ含まれているレコードです。TPath にはインスタンス メソッドやインスタンス フィールドがないため、TPath 型の変数を宣言しないでください。TPath を使って実行できる操作は以下のとおりです。
- パスまたはファイル名が正しいかどうかの確認
- パス文字列のさまざまな部分の抽出
- 一時的かつ一意なパスの生成
メモ： TPath で公開されているメソッドの大半は、.NET Framework の Path クラスで公開されているメソッドとシグニチャの互換性があります。
