説明

ファイル操作に使用する静的なユーティリティ メソッドを多数含んでいます。

TFile は、ファイルに対してさまざまな操作を行うための静的メソッドだけを含むレコードです。TFile 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、TFile 型の変数を宣言しないでください。TFile を使って実行できる操作には、次のようなものがあります。

  • ファイルの作成、名前変更、削除。
  • ファイル内容に対する簡略化されたアクセス。
  • ファイルの属性やタイムスタンプの操作。

メモ：  TFile が公開しているメソッドのほとんどは、.NET Framework の File クラスが公開しているメソッドと互換性のあるシグニチャになっています。
