注釈

インデックス番号は 0 から始まります。

の anyOf 検索では、大文字と小文字が区別されます。 が空の配列の場合 anyOf 、メソッドは文字列の先頭 (つまりインデックス 0) で一致を検索します。

このメソッドは序数 (カルチャに依存しない) 検索を実行します。この検索では、Unicode スカラー値が同じ場合にのみ、文字が別の文字と等価であると見なされます。 カルチャに依存する検索を実行するには、 メソッドを使用 CompareInfo.IndexOf します。ここで、合字 "Æ" (U+00C6) などの事前計算済み文字を表す Unicode スカラー値は、カルチャに応じて"AE" (U+0041、U+0045) など、正しいシーケンス内の文字のコンポーネントの出現と同じと見なされる場合があります。
