   }
}
// The example displays the following output:
//       The first vowel in
//          The long and winding road...

注釈

インデックス番号は0から始まります。Index numbering starts from zero.

anyOf検索では、大文字と小文字が区別されます。The search for anyOf is case-sensitive. anyOf空の配列の場合、メソッドは文字列の先頭 (インデックスゼロ) で一致を検索します。If anyOf is an empty array, the method finds a match at the beginning of the string (that is, at index zero).

このメソッドは、Unicode スカラー値が同じである場合にのみ、文字が別の文字と等価であると見なされる序数 (カルチャに依存しない) 検索を実行します。This method performs an ordinal (culture-insensitive) search, where a character is considered equivalent to another character only if their Unicode scalar values are the same. カルチャに依存した検索を実行するにCompareInfo.IndexOfは、メソッドを使用します。この場合、合字の "Æ" (U + 00c6) などの構成されていない文字を表す Unicode スカラー値は、カルチャに応じて、"AE" (U + 0041 という, U + 0045) などの正しいシーケンス。To perform a culture-sensitive search, use the CompareInfo.IndexOf method, where a Unicode scalar value representing a precomposed character, such as the ligature "Æ" (U+00C6), might be considered equivalent to any occurrence of the character's components in the correct sequence, such as "AE" (U+0041, U+0045), depending on the culture.
