Comentários

A numeração de índice começa do zero.Index numbering starts from zero.

A pesquisa de anyOf diferencia maiúsculas de minúsculas.The search for anyOf is case-sensitive. Se anyOf for uma matriz vazia, o método encontrará uma correspondência no início da cadeia de caracteres (ou seja, no índice zero).If anyOf is an empty array, the method finds a match at the beginning of the string (that is, at index zero).

Este método executa uma pesquisa ordinal (insensível à cultura), onde um caractere só é considerado equivalente a um outro caractere caso os valores escalares Unicode sejam os mesmos.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. Para executar uma pesquisa sensível à cultura, use o método CompareInfo.IndexOf, em que um valor escalar Unicode representando um caractere pré-composto como a ligadura "Æ" (U+00C6) pode ser considerado equivalente a qualquer ocorrência dos componentes do caractere na sequência correta, como "AE" (U+0041, U+0045), dependendo da cultura.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.
