String::IndexOfAny Method (array<Char>^)

Parameters

anyOf

Type: array<System::Char>^

A Unicode character array containing one or more characters to seek.

Return Value

The zero-based index position of the first occurrence in this instance where any character in anyOf was found; -1 if no character in anyOf was found.

Index numbering starts from zero.

The search for anyOf is case-sensitive. If anyOf is an empty array, the method finds a match at the beginning of the string (that is, at index zero).

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. 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.
