- anyOf
- A Unicode character array containing one or more characters to seek.
- startIndex
- The search starting position.
- count
- The number of character positions to examine.
The positive integer index of the first occurrence in the given String where any character in anyOf was found; otherwise, -1 if no character in anyOf was found.
The search begins at startIndex and continues to startIndex + count-1. The character at startIndex + count is not included in the search.
Index numbering starts from zero.
The search for anyOf is case-sensitive.
This method performs an ordinal ( culture-insensitive ) search, where a character is considered equivalent to another character only if the Unicode values are the same. To perform a culture-sensitive search, use the CompareInfo.IndexOf method, where a Unicode 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.
