anyOf

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

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.

Exception Type	Condition
ArgumentNullException	anyOf is a null reference ( Nothing in Visual Basic ).

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.
