String.IndexOfAny Method (array<Char)
Reports the zero-based index of the first occurrence in this instance of any character in a specified array of Unicode characters.
Assembly: mscorlib (in mscorlib.dll)
'Declaration Public Function IndexOfAny ( _ anyOf As Char() _ ) As Integer
public int IndexOfAny( char anyOf )
A Unicode character array containing one or more characters to seek.
The zero-based index position of the first occurrence in this instance where any character in anyOf was found; otherwise, -1 if no character in anyOf was found.
anyOf is nulla 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 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.
