[ VB ]
<Serializable>
Overloads Public Function LastIndexOfAny ( _
   ByVal anyOf ( ) As Char, _
   ByVal startIndex As Integer _
) As Integer

[ C# ]
[ Serializable ]
public int LastIndexOfAny (
   char [ ] anyOf,
   int startIndex
);

[ C++ ]
[ Serializable ]
public: int LastIndexOfAny (
   __wchar_t anyOf __gc [ ],
   int startIndex
);

[ JScript ]
public Serializable
function LastIndexOfAny (
   anyOf : Char [ ],
   startIndex : int
) : int;

Parameters

anyOf
A Unicode character array containing one or more characters to seek.
startIndex
The search starting position.

Return Value

The positive integer index of the last occurrence in the given String where any character in anyOf was found; otherwise, -1 if no character in anyOf was found.

Exceptions


Exception Type Condition
ArgumentNullException anyOf is a null reference ( Nothing in Visual Basic ).
ArgumentOutOfRangeException startIndex specifies a position not within the given String.

Remarks

This method begins searching at the startIndex character position of this instance and precedes backwards towards the beginning until either a character in anyOf is found or the first character position has been examined. The search 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.
