LastIndexOfAny Method (Char[], Int32, Int32)

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Reports the zero-based index position of the last occurrence in this instance of one or more characters specified in a Unicode array. The search starts at a specified character position and proceeds backward toward the beginning of the string for a specified number of character positions.

Type: array<System..::..Char>[]()[][]
A Unicode character array containing one or more characters to seek.
Type: System..::..Int32
The search starting position. The search proceeds from startIndex toward the beginning of this instance.
Type: System..::..Int32
The number of character positions to examine.

Return Value

Type: System..::..Int32
The index position of the last occurrence in this instance where any character in anyOf was found; -1 if no character in anyOf was found or if the current instance equals String..::..Empty.

Index numbering starts from zero.

This method begins searching at the startIndex character position of this instance and proceeds backward toward the beginning until either a character in anyOf is found or count character positions have been examined. The search is case-sensitive.
