[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.

Syntax
'Declaration
Public Function LastIndexOfAny ( _
anyOf As Char(), _
startIndex As Integer _
) As Integer
public int LastIndexOfAny(
char[] anyOf,
int startIndex

startIndex : int
) : int
Parameters
- anyOf
Type: array<System. . :: . .Char> [] () [] []
A Unicode character array containing one or more characters to seek.
- startIndex
Type: System. . :: . .Int32
The search starting position. The search proceeds from startIndex toward the beginning of this instance.
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.
Remarks
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 the first character position has been examined. The search is case-sensitive.
