Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
[MethodImplAttribute]
public int LastIndexOfAny (
char[] anyOf
)
Parameters
- anyOf
An array of Unicode characters, any one or more of whose characters you want to find in the current String object.
Return Value
The character position of the last occurrence in the current String object of any character specified in the anyOf parameter, or -1 if no such character is found.
Remarks
The search begins at the last character position in the current String object and proceeds backward toward the beginning of the string until either a character specified in the anyOf parameter is found or the first character position has been examined (whichever occurs first).
Index numbering starts at 0 (zero).
The search for the anyOf parameter is both case-sensitive and culture-sensitive.
