Reports the index number, or character position, of the last occurrence of a specified String object in the current String object. The search starts at a specified character position and examines a specified number of character positions.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
[MethodImplAttribute]
public int LastIndexOf (
string value,
int startIndex,
int count
)
Parameters
- value
The String object you want to find. - startIndex
The starting index number for the search. - count
The number of character positions to be examined.
Return Value
The character position of the value parameter if the specified String object is found, or -1 if it is not found. If value is set to Empty, the return value is startIndex.
Remarks
The search begins at the startIndex character position in the current String object and proceeds backward toward the beginning of the string until either value is found or the number of character positions specified in the count parameter have been examined (whichever occurs first).
Index numbering starts at 0 (zero).
The search for the value parameter is both case-sensitive and culture-sensitive.
