Syntax
'Declaration
Public Function LastIndexOf ( _
value As Char _
) As Integer
public int LastIndexOf(
char value
)
public:
int LastIndexOf(
wchar_t value
)
member LastIndexOf :
value:char -> int
public function LastIndexOf(
value : char

Parameters
- value
Type: System. . :: . .Char
The Unicode character to seek.
Return Value
Type: System. . :: . .Int32
The zero-based index position of value if that character is found, or -1 if it is not.
Remarks
Index numbering starts from zero. That is, the first character in the string is at index zero and the last is at Length - 1.
This method begins searching at the last character position of this instance and proceeds backward toward the beginning until either value is found or the first character position has been examined. The search is case-sensitive.
