public int LastIndexOf(
	string value
)

Parameters

value
Type: System..::..String
The string to seek.

Return Value

Type: System..::..Int32
The zero-based index position of value if that string is found, or -1 if it is not. If value is String..::..Empty, the return value is the last index position in this instance.

Index numbering starts from zero. That is, the first character in the string is at index zero and the last is at Length - 1.

The search begins 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.
