LastIndexOf Method (Char, Int32)

[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 of a specified Unicode character within this instance. The search starts at a specified character position and proceeds backward toward the beginning of the string.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public int LastIndexOf(
	char value,
	int startIndex
)

Parameters

value
Type: System..::..Char
The Unicode character to seek.
startIndex
Type: System..::..Int32
The starting position of the search. The search proceeds from startIndex toward the beginning of this instance.

Return Value

Type: System..::..Int32
The zero-based index position of value if that character is found, or -1 if it is not found or if the current instance equals String..::..Empty.

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 startIndex character position of this instance and proceeds backward toward the beginning of the current instance until either value is found or the first character position has been examined. For example, if startIndex is Length - 1, the method searches every character from the last character in the string to the beginning. The search is case-sensitive.
