value

A Unicode character to seek.

startIndex

The starting position of a substring within the given String.

count

The number of character positions to examine.

The index position of value if that character is found, or -1 if it is not.

Exception Type	Condition
ArgumentNullException	value is a null reference ( Nothing in Visual Basic ).
ArgumentOutOfRangeException	startIndex or count is less than zero or greater than the length of this instance.

This method begins searching at the startIndex character position of this instance and precedes backwards towards the beginning until either value is found or count character positions have been examined. The search is case-sensitive.
