Description

Returns the last index of the Value string in the current 0-based string.

StartIndex specifies the offset in this 0-based string where the LastIndexOf method begins the search, and Count specifies the end offset where the search ends.

There are six LastIndexOf overloaded methods, each one allowing you to specify various options in order to obtain the last index of the given string in this 0-based string.

When the Value argument (Char or String), passed to LastIndexOf, is not found in the 0-based string, LastIndexOf function returns -1.
