Description
Returns the last index of the Value string in the current string.
StartIndex specifies the offset in this string where the LastIndexOf method begins the search, and Count specifies the length of the searched substring.
There are six LastIndexOf overloaded methods, each allowing you to specify various options to obtain the last index of the given string in this string.
When the Value argument (Char or String), passed to LastIndexOf, is not found in the string, LastIndexOf function returns -1.
