Description

Searches for an element using linear search.

IndexOf searches for the list element Value using a linear search. The method returns the zero-based index of the first entry equal to Value. If not found, it returns -1.

Since the search is linear, it is an O(n) operation for a list with n entries. The BinarySearch method is usually faster, but requires a sorted list.
