The search is case-insensitive or case sensitive depending on the value of the CaseSensitive . If a matching entry is found, its position is returned. if no matching string is found, -1 is returned.

Remark:
  1. Only the first occurrence of the string is returned.
  2. The returned position is zero-based, i.e. 0 indicates the first string in the list.
