Name Splitter in C#

This small program splits full name into first name, middle namd and last name. This program consider that the fullName may have either comma (,) only or spaces only. If comma appears, it splits by comma, it assumes that the first part is last name and 2nd part is first name and middle name. If only spaces appears, it splits by the number of words.

Return First Name, Last Name and Middle Name in array

Returns in array with 3 items. First one is first name, middle one is middle name and last one is last name.
