Language/Type: C# file input

Write a method named MostCommon that accepts a string parameter representing a file name, then opens/reads that file's contents, and returns the word that occurs most frequently in the file. Words are separated by one or more spaces. Assume that any duplicate words will occur consecutively. If there is a tie, use the earlier word. You may assume that the string contains at least one word. For example, the following file's data will cause your method to return "Kim" because the word Kim occurs 3 times:

Ben Eric  Eric Marty Kim
Kim Kim  Jenny   Nancy
Nancy  Nancy  Paul   Paul
