Word Counter, Starting out with Visual C# 2012 3rd Edition

Develop an application that includes a method that accepts a string as an argument and returns the number of words it contains. For instance, if the argument is "Four score and seven years ago," the method should return the number 6. The application should let the user enter a string, and then it should pass the string to the method. The number of words in the string should be displayed....the picture I have attached is how my instructor would like the program to look, although the example program seems to be wrong because when i typed "Four score and seven years ago" the number of words it returned was 5 when it should have be 6.

Programa 1 Enter a string: four score and seven years ago Number of words 5 Count Words
