C# two class application that has as a data member an array that can store state area codes. Class should have member method that lets users enter an area code to see if its in the state exchange. member method should use one of the predifined methods of Array class and return true if the argument to the method is one of the state codes. Override the ToString() method to return the full list of areacodes with each surrounded by parentheses. To test class, store a list of state codes in a one-dimensional array. Send that array as an argumant to the class constructor. Test instance methods. The application should work with both an ordered and unordered list of area codes.

HELP!! Anyone ever had to write one like this? I have no clue where to start.
