My Student Project: C# for Beginners: Assignment #4 (Series)

Permission to publish my code submitted for the project assignment was granted by the professor.

This is a very simple windows form application that I completed for a class assignment. It is shown here to illustrate my coding style, structure, and commenting. This example is considered Level 1 – Easy.


The main objectives of this assignment are:

• To learn using one-dimensional arrays.

• To learn how to write and use properties to access values saved in the private fields of an object.
In addition, exercise more with strings and also learn to use a ListBox for display of results. Keep the presentation of data (interaction with the user, input/output) from the logic behind data processing.


Apu (a user) is often asked to manage and organize parties. He would like to have a simple application that lists the names of the people to be invited to a party and also get an idea of the total cost based on an estimated cost per guest. We use a form object (MainForm) for the GUI and a class Party to contain the logic pertaining to party arrangements. For saving the names of the guests, use a one-dimensional array of strings in the Party class. MainForm declares a variable of the Party class as its field. We refer to this object as a party (with a small p).

MainForm should handle all the interactions (input/output) between the user and the application, and it should not contain logic that is (or can be) a part of the Party class’ responsibility. Every logic concerning the party, except processing of input and display of output, should be coded in the Party class.
