Learn How to Structure Applications with C# and .NET

In the Programmer Analyst – LEA.9C Program at CDI College, object-oriented programming is a key part of learning how to build applications with a structured approach using C# and .NET. This model organizes code around classes, objects, and interfaces, making solutions more transparent, more consistent, and easier to maintain over time.

Understand the Foundations of Object-Oriented Programming

The program starts with core elements of object-oriented programming, including variables, constants, operators, and control structures. Students also learn how to write functions, manage errors, and document their work.

This section emphasizes essential programming habits, including compiling, debugging, and validating results through structured testing.

Work with Classes, Interfaces, and Inheritance

Students then develop more advanced object-oriented skills, including:

• creating and organizing classes and interfaces;
• applying encapsulation, polymorphism, and inheritance;
• designing solutions that are easier to evolve and maintain.

These concepts support more robust application development and strengthen understanding of software structure.

Design Applications and User Interfaces

Course content also includes working with a code library to build management applications with richer graphical interfaces, as well as user interface design concepts.
These elements are approached from a software development perspective to improve application clarity and usability.

The goal is to help students build a consistent method for creating, improving, and maintaining applications.

A Key Skill for Integration Projects

Object-oriented programming supports other parts of the program, especially the integration projects. By mastering these concepts, students strengthen their ability to analyze requirements, structure solutions, and write cleaner, more maintainable code.
