C # (Sharp)

Introduction to C# Programming

Course Description:

This course is designed to provide a comprehensive introduction to the C# programming language, one of the most widely used languages in software development, particularly for building Windows applications, games (using Unity), web services, and mobile apps. Students will learn how to write efficient, scalable, and maintainable code, understand object-oriented programming (OOP) principles, and gain hands-on experience with key libraries and frameworks in the .NET ecosystem.

Course Objectives:

By the end of this course, students will be able to:

Write basic and advanced C# programs.
Understand and implement object-oriented programming (OOP) concepts like classes, inheritance, and polymorphism.
Work with data types, collections, and LINQ for data manipulation.
Build simple applications such as calculators, file I/O programs, and basic web APIs.
Understand exception handling and debugging techniques.
Use Visual Studio or Visual Studio Code for writing and testing C# code.
Develop simple graphical user interface (GUI) applications using Windows Forms or WPF.
