Understanding Classes and Objects in C#

Every robust C# application relies on object-oriented principles, where classes serve as the fundamental blueprints for creating objects. Understanding how to structure these blueprints is the single most important step in transitioning from writing simple scripts to building scalable software. This text-based course guides you through the core mechanics of object creation, data encapsulation, and modern C# development practices. You will start with foundational definitions, learning how to define properties, methods, and constructors before moving on to real-world applications. By reading through clear explanations and structured code examples, you will gain a practical mental model of how objects interact in memory. What you'll learn: - Understand the foundational theory of object-oriented programming and how classes act as templates. - Define class members including properties, auto-implemented properties, fields, and methods. - Configure constructors to initialize objects with valid state and explore modern object initializers. - Apply encapsulation principles using access modifiers to protect internal object state. - Practice modern C# features such as Nullable reference types and basic record types for immutable data. - Analyze how objects are allocated in memory to write efficient, leak-free code. The course begins with essential terminology and syntax before progressively walking you through class design, instantiation, and object communication. It is designed specifically for beginners with basic programming knowledge who want to establish a rock-solid foundation in modern C# development.
