C# - Classes and Objects Questions and Answers
Understanding Classes and Objects in C# is a core concept for anyone preparing for software development interviews. These programming questions and answers explore how object-oriented programming (OOP) principles like encapsulation, abstraction, and inheritance are applied in C#. You’ll learn how classes define structure and behavior, while objects represent real-world entities within programs. Such C# programming MCQs and interview questions are commonly asked in TCS, Accenture, Wipro, and Infosys technical rounds. Practicing these C# OOP questions with explanations improves coding efficiency and conceptual clarity, making it easier to crack programming assessments and placement tests. Start now with C# Classes and Objects questions with answers to strengthen your fundamentals.
