What are some real-world examples of encapsulation in C#?

Encapsulation in C# is about bundling data and methods that operate on that data within a single unit. A real-world example is a class representing a bank account. The account balance is private, and methods like Deposit and Withdraw control access to it.

Can you explain how encapsulation improves code security?

Certainly! Encapsulation restricts direct access to some of an object's components, which helps prevent unintended interference and misuse. By exposing only necessary methods and properties, you can protect the integrity of the data.

Are there any other examples besides a bank account?

Yes! Another example is a car class. The internal state of the car, like engine status, can be private, while methods like StartEngine and StopEngine control access to that state.

How does encapsulation relate to data hiding?

Encapsulation is a key principle of data hiding. It allows you to hide the internal state of an object and only expose what is necessary, thus protecting the object's integrity and reducing complexity.

Can you give me a code snippet demonstrating encapsulation?

Sure! Here's a simple example:

public class BankAccount {
    private decimal balance;

    public void Deposit(decimal amount) {
        if (amount > 0) {
            balance += amount;
        }
    }

    public decimal GetBalance() {
        return balance;
    }
}

In this code, the balance is private, and can only be modified through the Deposit method.
