What is encapsulation in C#?

Can you explain what encapsulation is in C#?

Sure! Encapsulation is a fundamental concept in object-oriented programming that restricts access to certain components of an object. In C#, it allows you to bundle the data (attributes) and methods (functions) that operate on the data into a single unit, or class, while controlling access to the inner workings of that class.

Why is encapsulation important in programming?

Encapsulation is important because it helps to protect the integrity of the object's data by preventing external interference and misuse. It also promotes modularity and maintainability, making it easier to manage and update code.

Can you give me an example of encapsulation in C#?

Certainly! 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 example, the balance field is private, so it can't be accessed directly from outside the class. Instead, you use the Deposit method to modify it and GetBalance to retrieve its value.

What are the benefits of using encapsulation?

The benefits of encapsulation include improved data security, easier debugging, and the ability to change the internal implementation without affecting external code that uses the class.
