C# Beyond Basics

1. Additional Structures & File Handling

In this section we will learn data structures like Lists and Dictionaries. We will also learn how to read and write files. In the end we will look at how to deal with unexpected errors which can occur during the program's execution.

What are Lists?

Practicing List Declaration

List Methods

What are Dictionaries?

Practicing Dictionaries

Reading Files using StreamReader

Reading Files using File Methods

Writing Files

Error Handling

2. Structs & Enumerators

In this section we will learn about some more advanced structures for storing data, namely Structs and Enumerators. We will learn how to use them and we will look at some practice examples as well.

What are Structs?

Defining & Using a Structure

Practicing Structs

Structs with Other Data Structures

Struct Methods

Correctly Accessing Fields in Struct Methods

Practicing Methods

Struct Constructors

3. Introduction to Object-Oriented Programming (OOP)

In this section, we will learn what Object-Oriented Programming (OOP) is and how we can create programs that use the concept of OOP. We will also practice this concept with many hands-on tasks that are fun to solve.

What is Object-Oriented Programming?

Defining Classes

Practice: Creating Classes

Class Objects

Class Objects vs Struct Objects

Practice: Constructors

4. OOP Essentials

In this section, we delve deeper into the essentials of Object-Oriented Programming (OOP). We explore advanced topics to enhance your understanding and proficiency in OOP. From managing object lifecycles through destructors to refining class structures with access modifiers, and harnessing the power of derived classes and method overloading, this section equips you with the knowledge and practical skills needed to design robust and flexible object-oriented systems.

5. OOP Principles

This will be a detailed chapter in which we will dive deep into the main principles of Object-Oriented Programming (OOP). We will also look at many practical applications and hands-on examples of these principles to understand them better. In this section we will revise some of the concepts from the previous section in a bit more detail and combine the concepts together to understand it more thoroughly.

Structs with Other Data Structures

Since structs are essentially data types, we can use them for creating Arrays and Lists as well:

index.cs

In a List or an Array, we would access a Student object's field using the following syntax:

index.cs

For-example:

index.cs

We can also loop through these arrays or lists to assign or access data. For-example the following code loops through a List of Students objects and calculates the average age:

index.cs

It is clear that here the Student struct acts like a data type. We can also use Student as a dictionary value as well. Following is an example of using Struct as a value in a dictionary:

index.cs
