Structure of a C# Program

C# is a modern, object-oriented language created by Microsoft. It's used for game development (Unity), desktop applications, web and mobile. Let's look at the basic structure:

ðŸ’Ą Pro Tip

In C# 10+ you can use "top-level statements" and write code directly without the Program class. But it's good to understand the full structure first.

  • using System; - Imports the System namespace for basic functions
  • class Program - The class that contains our code
  • static void Main() - The entry point of the program
  • Console.WriteLine() - Displays text in the console
C#
using System;

class Program
{
    static void Main()
    {
        // Declare variables
        string name = "C#";
        int year = 2000;
        bool popular = true;
        
        // Display in console
        Console.WriteLine($"I'm learning {name}!");
        Console.WriteLine($"Released in {year}");
        Console.WriteLine($"Popular: {popular}");
    }
}
⚠ïļ Important

C# uses $"..." for string interpolation - much easier than concatenation with +!

Classes and Objects - The Foundation of OOP

C# is an OOP language. Everything revolves around classes and objects:

C#
class Player
{
    // Properties
    public string Name { get; set; }
    public int Health { get; set; }
    public int Score { get; private set; }
    
    // Constructor
    public Player(string name)
    {
        Name = name;
        Health = 100;
        Score = 0;
    }
    
    // Method
    public void EarnPoints(int points)
    {
        Score += points;
        Console.WriteLine($"{Name} earned {points} points!");
    }
}

// Usage
var player = new Player("Hero");
player.EarnPoints(50);

Frequently Asked Questions

No! The course starts from absolute zero. If you have experience with another language (Java, C++, Python), you'll progress faster, but it's not required.
Yes! The course prepares you with all the C# concepts you need for Unity: classes, OOP, events, delegates, LINQ. The Unity intro module shows you how to make the transition.
It depends on the engine! Unity uses C#, and Unreal Engine uses C++. C# is easier to learn and Unity is more accessible for indie developers. For AAA games and maximum performance, C++ is preferred.
Visual Studio Community (free) is the best for C# and .NET. For smaller projects, VS Code with the C# extension works great. For Unity, you use the integrated editor.
The course is available in English to allow access for students from all over the world. It includes practical examples, quizzes and projects.
Yes! You have a 30-day guarantee. If you're not satisfied with the course, we'll refund your money in full, no questions asked.
