C# Introduction

Welcome to The Coding College! At thecodingcollege.com, we’re committed to delivering high-quality programming tutorials to help you excel in your coding journey. This guide provides an introduction to C#, one of the most versatile and popular programming languages.

What is C#?

C# (pronounced “C Sharp”) is a modern, object-oriented programming language developed by Microsoft as part of its .NET platform. Released in 2000, it is designed to be simple, safe, and scalable, making it an excellent choice for building:

  • Desktop applications
  • Web applications
  • Mobile applications
  • Game development (with Unity)

C# combines the power of C++ with the simplicity of Java, providing developers with a robust tool to create a wide range of applications.

Key Features of C#

  1. Object-Oriented
    C# supports object-oriented programming concepts like inheritance, polymorphism, encapsulation, and abstraction, which help in building modular and reusable code.
  2. Cross-Platform Development
    With .NET Core, C# enables developers to create cross-platform applications that run on Windows, macOS, and Linux.
  3. Type-Safe
    The language enforces strict type-checking, minimizing runtime errors.
  4. Rich Library Support
    C# provides access to a vast library within the .NET framework, simplifying development with pre-built classes and methods.
  5. Automatic Garbage Collection
    C# automatically manages memory allocation and cleanup, reducing the chances of memory leaks.

Why Learn C#?

  • In-Demand Skill: C# is widely used in industries like game development (Unity Engine), enterprise solutions, and cloud computing.
  • Versatility: From games to web APIs, C# is a go-to language for various applications.
  • Beginner-Friendly: Its simple syntax makes it easy to learn for beginners while being powerful for advanced developers.

How Does C# Work?

C# programs are built on the .NET framework, which provides:

  1. Common Language Runtime (CLR): Executes the code and provides services like memory management and exception handling.
  2. Base Class Library (BCL): A collection of reusable classes that simplify coding.

When you write a C# program, it is compiled into Intermediate Language (IL), which is then executed by the CLR.

The First Steps: Writing Your First C# Program

Here’s how to write your first “Hello, World!” program in C#:

using System;

class Program
{
    static void Main()
    {
        Console.WriteLine("Hello, World!");
    }
}

Explanation:

  • using System;: Includes the System namespace, which provides essential classes and methods.
  • class Program: Defines a class named Program.
  • static void Main(): The entry point of the program.
  • Console.WriteLine: Prints output to the console.

Applications of C#

  1. Game Development
    C# is the primary language used in Unity, one of the most popular game engines.
  2. Web Development
    Build dynamic websites using ASP.NET Core, a framework powered by C#.
  3. Desktop Applications
    C# supports Windows Forms and WPF for creating desktop applications.
  4. Mobile Development
    Xamarin allows developers to create cross-platform mobile applications using C#.
