C# Tutorial (C Sharp)

Introduction to C#

C# (pronounced “C-Sharp”) is a modern, object-oriented, and versatile programming language developed by Microsoft in 2000 as part of its .NET initiative. It is designed to build a wide range of applications, from simple desktop programs to complex web applications, mobile apps, and enterprise software solutions.

Why Learn C#?

  1. Ease of Learning: C# has a syntax similar to other popular languages like C++, Java, and Python, making it beginner-friendly and easy to grasp.
  2. Versatility: You can create applications for Windows, macOS, Linux, Android, iOS, and even game development with Unity using C#.
  3. Powerful Framework: C# works seamlessly with the .NET Framework and .NET Core (now .NET 5 and beyond), providing access to a rich library of pre-built tools and functions.
  4. Popularity in Industry: C# is widely used in enterprise-level development, especially for creating Windows-based applications, server-side web apps, and games.

Key Features of C#

  • Object-Oriented Programming (OOP): C# supports OOP concepts like inheritance, polymorphism, encapsulation, and abstraction.
  • Type Safety: It prevents accidental data type errors, making the code more reliable.
  • Garbage Collection: C# handles memory management automatically, reducing memory leaks and improving performance.
  • Rich Library Support: With the .NET framework, you can leverage a vast collection of libraries for almost every development need.
  • Cross-Platform Development: With .NET Core and .NET 5+, C# supports development across multiple platforms.
  • Asynchronous Programming: C# provides built-in support for async programming with the async and await keywords, enhancing performance for IO-bound operations.

What Can You Build with C#?

  • Desktop Applications: Build powerful applications for Windows using frameworks like WPF (Windows Presentation Foundation) and WinForms.
  • Web Applications: Use ASP.NET or ASP.NET Core to create dynamic and scalable web applications.
  • Mobile Apps: Develop cross-platform mobile apps using Xamarin or .NET MAUI.
  • Game Development: Create stunning 2D and 3D games with Unity, one of the most popular game engines.
  • Cloud Applications: Build scalable cloud services and APIs with Azure.

Example: “Hello, World!” in C#

Here’s how a simple program looks in C#:

using System;

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