C# Online Compiler: Code, Compile, and Debug C# Online

Introduction to C#

C# (pronounced "C-Sharp") is a modern, object-oriented programming language developed by Microsoft in the early 2000s. Designed to work seamlessly with the .NET framework, C# combines the power of C++ with the simplicity of modern programming languages, making it one of the most versatile tools for software development. From building enterprise-grade applications to game development and cloud solutions, C# is widely used across industries.

History of C#

• Origins and Development: C# was created in 2000 by Anders Hejlsberg as part of Microsoft’s .NET initiative. Its design was inspired by languages like C++, Java, and Delphi.
• Integration with .NET Framework: The language was developed to work specifically with the .NET framework, enabling developers to create scalable, secure, and high-performance applications.
• Standardization: C# was standardized by ECMA in 2002 and later by ISO, ensuring its global acceptance and consistency across implementations.
• Continuous Evolution: Over the years, C# has seen multiple updates, introducing features like LINQ, async/await, pattern matching, and records to enhance its capabilities.

What Kind of Language is C#?

• Object-Oriented: C# is built on the principles of object-oriented programming (OOP), making it easy to model real-world scenarios in code.
• Type-Safe: It ensures strict type-checking at compile time to prevent runtime errors.
• Platform-Independent with .NET Core: Although it was originally Windows-centric, .NET Core and .NET 5+ have made C# cross-platform.
• Compiled Language: C# is compiled into Intermediate Language (IL) by the .NET runtime, making it efficient and portable.

Key Features of C#

• Modern and Flexible: Combines simplicity with advanced features like async programming, delegates, and generics.
• Rich Library Support: Provides access to the .NET framework libraries for rapid development.
• Cross-Platform Development: Enables building applications for Windows, macOS, Linux, and even mobile platforms using Xamarin.
• Garbage Collection: Automatic memory management through garbage collection simplifies development.
• Interoperability: Easily interacts with other languages and technologies, including C++ and COM.
• Security: Built-in features like code access security and type safety ensure robust and secure applications.

Why Learn C#?

• Widely Used in the Industry: Essential for building Windows applications, enterprise software, games (via Unity), and cloud services (via Azure).
• Versatility: Supports desktop, web, mobile, and game development.
• Career Opportunities: Opens doors to roles like software engineer, game developer, and backend developer.
• Beginner-Friendly: With its clear syntax and extensive documentation, it’s an excellent choice for beginners.

Common Use Cases of C#

1. Enterprise Applications: Used to build secure and scalable business solutions.
2. Game Development: Widely used in the Unity game engine.
3. Web Development: Powers web applications through ASP.NET Core.
4. Cloud Computing: Essential for developing cloud solutions on Microsoft Azure.
5. Mobile Applications: Develops cross-platform mobile apps using Xamarin.

C# Syntax and Tutorial

Here’s a step-by-step guide covering important C# topics with examples:

1. Basic Syntax

using System; // Namespace for core functionalities

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

2. Variables and Data Types

C# is statically typed, so variables must be declared with a type.

int age = 25;               // Integer
double salary = 50000.50;   // Double
char grade = 'A';           // Character
string name = "Alice";      // String
bool isActive = true;       // Boolean

3. Control Structures

Conditional Statements

int score = 85;

if (score >= 90) {
    Console.WriteLine("Excellent");
} else if (score >= 75) {
    Console.WriteLine("Good");
} else {
    Console.WriteLine("Needs Improvement");
}

Loops

// For loop
for (int i = 0; i < 5; i++) {
    Console.WriteLine(i);
}

// While loop
int count = 0;
while (count < 5) {
    Console.WriteLine(count);
    count++;
}

// Do-while loop
do {
    Console.WriteLine(count);
    count--;
} while (count > 0);

4. Functions

class Calculator {
    static int Add(int a, int b) {
        return a + b;
    }

    static void Main(string[] args) {
        Console.WriteLine(Add(5, 10)); // Output: 15
    }
}

5. Object-Oriented Programming

Classes and Objects

class Car {
    public string Make { get; set; }
    public string Model { get; set; }

    public void Display() {
        Console.WriteLine($"{Make} {Model}");
    }
}

class Program {
    static void Main() {
        Car car = new Car { Make = "Toyota", Model = "Corolla" };
        car.Display();
    }
}

Inheritance

class Animal {
    public void Speak() {
        Console.WriteLine("Animal sound");
    }
}

class Dog : Animal {
    public void Bark() {
        Console.WriteLine("Woof");
    }
}

6. Advanced Topics

Asynchronous Programming

async Task FetchData() {
    await Task.Delay(2000); // Simulating delay
    Console.WriteLine("Data fetched");
}

LINQ

var numbers = new List<int> {1, 2, 3, 4, 5};
var evenNumbers = numbers.Where(n => n % 2 == 0).ToList();
