C#Tutorial-CSHARP

1. Introduction to C# (C Sharp) Welcome to this presentation on C#, Microsoft's versatile programming language. We'll explore its features and applications, from web development to game creation. C# continues to evolve, empowering developers to build robust, high-performance applications. BY Rishabh parmar https://www.tpointtech.com/c-sharp-tutorial 9599086977

2. Getting Started: Setup & First Program Install Tools Install .NET SDK 8.0+ and Visual Studio Code. Create Project Use `dotnet new console` to set up your app. Write Code Add `Console.WriteLine("Hello, C# World!");` to Program.cs. Execute Program Run your application from the terminal with `dotnet run`. C#

3. Fundamental Concepts: Variables & Data Types Value Types Reference Types Directly store data. Examples include `int` for numbers, `double` for decimals, and `bool` for true/false. Store references to data. Examples are `string` for text and `object` for complex structures. • int age = 30; • string name = "Alice"; • double price = 19.99; Strongly Typed • bool isActive = true; C# requires explicit variable type declaration. • var count = 100; C#

4. Control Flow: Decisions & Loops Conditional Statements Execute code based on specific conditions. Use `if`/`else if`/`else` for branching logic. The `switch` statement handles multiple options efficiently. if (score >= 90) Console.WriteLine("A"); Looping Constructs Repeat code execution. The `for` loop is ideal for known iterations. `while` and `do-while` loops continue based on conditions. `foreach` simplifies collection iteration. for (int i = 0; i < 5; i++) C#

5. Object-Oriented Programming (OOP): Classes & Objects Classes: The Blueprints Objects: Instances A class defines properties (data) and methods (behaviors) for objects. Think of it as a template. An object is a concrete instance of a class. You create objects from classes, then interact with their properties and methods. public class Car { public string Color { get; set; } public void StartEngine() { }} Car myCar = new Car();myCar.Color = "Blue";myCar.StartEngine(); C#

6. OOP Principles: Inheritance & Polymorphism Inheritance Polymorphism Classes can inherit features from other classes. This creates an "is-a" relationship, like a SportsCar is a Car. Objects can take on many forms. This allows different types of objects to be treated as a common type. • Method Overriding public class SportsCar : Car { } • Interface Implementation C#

7. Modern C# Features: LINQ & Asynchronous Programming LINQ (Language Integrated Query) Query data from various sources using SQL-like syntax directly in C# code. This simplifies data manipulation. var evens = numbers.Where(n => n % 2 == 0).ToList(); Asynchronous Programming (Async/Await) Perform I/O operations without freezing your application. Improves responsiveness, crucial for modern applications. var data = await httpClient.GetStringAsync(url); C#
