3. Core Concepts Of C Sharp

Understanding the core concepts of C Sharp is crucial for writing effective and efficient code. Here are some fundamental concepts you should master.

3.1 Variables And Data Types

Variables are used to store data in a program. Each variable has a data type that specifies the kind of data it can hold.

Data Type	Description	Example
`int`	Represents a 32-bit integer.	`int age = 30;`
`double`	Represents a 64-bit floating-point number.	`double price = 19.99;`
`string`	Represents a sequence of characters.	`string name = "John";`
`bool`	Represents a boolean value (true or false).	`bool isTrue = true;`
`char`	Represents a single Unicode character.	`char grade = 'A';`
`decimal`	Represents a precise decimal value suitable for financial calculations.	`decimal salary = 50000.00m;`

3.2 Control Structures

Control structures determine the flow of execution in a program. They allow you to make decisions and repeat actions based on certain conditions.

3.2.1 Conditional Statements

If Statement: Executes a block of code if a condition is true.

if (age >= 18) {
    Console.WriteLine("You are an adult.");
}

If-Else Statement: Executes one block of code if a condition is true and another block if it is false.

if (age >= 18) {
    Console.WriteLine("You are an adult.");
} else {
    Console.WriteLine("You are a minor.");
}

Switch Statement: Executes different blocks of code based on the value of a variable.

switch (day) {
    case "Monday":
        Console.WriteLine("It's Monday.");
        break;
    case "Tuesday":
        Console.WriteLine("It's Tuesday.");
        break;
    default:
        Console.WriteLine("It's another day.");
        break;
}

3.2.2 Looping Statements

For Loop: Repeats a block of code a specific number of times.
```
for (int i = 0; i < 10; i++) {
    Console.WriteLine(i);
}
```

While Loop: Repeats a block of code as long as a condition is true.

int count = 0;
while (count < 10) {
    Console.WriteLine(count);
    count++;
}

Do-While Loop: Repeats a block of code at least once, and then continues as long as a condition is true.
```
int count = 0;
do {
    Console.WriteLine(count);
    count++;
} while (count < 10);
```

Foreach Loop: Iterates over elements in a collection (e.g., arrays, lists).

string[] names = {"Alice", "Bob", "Charlie"};
foreach (string name in names) {
    Console.WriteLine(name);
}

3.3 Object-Oriented Programming (OOP)

C Sharp is an object-oriented programming language, which means it is based on the concept of “objects,” which contain data and code:

Classes: Blueprints for creating objects.

class Dog {
    public string Breed { get; set; }
    public string Name { get; set; }

    public void Bark() {
        Console.WriteLine("Woof!");
    }
}

Objects: Instances of classes.

Dog myDog = new Dog();
myDog.Breed = "Golden Retriever";
myDog.Name = "Buddy";
myDog.Bark();

Inheritance: Allows a class to inherit properties and methods from another class.

class Animal {
    public string Name { get; set; }
    public virtual void MakeSound() {
        Console.WriteLine("Generic animal sound");
    }
}

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

Polymorphism: Allows objects of different classes to be treated as objects of a common type.
```
Animal myAnimal = new Dog();
myAnimal.MakeSound(); // Output: Woof!
```

Encapsulation: Bundling data and methods that operate on that data within a class, and protecting the data from outside access.

class BankAccount {
    private double balance;

    public void Deposit(double amount) {
        balance += amount;
    }

    public double GetBalance() {
        return balance;
    }
}

Abstraction: Hiding complex implementation details and showing only the essential features of an object.

4. Hands-On Practice: Writing Your First C Sharp Program

Theory is important, but practical experience is invaluable. Let’s walk through writing your first C Sharp program.

4.1 Creating A Simple “Hello, World!” Program

Open Your IDE: Launch Visual Studio, Visual Studio Code, or your preferred IDE.
Create A New Project:
- In Visual Studio, select “Create a new project.”
- Choose “Console App (.NET Framework)” or “Console App (.NET Core)” and click “Next.”
- Name your project (e.g., “HelloWorld”) and click “Create.”

Write The Code:

Open the Program.cs file.

Replace the existing code with the following:

using System;

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

Run The Program:
- In Visual Studio, press Ctrl + F5 to run the program without debugging.
- In Visual Studio Code, open the terminal (View > Terminal) and run dotnet run.
- You should see “Hello, World!” printed in the console.

4.2 Understanding The Code

using System;: Imports the System namespace, which contains basic classes and functionalities.
namespace HelloWorld: Declares a namespace for your program.
class Program: Defines a class named Program.
static void Main(string[] args): The main method, which is the entry point of the program.
Console.WriteLine("Hello, World!");: Prints “Hello, World!” to the console.

4.3 Modifying The Program

Try modifying the program to make it more interactive.

Add User Input:

using System;

namespace InteractiveProgram {
    class Program {
        static void Main(string[] args) {
            Console.WriteLine("What is your name?");
            string name = Console.ReadLine();
            Console.WriteLine("Hello, " + name + "!");
        }
    }
}

Run The Program:
- Run the program as before.
- The program will ask for your name, and after you enter it, it will greet you.

5. Advanced C Sharp Concepts

Once you have a solid grasp of the basics, you can move on to more advanced topics.

5.1 LINQ (Language Integrated Query)

LINQ allows you to query data from different sources (e.g., collections, databases, XML) using a unified syntax.

using System;
using System.Linq;

namespace LINQExample {
    class Program {
        static void Main(string[] args) {
            int[] numbers = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

            // Using LINQ to find even numbers
            var evenNumbers = from num in numbers
                              where num % 2 == 0
                              select num;

            foreach (int num in evenNumbers) {
                Console.WriteLine(num);
            }
        }
    }
}

5.2 Asynchronous Programming

Asynchronous programming allows you to perform multiple tasks concurrently without blocking the main thread, improving application responsiveness.

using System;
using System.Threading.Tasks;

namespace AsyncExample {
    class Program {
        static async Task Main(string[] args) {
            Console.WriteLine("Starting task...");
            await Task.Delay(3000); // Simulate a long-running task
            Console.WriteLine("Task completed!");
        }
    }
}

5.3 Delegates And Events

Delegates are type-safe function pointers, and events are a way for a class to notify other classes when something of interest happens.

using System;

namespace DelegateEventExample {
    // Define a delegate
    public delegate void MyDelegate(string message);

    class Program {
        // Method that matches the delegate signature
        public static void ShowMessage(string message) {
            Console.WriteLine("Message: " + message);
        }

        static void Main(string[] args) {
            // Create an instance of the delegate
            MyDelegate del = new MyDelegate(ShowMessage);

            // Call the delegate
            del("Hello from delegate!");
        }
    }
}

5.4 Generics

Generics allow you to write code that can work with different data types without being specific about those types at compile time.

using System;
using System.Collections.Generic;

namespace GenericsExample {
    // Generic class
    class DataStore<T> {
        private T data;

        public DataStore(T value) {
            data = value;
        }

        public T GetData() {
            return data;
        }
    }

    class Program {
        static void Main(string[] args) {
            // Create a DataStore for integers
            DataStore<int> intStore = new DataStore<int>(100);
            Console.WriteLine("Integer value: " + intStore.GetData());

            // Create a DataStore for strings
            DataStore<string> stringStore = new DataStore<string>("Hello Generics!");
            Console.WriteLine("String value: " + stringStore.GetData());
        }
    }
}
