Classes and Objects in C#

Understanding classes and objects is essential for mastering object-oriented programming in C#. Let’s dive into the core concepts:

 

Class – The Blueprint

A class is a template that defines the properties (fields) and behaviors (methods) of an object. It does not hold any data itself but sets the structure for creating objects.

Example:

class Car

{

    public string Model;

    public int Year;

 

    public void Drive()

    {

        Console.WriteLine("Driving the car");

    }

}

  • Model, Year – Properties
  • Drive() – Method (behavior)

 

Object – The Real Instance

An object is a specific instance of a class. It holds actual values and can use the class’s methods.

Example:

Car myCar = new Car();

myCar.Model = "Toyota";

myCar.Year = 2022;

myCar.Drive(); // Output: Driving the car

  • myCar is an object created from the Car class.
  • It uses and stores real values ("Toyota", 2022).
  • It calls the method Drive() defined in the class.

 

By mastering classes and objects, you're building a strong foundation in object-oriented design, making your code modular, reusable, and scalable.

Promises in Angular

-
Promises in Angular In Angular,  Promises  provide a mechanism for handling  asynchronous operations  that resolve a  single value  or an  error  in the future. They are ideal for tasks that complete once, such as API calls or timers. Key Features of Promises Promises resolve only once—either with a success value (resolve) or an error (reject). They do not support multiple emissions like Observables. Promises begin executing  immediately  when they are created. They are not lazy and cannot be deferred like Observables. Once a Promise starts, it  cannot be cancelled . This limits their flexibility in situations where you may want to abort the operation. Promises work seamlessly with async/await, making asynchronous code easier to write and understand. Typical Use Cases ·       One-time data fetching ·     ...

Mastering Your Angular Workflow: Essential CLI Commands for Efficient Development

-
Mastering Your Angular Workflow: Essential CLI Commands for Efficient Development The Angular CLI (Command Line Interface) is a cornerstone of modern Angular development. It streamlines project setup, code generation, testing, and deployment, empowering developers to focus on building maintainable and scalable applications. This guide covers the most essential Angular CLI commands to help you optimize your workflow from project creation to deployment and beyond.   1. Creating a New Angular Project Use the ng new command to initialize a new Angular workspace. Example: Create a standalone app with SCSS and routing (without Server-Side Rendering): ng new PracticeAngular --routing --standalone --style=scss --no-ssr Flag Breakdown: --routing: Sets up Angular Router. --standalone: Uses standalone components (no NgModules). --style=scss: Uses SCSS for styling. --no-ssr: Skips Server-Side Rendering setup.   2. Accessing CLI Help The CLI includes built-...

Observables in Angular

-
Observables in Angular In Angular,  Observables  are a foundational mechanism for managing asynchronous data streams and event handling. They offer a powerful, flexible way to react to changing data over time.   Key Features of Observables Unlike Promises that emit a single value, Observables can emit multiple values over time — ideal for continuous streams like user input, live data, or WebSockets. Observables are lazy — they only start emitting values when explicitly subscribed to. This improves performance and avoids unnecessary computation. You can unsubscribe from an Observable using .unsubscribe() to clean up resources and prevent memory leaks. Observables leverage the  RxJS  library, which provides a rich set of operators like: map, filter, debounceTime, mergeMap, etc. These enable powerful, declarative transformations and compositions of data streams. Observables are deeply embedded...
