In collections based on IList or directly on ICollection, every element contains only a value. These types include: 1. Array 2. ArrayList 3. List<T> 4. Queue 5. ConcurrentQueue<T> 6. Stack 7. ConcurrentStack<T> 8. LinkedList<T> In collections based on the IDictionary int...

An iterator can be used to step through collections such as lists and arrays. An iterator method uses the yield return statement to return each element one at a time. When a yield return statement is reached, the current location in code is remembered. Execution is restarted from that location the...

Lecture: - declare fields/variables as private - provide public get and set methods, through properties, to access and update the value of a private field class Person{ private string name; // field public string Name{ get; set; } // property } class Program { static void Main(string[] ...

Lecture Inheritance lets us inherit fields and methods from another class. Polymorphism uses those methods to perform different tasks. This allows us to perform a single action in different ways. Code Example class Animal // Base class (parent) { public void animalSound() { Console...

Virtual methods have an implementation and provide the derived classes with the option of overriding it. Abstract methods do not provide an implementation and force the derived classes to override the method. public abstract class E { public abstract void AbstractMethod(int i); public vi...

Polymorphism is often referred to as the third pillar of object-oriented programming, after encapsulation and inheritance. Virtual methods enable you to work with groups of related objects in a uniform way. For example, suppose you have a drawing application that enables a user to create various k...

Object Oriented programming organizes code by creating types in the form of classes. These classes contain the code that represents a specific entity. A class definition is like a blueprint that specifies what the type can do. The following list includes all the various kinds of members that may...

An interface defines a contract. Any class, record or struct that implements that contract must provide an implementation of the members defined in the interface. interface IPoint { // Property signatures: int X { get; set; } int Y { get; set; } double Distance { get; } } cla...
