C# - Difference between Instantiation and Inheriting (Inheritance) a Class

Introduction:

Here I will explain difference between instantiation and inheriting (inheritance) a class in c#, vb.net with example or instantiation vs inheritance in asp.net or how to instantiate and inherit a class in asp.net using c#, vb.net with example. In c# or vb.net instantiation means declaring object for class and inheritance means acquiring properties from base class.

Description:

In previous posts I explained @@IDENTITY vs SCOPE_IDENTITY () vs IDENT_CURRENT, difference between dispose and finalize method in c#, authorization in asp.net, difference between page_init and page_load events in asp.net, difference between ref and out parameters in c#, delegates in c# with example and many articles relating to interview questions, asp.net, c#.net. Now I will explain difference between instantiation and inheritance in c#, vb.net with example.

Inheritance

Inheritance means it’s a kind of relation between two classes like parent and child. In inheritance child class will acquire all properties from parent class like methods, events, nested types of parent class, operators and fields.

Example of using Inheritance

Following is the simple example of defining inheritance in classes.

// Parent Class class parent { // your code }; // Child Class class child : parent { // child class will inherit all properties from parent class }

Instantiation

Instantiation means defining or creating new object for class to access all properties like methods, operators, fields, etc. from class.

Example if Instantiation

Following is the example of defining instantiation in application.

class sampleclass { // your code } class Program { static void Main() { // Instantiating sampleclass sampleclass sobj = new sampleclass(); } }

If you observe above syntax we created new object by instantiating sampleclass class. By using new object sobj we can access all the methods and properties from sampleclass class.
