C# - Difference between Initialization and Instantiation

Introduction:

Here I will explain difference between initialization and instantiation in c#, vb.net with example or instantiation vs initialization in asp.net or how to instantiate and initialize a class in asp.net using c#, vb.net with example. In c# or vb.net instantiation means declaring object for class and initialization means assigning values to variables or setting initial values.

Description:

In previous posts I explained cursor in sql server with example, oops concepts in c# with examples, difference between dispose vs finalize method, difference between pageload and page_init in asp.net, constructors in c#, vb.net, delegates in c# with example and many articles relating to interview questions, asp.net, c#.net. Now I will explain difference between instantiation and initialization in c#, vb.net with example.

Initialization

Initialization means assigning initial value to variables while declaring.

Example of Initialization

Following is the simple example of initialization in application.

int a;//Declaration   a = 10;//Initialization   or   int a = 10;

Instantiation

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

Example

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.

I hope it helps you to understand difference between initialization and instantiation.
