C# -- Introduction to .NET Framework

C# - Chapter - 2

Introduction to .NET Framework

.NET Framework :-

• .NET Framework is a platform introduced by Microsoft to develop, host, deploy, maintain and execute applications.
• Applications can be

1. Console based
2. Windows based
3. Web based
4. Data Centric
5. Components
6. Web Services and so on

.NET framework is an entirely new environment for building internet-aware applications with a simplified deployment model. Different types of applications like Web Based, Windows based, data centric, Very rich GUI applications using Windows Presentation Foundation(WPF), web services and so on can be created. Moreover, these applications can be executed on any platform.

Microsoft Provides a platform or an environment to develop, host, deploy, maintain and execute applications. This environment or Platform is called .NET framework. Application can be of any type console based, window based, web based, data centric , components or a web service that can be used by any other application in a language neutral and platform independent manner.

.NET framework is a completely new model for building applications on windows family of operating systems as well as non-Microsoft Operating systems such as Mac OS and Linux/Unix.

Components of .NET Framework :-

.NET Framework consists of different components. Each component provides specific functionality.

.NET compatibility languages :-

• A Language is required to create any application. Using .NET, applications can be developed using languages such as C#, VB.NET, J#, and so on. More than 25 languages are supported by .NET Framework.

Common Language Runtime(CLR) :- 

• As mentioned earlier, different types of applications can be created using .NET framework. These applications need to be executed on any device. One of the main components of .NET - Common Language Runtime(CLR) executes the applications. So, CLR is known also Known as the execution engine or heart of .NET framework.

Framework Class Library(FCL):- 

• An application uses services in the form of components from other sources or functionality from a library. Another important components of .NET is framework class library(FCL). It also consists of classes that all applications can use to develop user interface, web pages or access  database. It also contains core classes which provide basic functionality like I/O, Security, Collections, XML support , multithreading etc.

Common Language Specification(CLS) :-

• The .NET Languages have to follow some rules. These rules are defined in Common Language Specification(CLS). If the language compilers follow these rules, the language are .NET compatible languages and their compilers are called as CLS-compliant compilers. Using CLS, third party language developers can design / redesign their language syntax as per .NET framework requirement.

Common Type System(CTS) :-

• As all the languages follow the same set of rules, code written in one language can be used by the code written in another language. This is Possible because of Common Type System (CTS). It defines common data types so that the code becomes interoperable.
• Applications can be created by using some IDE(Integrated Development Environment). This is not a part of Framework.

Microsoft Visual Studio.NET :-

• .NET applications can be easily created using Visual Studio integrated Developer Enviroment(IDE) tool. Visual Studio.NET provides in built application templates and tools for building .NET applications rapidly.

This is Just a Part of Chapter 2 Introduction to .NET framework, in next post i will update about remaining things in this chapter.

Object Oriented Programming Concepts

Object Oriented Programming Concepts

Object :-
             
What is Object ?

• Simply, An Object is an entity which has a well defined structure and behaviour.
• An object possesses certain characteristics as:

1. State
2. Behavior
3. Identity
4. Responsibility

--> Everything in this world is an object, from a nail to hammer, from a bus to Air-plane. From human perspective, an object is a tangible or visible thing or something that exists in time and space.

Object Can be defined as:

"An object represents an individual, Identifiable item, unit or entity, either real or abstract, with a well-defined role in the problem domain i.e., object has Identity, state, Behavior, and Responsibility."

Example: A car, a person, etc are different objects.

1.State of an Object :-

• The State of an Object includes the current values of all its attributes.
• An Attribute can be static or dynamic

For example, Employee Attributes

                       1.empID 

                       2.name

                       3.gender

above three attributes are Static Attributes.
                       4.age

                       5.address

                       6.phone

                       7.basicsal

                       8.education

                       9.experience

remaining these and all are Dynamic Attributes of an Employee .

2. Behavior of an Object :-

• Behavior is how an object acts and reacts, in terms of its state changes and message passing.
• Behavior of an object corresponds to its functions. The change in state of an Object reflects in its behavior.

For example, "calculate salary" and ''Print Details " are the behaviors of the employee. There can be other behaviors too. They can either help to retrieve the information or change the state of the attributes.

3. Identity of an Object :-

• Identity is that property of an object which distinguishes it from all other objects.
• A single or a group of attributes can be identify of an object.
• Every object existing in this world can be distinguished from the other. In other words, every object has its own identity.

4. Responsibility of an Object :-

• Responsibility of an object is the role it serves within the system. 

Some Important Points to remember about OBJECT

• Every Object has a state, behavior, responsibility, and unique identity.
• A system comprises of multiple objects existing together in a meaningful interaction.
• This meaningful interaction in the given system decides the responsibility of that object in that system.
• The Responsibility of an object decides the behavior of that object.
• The behavior of an object is governed by the change in state of that object.
• For changing the state of particular object, it is essential to identify it separately from all the other objects.

Polymorphism - Programming Code

Simple Programming Codes 

Polymorphism - Programming Code :-

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace polymorphism

{

    class Employee

    {

        public string FirstName = "FN";

        public string LastName = "LN";

        public virtual void PrintFullName()

        {

            Console.WriteLine(FirstName + " " + LastName);

        }

    }

    class FullTimeEmployee : Employee

    {

        public override void PrintFullName()

        {

            Console.WriteLine(FirstName + " " + LastName + "-Full Time Employee");

        }

    }

    class PartTimeEmployee : Employee

    {

        public override void PrintFullName()

        {

            Console.WriteLine(FirstName + " " + LastName + "-Part Time Employee");

        }

    }

    class TemporaryEmployee : Employee

    {

    }

    class Program

    {

        static void Main(string[] args)

        {

            Employee[] emp = new Employee[4];

            emp[0] = new Employee();

            emp[1] = new FullTimeEmployee();

            emp[2] = new PartTimeEmployee();

            emp[3] = new TemporaryEmployee();

            foreach (Employee e in emp)

            {

                e.PrintFullName();

            }

        }

    }

}

then output will be like :
FN LN
FN LN - Full Time Employee

FN LN - Part Time Employee

FN LN


*** This is very simple codenext i will post again Polymorphism Program code,            Thank you... ***

C# OOP(Object Oriented Programming) Concepts

Object Oriented Programming Concepts

The Key Concepts of Object Oriented Programming are :

•  Abstraction
•  Encapsulation
•  Inheritance
•  Polymorphism

Concept & Feature : 

• Concept : Abstraction
  Feature : Natural mapping and association of data and programs or sub-programs   which operate on that data.
• Concept : Encapsulation
  Feature : Hide or Unhide part of the data or Functionality from some components
• Concept : Inheritance
  Feature : Extend the functionality for new requirements without disturbing the existing implementation.

==> Difference between Object oriented & Object Based Languages

Object oriented Languages : All programming languages that support abstraction, encapsulation, inheritance and polymorphism are known as Object-Oriented.

Object Based Languages : All programming Languages that support abstraction and encapsulation but do not support inheritance, therefore cannot support polymorphism are known as object based languages. VB and Ada are are Object-Based languages.

What is an Object ?

• An object is an entity which has a well defined structure and behavior.
• An Object Possesses certain Characteristics are:
  ==> State
  ==> Behavior
  ==> Identity
  ==> Responsibility

Abstraction :

•  Abstraction is the Process of identifying the key aspects of an entity and ignoring the rest.
• Only those aspects are selected that are important to the current problem scenario.

Encapsulation :

• Encapsulation is a mechanism used to hide the data, internal structure, and implementation details of an object.
• All interaction with the object is through a public interface of operations.
• The user knows only about the interface, any changes to the implementation does not affect the user.

Inheritance :

• The Process of acquiring the Properties of Base class (Parent Class) to the Sub Class (Child Class) is known as Inheritance.
•  Inheritance is  " is - a " a kind of hierarchy.

Polymorphism : 

• The ability of different types of related objects to respond to the same message in their own ways is called polymorphism. 
• Polymorphism helps us to design extensible software, as new objects can be added to the design without rewriting existing procedures.
• Polymorphism is the ability to take more than one form. This means that one command may invoke different implementation for different related objects.

Capgemini Interview questions and answers

Questions and Answers for Capgmini Technical Round

1 ) What is OOP (Object Oriented Programming) ?--> OOP is a Programming paradigm  that represents concepts as "Objects" that have data fields (attributes that describes the Object) and associated procedures known as methods.
Objects, usually instances of Classes are used to interact with one another to design applicationsand computer Programs.
Some of OOP Laguages are C++, Objective-C, Small talk, Java, C#, Perl, Python, Ruby and PHP. 
           

2 ) What is VIEW ?--> VIEW is a Virtual Table.
The View is the Parts of the application that handles the display of the data.
most often the views are created from the model data.

In SQL-->
A View contains Rows and Columns, just like a real table. The fields in a View are fields from one or more real tables in Database. We can add SQL functions WHERE and JOIN statements to a view and present the data as if the data were coming from one single table.

A VIEW always shows up to date data.The database engine recreates the data, using the VIEW's  SQL Statements. Every time a user queries q VIEW.

3 ) What is Object and Class ?
--> Object is Instance of a class through which we can access the methods of that class. "New" Keyword is used for creating an Object.
Class is like a Blue print.

Object is a real world entity. Every object has state, behaviour an and identity. They are classified by their common state and behaviour by defining classes.

Class is compared to a template or mould, out of which similar kind of objects are created. object is an instance of a class.

Syntax :

<access specifier> class <class name>
{
           field declarations with respective access specifiers
           Event / Property / method declaration
}
    
4 ) Difference between RDBMS and DBMS ?--> DBMS manages large quantity of structured data with the advantages of query processing, controlling the access to data, data sharing and proper retrieval as well as modification of data.
RDBMS is a DBMS that stores the data in tables, a table is a collection of interrelated data entries and consists of columns and rows. Each of these tables has a unique identifier or "primary key". RDBMS also stores the relationship among the data in the form of tables.

Simply, In DBMS we can tables that can contain data. but, In RDBMS the tables have relationship.

5 ) What is PostBack ?--> PostBack is the name given to the process of submitting an ASP.NET page to the server for processing. PostBack is done if certain credentials of the page are to be checked against some sources (such as verification of username and password using database). This is something that a client machine is not able to accomplish and thus these details have to be 'posted back' to the server.
6 ) What is difference between Windows Application and Web Application ?
--> window 

7 ) What are the Class Access Modifiers ?---> Public, Static and Void are the Class Access Modifiers.

8 ) What is an Assembly ?---> An assembly is a collection of types and resources that forms a logical unit of functionality.
 
When you compile an application, the MSIL code created is stored in an assembly . 
Assemblies include both executable application files that you can run directly from Windows without the need for any other programs (these have a .exe file extension), and libraries (which have a .dll extension) for use by other applications.
 
There are two kind of assemblies in .NET :i) Private Assembly.
ii) Shared Assembly.

9 ) What is Serialization ?--> Serialization is the process of converting an object into a stream of Bytes.

When we want to transport an object through a network, then we have to convert the object into a stream of bytes. The process of converting an object into a stream of Bytes is called Serialization. For an object to be serialize, it should inherit ISerialize Interface. De-Serialization is the reverse process of creating an object from a stream of Bytes.

10) Difference between Clone() and Copy() ?--> Using clone() we can creates a new array object containing all the elements in the original array and using copy() method, all the elements of existing array copies into another existing array. Both methods perform Shallow copy.

11) What is Reflection ?--> Reflection is ability to examine the metadata in the assembly manifest at runtime.

reflection is technique provided for developers to examine the metadata at runtime. The ability to examine the metadata in the assembly manifest at runtime is known as reflection. It is used to dynamically create an instance of a type, bind the type to an existing object, or get the type from an existing object and invoke its methods or access its fields and properties.
  

12) Write a simple Program for Object()--> syntax for object

class Date             // this is class program
{
       public int day;
       public int month;
       public int year;
     
       public void PrintDate()       // this is method
       {
            Console.WriteLine("Date is :"+ day + " " + month + " " + year);
       }
}
class program
{
      static void main (string[] args)
      {
           Date d1 = new Date();              // object intialization
           d1.day = 26;
           d1.month = 1;
           d1.year = 2014;
           d1.PrintDate();
        }
}
