Concept of Property with C#

Introduction

Property In C#

A property is an entity that describes the features of an object. A property is a piece of data contained within a class that has an exposed interface for reading/writing.

Main purpose

Properties are used to access our private class members and used them like a variables.
Properties are special kind of method or block which have two successors and this property cant take any arguments.
Properties are look like a variables.
Properties are used to security access our private class members.
Properties increase usability with maintaining security.

The two successor of Properties are "get" and "set"
get -- used to return the value.
set -- used to assign the value.

Syntax of Property

public returnType PropertyName
{
set { privateVariable = value;}
get { return privateVariable; }
}

Types of Properties

1) Read-Only (only get)
2) Write-Only(only set)
3) Normal (get & set both)

Program Read-Only

using System;
namespace property
{
class ReadOnlyProp
{
string name="DEEPAK DWIJ "; // private variable-bcoz ByDefault member variable of class is Private.
public string ROnly // Read only property only returns the private variable.
{
get { return name; }
}
}
class Program:ReadOnlyProp
{
public static void Main()
{
Program rdonly = new Program();
Console.WriteLine(rdonly.ROnly);
Console.Read();
}
}
}

Output

Program WriteOnly

using System;
namespace WriteOnly
{
class UseSet
{
private string name = string.Empty;
public string Wonly // ONLY SET PROPETY
{
set { name = value; }
}
public void DisplayData()
{
Console.WriteLine("Name: {0}",name);
}
}
class Program : UseSet
{
public static void Main(string[] args)
{
Program wrt = new Program();
wrt.Wonly = "DEEPAK SHARMA";
wrt.DisplayData();
Console.Read();
}
}
}

Output

Program Normal(set and get both)

using System;
namespace Deep
{
abstract class Car
{
string regno;
int modelno;
public int Model // This is property 1st
{
set { modelno = value; }
get { return modelno; }
}
public string Resgistration // This is property 2nd
{
set { regno = value; }
get { return regno; }
}
public void brakes() // function
{
Console.WriteLine("Brakes are important to drive safely");
}
}
class Maruti:Car
{
public static void Main()
{
Maruti mr = new Maruti();
Console.WriteLine(" Maruti CAR DESCRIPTION");
Console.WriteLine("*******************************************");
mr.Model = 2005;
mr.Resgistration = "UP-14 Z 6224-DEEPAK";
Console.WriteLine("CarModel : " + mr.Model + "");
Console.WriteLine("CarRegistration : " + mr.Resgistration + "");
mr.brakes();
Console.WriteLine("*******************************************");
Console.Read();
}
}
}
