Encapsulation in C#

Encapsulation is the ability of an object oriented language (C# in this context) to hide unnecessary implementation details from the object user. Encapsulation makes coding simpler and helps to preserve data integrity.

According to the concept of encapsulation, an object’s internal data should not be directly accessible from an object instance. Members of a class that represent an object’s state should not be marked as public. The state of an object should only be altered indirectly by using public members. C# prefers properties to encapsulate data. Ex.

class ABC

{

// private data members

private int roll;

private int class;

private string name;

// public properties

public int Roll

{

get { return roll; }

set { roll = value; }

}

public int Class

{

get { return class; }

set { class = value; }

}

public string Name

{

get { return name; }

set { name = value; }

}

// constructor

public ABC()

{

// values are assigned to data members via properties

Roll = 10;

Class = 9;

Name = “Rajveer Raj Banti”;

}

}
