Hello @Babuddin Encapsulation is defined 'as the process of enclosing one or more items within a physical or logical package'. Encapsulation, in object oriented programming methodology, prevents access to implementation details. Encapsulation is implemented by using access specifiers . An access specifier defines the scope and visibility of a class member. C# supports the following access specifiers: Public Private Protected Internal Protected internal For More detail you can refer this link http://www.tutorialspoint.com/csharp/csharp_encapsulation.htm

Hi, In simple words, Encapsulation is the packing of data and functions into a single component. The features of encapsulation are supported using classes in most object-oriented programming languages, although other alternatives also exist. Important points Through encapsulation a class can hide the internal details of how an object does something. Encapsulation solves the problem at the implementation level. A class or structure can specify how accessible each of its members (variables, properties, and methods) is to code outside of the class or structure. Encapsulation simplifies the interaction between objects. An object can use another object without knowing all its data or how its data is maintained. For example, a Client object might have name, address, company, and department properties. If a Bank object wants to use a Client object, it can request the name and address for the bank without needing to know the company and department details of the Client object. With the help of encapsulation, a class can change the internal implementation without hurting the overall functionality of the system. Encapsulation protects abstraction. Need or purpose of encapsulation To hide and prevent code (data) from the outside world (here the world means other classes and assemblies). To prevent code (data) from accidental corruption due to programming errors so that we can deliver expected output. Due to programming mistakes, code may not behave properly and it has an effect on data and then it will affect the functionality of the system. With encapsulation we can make variables, properties, and methods private so it is not accessible to all but accessible through proper channels only to protect it from accidental corruption from other classes. To have a class better control over its fields (validating values etc…).
