DotNet FrameWork – Resource Files – Dispose and Finallize method – encapsulation – What is inline schema, how does it work – Day 22 of 30

Whate are Resource Files ? How are they used in .NET?

Resource files are the files containing data that is logically deployed with an application.These files can contain data in a number of formats including strings, images and persisted objects. It has the main advantage of If we store data in these files then we don’t need to compile these if the data get changed. In .NET we basically require them storing culture specific informations by localizing application’s resources. You can deploy your resources using satellite assemblies.


Difference between Dispose and Finallize method?

Finalize method is used to free the memory used by some unmanaged resources like window handles (HWND). It’s similar to the destructor syntax in C#. The GC calls this method when it founds no more references to the object. But, In some cases we may need release the memory used by the resources explicitely.To release the memory explicitly we need to implement the Dispose method of IDisposable interface.


What is encapsulation ?

Encapsulation is the ability to hide the internal workings of an object’s behavior and its data. For instance, let’s say you have a object named Bike and this object has a method named start(). When you create an instance of a Bike object and call its start() method you are not worried about what happens to accomplish this, you just want to make sure the state of the bike is changed to ‘running’ afterwards. This kind of behavior hiding is encapsulation and it makes programming much easier.


How can you prevent your class to be inherated further?

By setting Sealed – Key word

public sealed class Planet {             //code goes here        }

class Moon:Planet {     //Not allowed as base class is sealed        }


What is GUID and why we need to use it and in what condition? How this is created.

A GUID is a 128-bit integer (16 bytes) that can be used across all computers and networks wherever  a unique identifier is required. Such an identifier has a very low probability of being duplicated. Visual Studio .NET IDE has a utility under the tools menu to generate GUIDs.

Why do you need to serialize.?

We need to serialize the object,if you want to pass object from one  computer/application domain to another.Process of converting complex objects into stream of bytes that can be persisted or  transported.Namespace for serialization is System.Runtime.Serialization.The  ISerializable interface allows you to make any class Serializable..NET framework features 2 serializing method.

1.Binary Serialization 2.XML Serialization


What is inline schema, how does it work?

Schemas can be included inside of XML file is called Inline Schemas.This is useful  when it is inconvenient to physically seprate the schema and the XML document.A  schema is an XML document that defines the structure, constraints, data types, and  relationships of the elements that constitute the data contained inside the XML  document or in another XML document.Schema can be an external file which uses the  XSD or XDR extension called external schema. Inline schema can take place even when validation is turned off.
