What are the different methods present in Socket Class?

Posted By :Srikanth     Posted Date :April 21, 2011    Points :40   Category :Networking 
There are 2 different type of methods present in Socket Class they are :

Synchronous Methods and Asynchronous Methods

In .Net Naming conventions all the ASynchronous Methods names are created by prefixing the words 'Begin' or 'End' to the names of Synchronous Methods

That is

Synchronous Methods :

(a) Connect()
(b) Receive()

ASynchronous Methods :

(a) BeginConnect() and EndConnect()
(b) BeginReceive() and EndReceive()

Why struct is not used to hold entity instead of class?

(eventhough struct provides us properties, methods and interface support)

Struct is a value type and
Class is a reference type.

Struct is stored in Stack - so if you pass a struct as argument to method - a new struct will be created on stack and values will be copied - this is a time consumingp process in the order of n.

Class is stored in Heap - so the same reference can be passed to various methods without duplication. (More...)

What are the different properties and methods of cache Class ?

Cahe Class ::

The Add/Insert method of the Cache class is used to add/insert an item into the cache. The Remove method removes a specified item from the cache. The Cache class contains the following properties and methods.


. Count
. Item


. Add
. Equals
. Get
. GetEnumerator
. GetHashCode
. GetType
. Insert
. Remove (Overloaded)
. ToString

What is a Socket Class?

Generally a Socket class provides a set of Synchronous and Asynchronous methods for the Synchronous and Asynchronous mode of communication.

We can get this using a name space called

System.Net.Sockets.Socket (More...)

Can an abstract class have non-abstract methods?

Yes an abstract class have non-abstract methods (More...)

What is the difference between the Clone() and Copy() methods of the DataSet class?

The Clone() method copies only the structure of a DataSet. The copied structure includes all the relation, constraint, and DataTable schemas used by the DataSet. The Clone() method does not copy the data, which is stored in the DataSet.

The Copy() method copies the structure as well as the data stored in the DataSet. (More...)

What is the difference between a Struct and a Class?

The struct type is suitable for representing lightweight objects such as Point, Rectangle, and Color. Although it is possible to represent a point as a class, a struct is more efficient in some scenarios. For example, if you declare an array of 1000 Point objects, you will allocate additional memory for referencing each object. In this case, the struct is less expensive.

When you create a struct object using the new operator, it gets created and the appropriate constructor is called. Unlike classes, structs can be instantiated without using the new operator. If you do not use new, the fields will remain unassigned and the object cannot be used until all of the fields are initialized.

It is an error to declare a default (parameterless) constructor for a struct. A default constructor is always provided to initialize the struct members to their default values.

It is an error to initialize an instance field in a struct.

There is no inheritance for structs as there is for classes. A struct cannot inherit from another struct or class, and it cannot be the base of a class. Structs, however, inherit from the base class Object. A struct can implement interfaces, and it does that exactly as classes do.

A struct is a value type, while a class is a reference type. (More...)

Can we call a base class method without creating instance?

Its possible If its a static method.

Its possible by inheriting from that class also.

Its possible from derived classes using base keyword. (More...)

What is Private Constructor? and it's use? Can you create instance of a class which has Private Constructor?

When a class declares only private instance constructors, it is not possible for classes outside the program to derive from the class or to directly create instances of it. (Except Nested classes)
Make a constructor private if:

1) You want it to be available only to the class itself. For example, you might have a special constructor used only in the implementation of your class' Clone method.

2) You do not want instances of your component to be created. For example, you may have a class containing nothing but Shared utility functions, and no instance data. Creating instances of the class would waste memory. (More...)
