Introduction of .Net Namespace

.Net Namespace: - Introduction

Namespaces are the way to organize .NET Framework Class Library into a logical grouping according to their functionality, usability as well as category. Namespaces are logical grouping of types for the purpose of easy identification.

The .NET Framework Class Library (FCL ) is a large collection of thousands of Classes. These Classes are organized in a hierarchical tree. The System Namespaces is the root for types in the .NET Framework.

We can uniquely identify any Class in the .NET Framework Class Library (FCL ) by using the full Namespaces of the class .In .Net language every program is created with a default Namespaces . Programmers can also create their own Namespaces in .Net languages.

The namespace which are created by the user is called user defined namespace. The namespace which are provided by the .NET is called predefined namespace.

The following are the some predefine namespace in .NET

1.       System:- The System namespace contains fundamental classes and base classes that define commonly-used value and reference data types, events and event handlers, interfaces, attributes, and exceptions classes.

2.       System.Configuration:- The System.Configuration namespaces contain types for handling configuration data, such as data in machine or application configuration files.

3.       System.Data:- The System.Data namespaces contain classes for accessing and managing data from different sources. This namespace contains the classes which are used to access data from the sql server,oracle and MS access database. The System.Data and its child namespace form the ADO.NET architecture.

4.       System.Diagnostics:- The System.Diagnostics namespaces contain classes that enable us to interact with system processes, event logs, and performance counters.

5.       System.Drawing:- The System.Drawing parent namespace contains classes that support basic GDI+ graphics functionality. Child namespaces support advanced two-dimensional and vector graphics functionality, advanced imaging functionality, and print- relatedservices.

6.       System.Globalization:- The System.Globalization namespace contains classes that define culture- related information, including language, country/region, calendars, and format patterns for dates and currency. These classes are useful for writing globalized (internationalized) applications.

7.       System.IO:- The System.IO namespaces contain classes that are used to perform the operations on the files and folder. System.IO namespace allow the user to read and write data from the files. This namespace allow the user to create a folder, delete a folder and many more operations on the folder.

8.       System.Net:- The System.Net namespaces contain classes that are used to create network based application in .NET. This Namespace provide a simple programming interface for a number of network protocols such as HTTP, TCP, IP etc which are used to programmatically access and update configuration settings of the Network.

9.       System.Security:- The System. Security namespaces contain classes that represent the .NET Framework security system and permissions. This namespace provides the classes for control access to objects, audit securable objects, allow authentication, provide cryptographic services, control access to resources and support rights management of application.

10.   System.Web:- The System. Web namespaces contain classes that allow the developer to create web based application. This namespace also provide the classes for data caching, HTTP handlers, incorporating AJAX functionality into ASP.NET and web services.

11. System.Windows:- The System.Windows namespaces contain the classes which are used in Windows Presentation Foundation (WPF) applications, including animation clients, user interface controls, data binding, and type conversion.  System.Windows.Forms and its child namespaces are used for developing Windows Forms applications.
