VB.NET:An introduction to Namespaces in .NET framework

What is Namespace in VB.net.

1. Namespaces Presented By: Ms Richa Handa

2. The most common way that VB.NET namespaces are used by most programmers is to tell the compiler which .NET Framework libraries are needed for a particular program. .NET codes can be organized using namespaces. Namespaces organize the objects defined in an assembly. Namespaces are not replacements for assemblies, but a second organizational method that complete assemblies. Namespaces are a way of grouping type names and reduce the chance of name collisions.

3. Example: For example a button type is contained in system.windows.forms namespace. This is actually shorthand for the situation shown in figure below: Button class Form Namespace Window Namespace System Namespace

4. Declare a namespace System  is the basic namespace used by every .NET code. There are lots of namespace user the system namespace. For example, System.IO, System.Net , System.Collections , System.Threading , System.Data , Ststem.Drawing , etc.

5. VB.NET Code: Namespace College Namespace students Imports System Class  Addstudents Public Function  S_Method () Console.WriteLine ("Adding Students to college using S_Method !") End Function End Class End Namespace End Namespace

6. Let's look how we can use the namespaces in our code. I'm going to create a program to use the namespaces. VB.NET Code: Imports System Class  HelloWorld Public Sub Main() Dim  AddStd  As  Student.AddStudent = New  AddStudent AddStd.S_Method () End Sub End Class
