What is Namespace in VB.net.

1. 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. 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.  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
