Developing Namespaces in VB.NET 2005 - A simple example of a namespace

(Page 2 of 6 )

In my previous article (“Inheritance in VB.NET 2005”), I declared three classes, namely “First,” “Second” and “Third.”  I shall use the same solution and further extend it with examples of “namespaces.”

The simplest construction of a namespace would be as follows:

NamespaceNamespace1
EndNamespace

Every namespace should start with the keyword “Namespace” followed by the name of the namespace (in this case, it is “Namespace1”).  It is always recommended to name the namespace in a meaningful manner to identify a group of classes. 

To the same solution, add a new class file named “Namespace1_First.vb” and modify the code as follows:

NamespaceNamespace1
    Public Class First
        Private m_a As Integer
        Private m_b As Integer
        Public Sub New(ByVal x As Integer, ByVal y As Integer)
            m_a = x
            m_b = y
        End Sub
        Public Property A() As Integer
            Get
                Return m_a
            End Get
            Set(ByVal value As Integer)
                m_a = value
            End Set
        End Property
        Public Property B() As Integer
            Get
                Return m_b
            End Get
            Set(ByVal value As Integer)
                m_b = value
            End Set
        End Property
    End Class
EndNamespace

The next section will give you the explanation and sample code to activate the  example shown above.
