This code demonstrates the use of Function OverLoading, which can prove quite handy when designing commercial and enterprise components.

 Imports system
Imports microsoft.visualbasic ' For msgbox
 
Namespace N1
    Class Ovrl
      Shared Sub main()
        myfunc("Mansih")
        myfunc(22)
      End Sub

      'Accepts Integer
      Overloads Shared Function myfunc
(ByVal i As Integer) As String
        msgbox("Overloaded Function Accepting Integer")
      End Function

     'Accepts String
     Overloads Shared Function myfunc(ByVal s As String
) As String
        msgbox("Overloaded Function Accepting String")
     End Function
   End Class
End Namespace

The previous example demonstrated Function Overloading. It is also possible to overload a constructor -- it's also one of my favorite features:

Imports system
Imports microsoft.visualbasic ' For msgbox

Namespace N1
    Class OvrConst
      Shared Sub main()
        Dim o As New OvrConst()
        Dim x As New OvrConst("Constructor 2")
      End Sub

      'cosntructor 1 without parameter
      Public Overloads Sub New()
         msgbox("Constructor 1")
      End Sub

      'cosntructor 2 with a String parameter
      Public Overloads Sub New(ByVal s )
        msgbox(s)
      End Sub

    End Class
End Namespace
