Shadowing: - When we have two programming elements with the same name and the code refers to the name they share the programming elements with closer scope or narrower scope is called as Shadowing. We can intentionally call a programming element by using shadows keyword. 

Ex1: -

Public Class Form2
Dim x As Integer = 10
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim x As Integer = 30
MsgBox(x)
End Sub
End Class

Output= 30

Ex2: -

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim a As New raj2
MsgBox(a.x)
End Sub
Public Class raj1
Public x As Integer = 10
End Class
Public Class raj2
Inherits raj1
Public Shadows ReadOnly Property x() As Integer
Get
Return 16
End Get
End Property
End Class
End Class
