All .NET assemblies have metadata information stored about the types defined in modules.This metadata information can be accessed by mechanism called as “Reflection”.System.Reflection can
be used to browse through the metadata information.

Using reflection you can also dynamically invoke methods using System.Type.Invokemember.Below is sample source code if needed you can also get this code from CD provided , go to “Source
code” folder in “Reflection Sample” folder.

Public Class Form1

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim Pobjtype As Type

Dim PobjObject As Object

Dim PobjButtons As New Windows.Forms.Button()

Pobjtype = PobjButtons.GetType()

For Each PobjObject In Pobjtype.GetMembers

LstDisplay.Items.Add(PobjObject.ToString())

Next

End Sub

End Class
