VB Express 2005 open help

I just started programming with VB today and I'm trying to open and list the names of files in a text field here's my code so far. I'm getting the error:
"Reference to a non-shared member requires an object reference."
Declaraitons:

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Open As New System.Windows.Forms.OpenFileDialog()
Dim namegetter As System.IO.FileStream
Open.Filter = "All files (*.*)|*.*"
Open.CheckFileExists = True
Open.Title = "Open"
Open.ShowDialog(Me)
Try
Open.OpenFile()
namegetter = System.IO.FileInfo.Open(Open.FileNames)
TextBox1.Text = namegetter.Name()
Catch ex As Exception
' Do nothing on Exception
End Try
End Sub

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click

End Sub
End Class

I have 3 Buttons and a Text Box. I'm not sure what I am doing wrong or what I should be doing.
Help would be appreciated, Thanks.
