I know this is an old post but there was no answer, and I'm glad to be able to finally contribute

I had to get the extension for a project I'm working on, here is how I did it. Since you are getting the file name, you can grab the extension from that:

Sub MyNiftyMethod
    ...process stuff...
    Dim strFileName As String = "something.pdf"
    Dim strExtension As String = GetExtension(strFileName)
    Log(strExtension)
    'prints out: pdf
End Sub

Sub GetExtension(strFileName As String) As String
	If strFileName.IndexOf(".") > 0 Then
		Dim parts() As String = Regex.Split("\.", strFileName)
		Return parts(parts.Length - 1)
	Else
		Return Null
	End If
End Sub
