If you're working in VB and ended up here, the ".Where" threw an error for me. Got this from here: https://forums.asp.net/t/1067058.aspx?Trimming+a+string+to+remove+special+non+numeric+characters

Function ParseDigits(ByVal inputString as String) As String
  Dim numberString As String = ""
  If inputString = Nothing Then Return numberString

  For Each c As Char In inputString.ToCharArray()
    If c.IsDigit Then
      numberString &= c
    End If
  Next c

  Return numberString
End Function
