You should take a look to online documentation, btw a common snippet to achieve your task is follow:

Using stream As New MemoryStream
          Using doc As New iTextSharp.text.Document(PageSize.A4, 0, 0, 0, 0)
Using writer As iTextSharp.text.pdf.PdfWriter = iTextSharp.text.pdf.PdfWriter.GetInstance(doc, stream)

  writer.CloseStream = False
  Dim xmlWorker = XMLWorkerHelper.GetInstance()

  doc.Open()


  Dim _helperWiter As New StringWriter

  // the page to convert to PDF
  HttpContext.Current.Server.Execute(String.Format("../Reports/Templates/Page.aspx", _helperWiter)
  Using reader As New StringReader(_helperWiter.ToString())
    xmlWorker.ParseXHtml(writer, doc, reader)

  End Using
  doc.Close()
  writer.Close()
  stream.Close()

  Response.ContentType = "pdf/application"
  Response.AddHeader("content-disposition", String.Format("attachment;filename={0}.pdf", filemane))

  Response.BufferOutput = False
  Response.BinaryWrite(stream.ToArray())

  Response.Flush()
  Response.Close()
  Response.End()

    End Using
  End Using
End Using
