How to introduce new line characters with iTextSharp

I have written following code to write text in PDF and i want to break the line after some text .

 Dim document As Document

    document = New Document(PageSize.A4, 5.0F, 20.0F, 20.0F, 20.0F)

    Try

        Dim writer As PdfWriter
        writer = PdfWriter.GetInstance(document, New FileStream(filename, FileMode.Create))

        document.Open()

        Dim spacing As Integer

        spacing = 0

        Dim curY, lineHeight As Double

        curY = document.Top
        lineHeight = 0

        Const maxPerLine As Integer = 3


        For i As Integer = 0 To 5

            Dim table As PdfPTable
            table = New PdfPTable(4)

            table.DefaultCell.Border = Rectangle.NO_BORDER
            table.TotalWidth = 200.0F
            table.LockedWidth = True

            Dim cell As PdfPCell
            cell = New PdfPCell(New Phrase("hello \n" + i + "\n" + "wass up ?" ))
            cell.Colspan = 4
            cell.HorizontalAlignment = 0
            cell.Border = Rectangle.NO_BORDER
            cell.Padding = 30.0F
            table.AddCell(cell)

            table.WriteSelectedRows(0, -1, document.Left + spacing, curY, writer.DirectContent)

            spacing = spacing + 200

            lineHeight = Math.Max(lineHeight, table.TotalHeight)

            If 0 = (i + 1) Mod maxPerLine Then

                curY = curY - lineHeight
                spacing = 0
                lineHeight = 0

            End If

        Next

    Catch ex As Exception

    Finally

        document.Close()


    End Try

i have tried with Paragraph but still i am not able to enter texts into new line.

I have read the doc of iTextSharp they have written if you want to break line then use "\n" but it is not working.

How can i break line after some text ?

The easiest way, is to use PdfPCell in composite mode (you're using text mode). Composite mode gets into play when you use AddElement:

Dim cell As PdfPCell
cell = New PdfPCell()
cell.AddElement(New Paragraph("line 1"))
cell.AddElement(New Paragraph("line 2"))

Note that you can't set the alignment at the level of the PdfPCell in this case. When using composite mode, you have to set the alignment at the level of the elements (in this case at the level of the Paragraph).
