Issue in adding paragraphs to pdf usimg itextsharp

I have the following code whose output in a pdf file is:

Form M.T.R. 17

PAY-BILL OF GAZETTED OFFICER

                                DDO Code: 703

The code is:

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.IO;

using iTextSharp.text;
using iTextSharp.text.pdf;
public partial class new_salary : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        HttpContext.Current.Response.Clear();
        HttpContext.Current.Response.ContentType = "application/pdf";

        // Create PDF document
        Document pdfDocument = new Document(PageSize.A4, 70, 45, 40, 25);

        PdfWriter wri = PdfWriter.GetInstance(pdfDocument, new FileStream("d://JudgeSalary.pdf", FileMode.Create));

        PdfWriter.GetInstance(pdfDocument, HttpContext.Current.Response.OutputStream);

        pdfDocument.Open();

        Chunk boo = new Chunk("Form M.T.R. 17");


        Paragraph main1 = new Paragraph("Form M.T.R. 17 \nPAY-BILL OF GAZETTED OFFICER");
        main1.Alignment = Element.ALIGN_CENTER;
        main1.Font.SetStyle(Font.BOLD);

        Paragraph main1a = new Paragraph("          DDO Code: 703");
        main1a.Alignment = Element.ALIGN_RIGHT;





        pdfDocument.Add(main1);
        pdfDocument.Add(main1a);

        pdfDocument.Close();
        HttpContext.Current.Response.End();
    }
}

I want the output to be:

               **Form M.开发者_JAVA百科T.R. 17**

               **PAY-BILL OF GAZETTED OFFICER**                           DDO Code: 703

How can i get the above mentioned output with 'DDO Code: 703' in the 2nd line of the paragraph and no text formatting . If i include 'DDO Code: 703' in 'para1' than the text is displayed as bold. I want this output to be center alignment accept 'DDO Code: 703' which i want to be right aligned.

I dont want it to appear bold and also want it in the 2nd line of the paragraph. how can i do it?

Using iTextSharp, you can add text with a Chunk, Phrase, or Paragraph. See a reference of how these work here. Essentially, you will want to put your paragraph together as a few phrases or chunks to allow for the differing font styles.

To achieve the positioning you want, a PdfPTable with appropriately aligned PdfPCell elements may work best. Something like the following:

PdfPTable table = new PdfPTable(2);
PdfPCell cell = new PdfPCell(new Phrase("Form M.T.R. 17", FontFactory.GetFont(FontFactory.TIMES_ROMAN, 12, iTextSharp.text.Font.BOLD)));
cell.Colspan = 2;
cell.Border = 0;
cell.HorizontalAlignment = Element.ALIGN_LEFT; 
table.AddCell(cell);
table.AddCell(new Phrase("PAY-BILL OF GAZETTED OFFICER"));

PdfPCell rCell = new PdfPCell(new Phrase("DDO Code: 703", FontFactory.GetFont(FontFactory.TIMES_ROMAN, 12)));
rCell.Border = 0;
rCell.HorizontalAlignment = Element.ALIGN_RIGHT; 
table.AddCell(rCell);
pdfDocument.Add(table);

A paragraph will be in a new line, try to use Phrase like this:

Phrase main1 = new Phrase("Form M.T.R. 17 \nPAY-BILL OF GAZETTED OFFICER");
main1.Font.SetStyle(Font.BOLD);

Phrase main1a = new Paragraph(" DDO Code: 703");

pdfDocument.Add(main1);
pdfDocument.Add(main1a);
