1. //PdfPTable saleTable = SaleTable();
2. FileStream fileStream = new FileStream(Customer + "Invoice.pdf",
3. FileMode.Create,
4. FileAccess.Write,
5. FileShare.None);
6. Document doc = new Document(PageSize.A4);
8. PdfWriter writer = PdfWriter.GetInstance(doc, fileStream);
9. doc.Open();
11. glue = new Chunk(new VerticalPositionMark());
12. _phrase1.Add(new Chunk(glue));
13. _phrase1.Add(new Chunk("Page Number: "));
15. _para.Add(_phrase1);

Hi,

Take a look at Spire.PDF, by which you can easily add the page x of y to the PDF document by creating footer.

Code for your reference:

static void AddFooter(PdfDocument doc, PdfMargins margin)
{
//Get the size of first page
SizeF pageSize = doc.Pages[0].Size;
//Create a PdfPageTemplateElement object that will be
//used as footer space
PdfPageTemplateElement footerSpace = new PdfPageTemplateElement(pageSize.Width, margin.Bottom);
footerSpace.Foreground = true;
doc.Template.Bottom = footerSpace;
//Draw text at the center of footer space
PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("Arial", 9f, FontStyle.Bold), true);
PdfStringFormat format = new PdfStringFormat(PdfTextAlignment.Center);
String headerText = "Copyright © 2017 xxx. All Rights Reserved.";
float x = pageSize.Width / 2;
float y = 15f;
footerSpace.Graphics.DrawString(headerText, font, PdfBrushes.Black, x, y, format);
//Create page number automatic field
PdfPageNumberField number = new PdfPageNumberField();
//Create page count automatic field
PdfPageCountField count = new PdfPageCountField();
//Add the fields in composite field
PdfCompositeField compositeField = new PdfCompositeField(font, PdfBrushes.Black, "Page {0} of {1}", number, count);
//Align string of "Page {0} of {1}" to center
compositeField.StringFormat = new PdfStringFormat(PdfTextAlignment.Center,PdfVerticalAlignment.Middle);
compositeField.Bounds = footerSpace.Bounds;
//Draw composite field at footer space
compositeField.Draw(footerSpace.Graphics);
}
static void Main(string[] args)
{
//Create a new PDF document
PdfDocument doc = new PdfDocument();
//Add two pages in it
PdfPageBase page = doc.Pages.Add();
doc.Pages.Add();
//Set the margin
PdfUnitConvertor unitCvtr = new PdfUnitConvertor();
PdfMargins margin = new PdfMargins();
margin.Top = unitCvtr.ConvertUnits(2.54f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point);
margin.Bottom = margin.Top;
margin.Left = unitCvtr.ConvertUnits(4.17f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point);
margin.Right = margin.Left;
//Call AddFooter method to add header information
AddFooter(doc, margin);
//Save the file
doc.SaveToFile("PDF_Footer.pdf");
doc.Close();
}

You need to inherit from PdfPageEventHelper class and override the methods shown in the code below:

document doc = new Document(PageSize.A4.Rotate());
using (MemoryStream ms = new MemoryStream())
{
PdfWriter writer = PdfWriter.GetInstance(doc, ms);
PageEventHelper pageEventHelper = new PageEventHelper();
writer.PageEvent = pageEventHelper;
}
public class PageEventHelper : PdfPageEventHelper
{
PdfContentByte cb;
PdfTemplate template;
public override void OnOpenDocument(PdfWriter writer, Document document)
{
cb = writer.DirectContent;
template = cb.CreateTemplate(50, 50);
}
public override void OnEndPage(PdfWriter writer, Document document)
{
base.OnEndPage(writer, document);
int pageN = writer.PageNumber;
String text = "Page " + pageN.ToString() + " of ";
float len = this.RunDateFont.BaseFont.GetWidthPoint(text, this.RunDateFont.Size);
iTextSharp.text.Rectangle pageSize = document.PageSize;
cb.SetRGBColorFill(100, 100, 100);
cb.BeginText();
cb.SetFontAndSize(this.RunDateFont.BaseFont, this.RunDateFont.Size);
cb.SetTextMatrix(document.LeftMargin, pageSize.GetBottom(document.BottomMargin));
cb.ShowText(text);
cb.EndText();
cb.AddTemplate(template, document.LeftMargin + len, pageSize.GetBottom(document.BottomMargin));
}
public override void OnCloseDocument(PdfWriter writer, Document document)
{
base.OnCloseDocument(writer, document);
template.BeginText();
template.SetFontAndSize(this.RunDateFont.BaseFont, this.RunDateFont.Size);
template.SetTextMatrix(0, 0);
template.ShowText("" + (writer.PageNumber - 1));
template.EndText();
}
}
