The following demo code will explain how to add header or footer to PDF file using C#.

String inputFilePath = Program.RootPath + "\\" + "1.pdf";
String outputFilePath = Program.RootPath + "\\" + "1_hdrftr.pdf";

//  open a PDF file
PDFDocument doc = new PDFDocument(inputFilePath);

{
    //  define a header/footer setting
    PDFPageHeaderFooter hdrftr1 = new PDFPageHeaderFooter();
    //  set center header field
    hdrftr1.CenterHeaderField.Set(@"Title: *****", new Font("Arial", 12F, FontStyle.Regular), Color.Black);
    //  set left footer field
    hdrftr1.LeftFooterField.Set("Page <<1/n>>", new Font("Arial", 9F, FontStyle.Regular), Color.DarkGray);

    //  define page range: all odd pages
    PageRangeOptions pageRange1 = new PageRangeOptions();
    pageRange1.AllPages = true;
    pageRange1.Subset = PageRangeSubset.Odd;

    //  apply header/footer settings to all odd pages
    PDFPageFieldHandler.ApplyHeaderFooter(doc, hdrftr1, pageRange1);
}
{
    //  define a header/footer setting
    PDFPageHeaderFooter hdrftr2 = new PDFPageHeaderFooter();
    //  set center header field
    hdrftr2.CenterHeaderField.Set(@"Title: *****", new Font("Arial", 12F, FontStyle.Regular), Color.Black);
    //  set right footer field
    hdrftr2.RightFooterField.Set("Page <<1/n>>", new Font("Arial", 9F, FontStyle.Regular), Color.DarkGray);

    //  define page range: all even pages
    PageRangeOptions pageRange2 = new PageRangeOptions();
    pageRange2.AllPages = true;
    pageRange2.Subset = PageRangeSubset.Even;

    //  apply header/footer settings to all even pages
    PDFPageFieldHandler.ApplyHeaderFooter(doc, hdrftr2, pageRange2);
}

doc.Save(outputFilePath);

Remove all Page Header/Footer settings in a PDF document object using C#

String inputFilePath = Program.RootPath + "\\" + "1_hdrftr.pdf";
String outputFilePath = Program.RootPath + "\\" + "output.pdf";

PDFDocument doc = new PDFDocument(inputFilePath);
PDFPageFieldHandler.RemoveHeaderFooters(doc);
doc.Save(outputFilePath);

Retrieve all Page Header/Footer settings from a PDF file using C#

String inputFilePath = Program.RootPath + "\\" + "1_hdrftr.pdf";

PDFDocument doc = new PDFDocument(inputFilePath);

//  get all Header/Footer settings in the document
PDFPageHeaderFooterInfo info = PDFPageFieldHandler.RetreiveHeaderFooters(doc);

//  get default setting for Header/Footer and Page Range
PDFPageHeaderFooter defaultSetting = info.GetDefaultSetting();
PageRangeOptions defaultPageRange = info.GetDefaultPageRangeSettings();
