                   System.IO.File.Delete(file);


               Document document = new Document(PageSize.A4, 10, 10, 10, 10);

               var writer = iTextSharp.text.pdf.PdfWriter.GetInstance(document, new  System.IO.FileStream(file, FileMode.Create));
               document.Open();

               writer.PageEvent = new Footer();

               // main content

               document.Close();

               return 1;
           }
           catch (Exception ex)
           {
               throw ex;
           }


       }

       public partial class Footer : PdfPageEventHelper
       {
           public override void OnEndPage(PdfWriter writer, Document doc)
           {
               PdfPTable fTbl = new PdfPTable(1);
               fTbl.TotalWidth = 550;
               fTbl.DefaultCell.Border = 0;

               PdfPTable line = new PdfPTable(1);
               line.DefaultCell.Border = 0;
               line.DefaultCell.BorderWidthBottom = 0.2f;
               line.DefaultCell.Padding = 5;
               line.AddCell("");

               fTbl.AddCell(line);

               PdfPTable footerTbl = new PdfPTable(3);
               footerTbl.TotalWidth = 550;
               footerTbl.DefaultCell.Column.Alignment = 1;
               footerTbl.HorizontalAlignment = Element.ALIGN_CENTER;
               footerTbl.DefaultCell.Border = 0;

               footerTbl.AddCell("Print Name:");
               footerTbl.AddCell("Signature:");
               footerTbl.AddCell("Date:");


               PdfPCell cell = new PdfPCell();
               cell.Padding = 20;
               cell.Border = 0;
               cell.BorderWidthBottom = 1;

               footerTbl.AddCell(cell);
               footerTbl.AddCell(cell);
               footerTbl.AddCell(cell);

               fTbl.AddCell(footerTbl);
               fTbl.AddCell(line);

               fTbl.WriteSelectedRows(0, -1, 15, 110, writer.DirectContent);

               //footerTbl.WriteSelectedRows(0, -1, 15, 60, writer.DirectContent);
           }
       }
   }

推荐答案

I增加了文档的底部边距，所以现在页脚和内容不会相互重叠。



文档文档=新文档（PageSize.A4,10,10， 10,80）;

I have increased the bottom margin of document so now footer and content are not going to overlap each other.

Document document = new Document(PageSize.A4, 10, 10, 10, 80);
