友情提示：以下画PDF的代码是先创建PDF文件，然后往PDF里填充数据，如果不符合业务需求的，可以滑过
1、首先，添加iTextSharp包
2、添加PDF基类，供添加页脚、页眉、水印等
////// Pdf处理基类 /// public class PDFBase : PdfPageEventHelper { #region 属性 private String _fontFilePathForHeaderFooter = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Fonts), "SIMHEI.TTF"); ////// 页眉/页脚所用的字体 /// public String FontFilePathForHeaderFooter { get { return _fontFilePathForHeaderFooter; } set { _fontFilePathForHeaderFooter = value; } } private String _fontFilePathForBody = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Fonts), "SIMSUN.TTC,1"); ////// 正文内容所用的字体 /// public String FontFilePathForBody { get { return _fontFilePathForBody; } set { _fontFilePathForBody = value; } } private PdfPTable _header; ////// 页眉 /// public PdfPTable Header { get { return _header; } private set { _header = value; } } private PdfPTable _footer; ////// 页脚 /// public PdfPTable Footer { get { return _footer; } private set { _footer = value; } } private BaseFont _baseFontForHeaderFooter; ////// 页眉页脚所用的字体 /// public BaseFont BaseFontForHeaderFooter { get { return _baseFontForHeaderFooter; } set { _baseFontForHeaderFooter = value; } } private BaseFont _baseFontForBody; ////// 正文所用的字体 /// public BaseFont BaseFontForBody { get { return _baseFontForBody; } set { _baseFontForBody = value; } } private Document _document; ////// PDF的Document /// public Document Document { get { return _document; } private set { _document = value; } } #endregion public override void OnOpenDocument(PdfWriter writer, Document document) { try { BaseFontForHeaderFooter = BaseFont.CreateFont(FontFilePathForHeaderFooter, BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); BaseFontForBody = BaseFont.CreateFont(FontFilePathForBody, BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); Document = document; } catch (DocumentException de) { } catch (System.IO.IOException ioe) { } } #region GenerateHeader ////// 生成页眉 /// /// ///public virtual PdfPTable GenerateHeader(iTextSharp.text.pdf.PdfWriter writer) { return null; } #endregion #region GenerateFooter /// /// 生成页脚 /// /// ///public virtual PdfPTable GenerateFooter(iTextSharp.text.pdf.PdfWriter writer) { BaseFont baseFont = BaseFontForHeaderFooter; iTextSharp.text.Font font = new iTextSharp.text.Font(baseFont, 10, iTextSharp.text.Font.NORMAL); PdfPTable footer = new PdfPTable(3); AddFooterCell(footer, "甲方项目经理:", font); AddFooterCell(footer, "乙方代表：:", font); AddFooterCell(footer, "日期：", font); return footer; } private void AddFooterCell(PdfPTable foot, String text, iTextSharp.text.Font font) { PdfPCell cell = new PdfPCell(); cell.BorderWidthTop = 2; cell.BorderWidthRight = 0; cell.BorderWidthBottom = 0; cell.BorderWidthLeft = 0; cell.Phrase = new Phrase(text, font); cell.HorizontalAlignment = iTextSharp.text.Element.ALIGN_CENTER; foot.AddCell(cell); } #endregion public override void OnEndPage(iTextSharp.text.pdf.PdfWriter writer, iTextSharp.text.Document document) { base.OnEndPage(writer, document); 输出页眉 //Header = GenerateHeader(writer); //Header.TotalWidth = document.PageSize.Width - 20f; /调用PdfTable的WriteSelectedRows方法。该方法以第一个参数作为开始行写入。 /第二个参数-1表示没有结束行，并且包含所写的所有行。 /第三个参数和第四个参数是开始写入的坐标x和y. //Header.WriteSelectedRows(0, -1, 10, document.PageSize.Height - 20, writer.DirectContent); //输出页脚 Footer = GenerateFooter(writer); Footer.TotalWidth = document.PageSize.Width - 20f; Footer.WriteSelectedRows(0, -1, 10, document.PageSize.GetBottom(60), writer.DirectContent); } }
3、根据后台查出的数据画出PDF
///友情提示：在代码画PDF之前，最好自己先手动做一个范本（Excel），然后根据对应的行和列，代码画出
