    2、PDF转换方法

            /// <summary>
            /// datatable转PDF方法
            /// </summary>
            /// <param name="Data">dataTable数据</param>
            /// <param name="PDFFile">PDF文件保存的路径</param>
            /// <param name="FontSize">字体大小</param>
            /// <returns></returns>
            public bool ConvertDataTableToPDF(DataTable Data, string PDFFile, float FontSize)
            {
                //默认页面大小
                Document document = new Document();
                document.SetPageSize(PageSize.A2);
                PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(PDFFile, FileMode.Create));
                document.Open();
                //设置字体
                //BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
                //Font font = new Font(bf, FontSize);
                //设置字体,支持中文
                BaseFont bfChinese = BaseFont.CreateFont("C:\WINDOWS\Fonts\simsun.ttc,1", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
                iTextSharp.text.Font fontChinese = new iTextSharp.text.Font(bfChinese, 12, iTextSharp.text.Font.NORMAL, new BaseColor(0, 0, 0));
    
                PdfPTable table = new PdfPTable(Data.Columns.Count);
                table.WidthPercentage = 100; // percentage          
                table.DefaultCell.Padding = 1;
                table.DefaultCell.BorderWidth = 1;
                table.DefaultCell.HorizontalAlignment = Element.ALIGN_LEFT;
                //将datatable表头转换成PDFTable的表头
                foreach (DataColumn dc in Data.Columns)
                {
                    table.AddCell(new Phrase(dc.ColumnName.ToString(), fontChinese));
                }
                //插入数据
                for (int i = 0; i < Data.Rows.Count; i++)
                {
                    for (int j = 0; j < Data.Columns.Count; j++)
                    {
                        table.AddCell(new Phrase(Data.Rows[i][j].ToString(), fontChinese));
                    }
                }
                document.Add(table);
                document.Close();
                writer.Close();
                return true;
            }

    3、调用代码

            private void btnCreatePDF_Click(object sender, EventArgs e)
            {
                //获取datatable数据
                DataTable tab = GetDataTableList();
                //获取保存路径
                string savePath = "D://PDF//";
                string saveName = "PDF文件.pdf";
                CreateFileDirectory(savePath);
                //文件路径:保存路径+保存名称
                string path = savePath + saveName;
                //调用转化PDF的方法
                ConvertDataTableToPDF(tab,path,12);
            }

    4、调用界面

     5、生成结果
