C# 利用ITextSharp导出PDF文件

最近项目中需要导出PDF文件，最后上网搜索了一下，发现ITextSharp比较好用，所以做了一个例子：

public string ExportPDF()

        {

            //ITextSharp Usage

            //Steps:1. Add content to cell;2. Add cell to table;3. Add table to document;4. Add document to rectangle;

            string sAbsolutePath = ControllerContext.HttpContext.Server.MapPath(this.path);

            string FileName = string.Format("Notice_{0}.pdf", DateTime.Now.ToString("yyyyMMddHHmmss"));

            BaseFont bf = BaseFont.CreateFont("C:/WINDOWS/Fonts/Arial.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);

            Rectangle rec = new Rectangle(, );

            Document document = new Document(rec);

            document.SetMargins(10f, 10f, 10f, 10f);

            PdfWriter pdfwriter = PdfWriter.GetInstance(document,

                    new System.IO.FileStream(sAbsolutePath + "\\" + FileName, System.IO.FileMode.Create)

                );

            document.Open();

            Font font = new Font(bf);

            try

            {

                PdfPTable pdftable = new PdfPTable();

                pdftable.HorizontalAlignment = ;

                //Set cell width

                float[] cellwidth = { 3f, 5f, 5f, 3.5f, 5f };

                pdftable.SetWidths(cellwidth);

                //Header

                Font PDFFontA = FontFactory.GetFont("Arial", , Font.BOLD);

                Font PDFFontB = FontFactory.GetFont("Arial", , Font.BOLD);

                Font PDFFontC = FontFactory.GetFont("Arial", );

                //Image Object

                Image jpeg = Image.GetInstance(HttpContext.Server.MapPath("../images/buddy.jpg"));

                PdfPCell cell = new PdfPCell(jpeg);

                cell.FixedHeight = 40f;

                cell.Colspan = ;

                cell.Rowspan = ;

                cell.Border = ;

                pdftable.AddCell(cell);

                cell = new PdfPCell(new Phrase(("Did You Know?"), PDFFontB));

                cell.Colspan = ;

                cell.Rowspan = ;

                cell.Border = ;

                cell.BackgroundColor = new BaseColor(, , );//RGB Color Value

                cell.HorizontalAlignment = ;

                pdftable.AddCell(cell);

                cell = new PdfPCell(new Phrase("\nTitle: Hello World!\nDate: " + DateTime.Now.ToString("MM/dd/yyyy") + "\n\n", PDFFontC));

                cell.Colspan = ;

                cell.Rowspan = ;

                cell.Border = ;

                cell.BackgroundColor = new BaseColor(, , );//RGB Color Value

                cell.HorizontalAlignment = ;

                pdftable.AddCell(cell);

                cell = new PdfPCell(new Phrase("Notice", PDFFontA));

                cell.BackgroundColor = new BaseColor(, , );//RGB Color Value

                cell.Colspan = ;

                cell.Padding = 5f;

                cell.HorizontalAlignment = ;

                pdftable.AddCell(cell);

                string[] AssHeader = { "DateTime", "Name", "Description", "Icon", "Notes"};

                for (int i = ; i < AssHeader.Length; i++)

                {

                    cell = new PdfPCell(new Phrase(AssHeader[i], PDFFontB));

                    cell.HorizontalAlignment = ;

                    cell.VerticalAlignment = Element.ALIGN_MIDDLE;

                    cell.BackgroundColor = new BaseColor(, , );

                    cell.PaddingBottom = 4f;

                    cell.PaddingTop = 4f;

                    pdftable.AddCell(cell);

                }

                for (int i = ; i < ; i++)

                {

                    cell = new PdfPCell(new Phrase(new DateTime().ToShortDateString(), PDFFontC));

                    cell.HorizontalAlignment = ;

                    cell.VerticalAlignment = Element.ALIGN_MIDDLE;

                    cell.PaddingBottom = 4f;

                    cell.PaddingTop = 4f;

                    pdftable.AddCell(cell);

                    cell = new PdfPCell(new Phrase("Jack Chean", PDFFontC));

                    cell.HorizontalAlignment = ;

                    cell.VerticalAlignment = Element.ALIGN_MIDDLE;

                    cell.PaddingBottom = 4f;

                    cell.PaddingTop = 4f;

                    pdftable.AddCell(cell);

                    cell = new PdfPCell(new Phrase("Just for my testing!!", PDFFontC));

                }

                //Very important

                //You can display the header in each page through this properity:HeaderRows

                pdftable.HeaderRows = ;

                document.Add(pdftable);
