C#生成PDF（含iTextSharp.dll）
示例源码 //Document:（文档）生成pdf必备的一个对象,生成一个Document示例 Document document = new Document(PageSize.A4, 30, 30, 5, 5); //为该Document创建一个Writer实例： PdfWriter.GetInstance(document, new FileStream(Server.MapPath("/upload/"+"Chap0101.pdf"), FileMode.Create)); //打开当前Document document.Open(); //为当前Document添加内容： document.Add(new Paragraph("Hello World")); //另起一行。有几种办法建立一个段落，如： Paragraph p1 = new Paragraph(new Chunk("This is my first paragraph.\n", FontFactory.GetFont(FontFactory.HELVETICA, 12))); Paragraph p2 = new Paragraph(new Phrase("This is my second paragraph.", FontFactory.GetFont(FontFactory.HELVETICA, 12))); Paragraph p3 = new Paragraph("This is my third paragraph.", FontFactory.GetFont(FontFactory.HELVETICA, 12)); //所有有些对象将被添加到段落中： p1.Add("you can add string here\n\t"); p1.Add(new Chunk("you can add chunks \n")); p1.Add(new Phrase("or you can add phrases.\n")); document.Add(p1); document.Add(p2); document.Add(p3); //创建了一个内容为“hello World”、红色、斜体、COURIER字体、尺寸20的一个块： Chunk chunk = new Chunk("Hello world", FontFactory.GetFont(FontFactory.COURIER, 20, iTextSharp.text.Font.COURIER, new iTextSharp.text.Color(255, 0, 0))); document.Add(chunk); //如果你希望一些块有下划线或删除线，你可以通过改变字体风格简单做到： Chunk chunk1 = new Chunk("This text is underlined", FontFactory.GetFont(FontFactory.HELVETICA, 12, iTextSharp.text.Font.UNDEFINED)); Chunk chunk2 = new Chunk("This font is of type ITALIC | STRIKETHRU", FontFactory.GetFont(FontFactory.HELVETICA, 12, iTextSharp.text.Font.ITALIC | iTextSharp.text.Font.STRIKETHRU)); //改变块的背景 chunk2.SetBackground(new iTextSharp.text.Color(0xFF, 0xFF, 0x00)); //上标/下标 chunk1.SetTextRise(5); document.Add(chunk1); document.Add(chunk2); //外部链接示例： Anchor anchor = new Anchor("website", FontFactory.GetFont(FontFactory.HELVETICA, 12, iTextSharp.text.Font.UNDEFINED, new iTextSharp.text.Color(0, 0, 255))); anchor.Reference = "http://itextsharp.sourceforge.net/"; anchor.Name = "website"; //内部链接示例： Anchor anchor1 = new Anchor("This is an internal link\n\n"); anchor1.Name = "link1"; Anchor anchor2 = new Anchor("Click here to jump to the internal link\n\f"); anchor2.Reference = "#link1"; document.Add(anchor); document.Add(anchor1); document.Add(anchor2); //排序列表示例： List list = new List(true, 20); list.Add(new iTextSharp.text.ListItem("First line")); list.Add(new iTextSharp.text.ListItem("The second line is longer to see what happens once the end of the line is reached. Will it start on a new line?")); list.Add(new iTextSharp.text.ListItem("Third line")); document.Add(list); //文本注释： Annotation a = new Annotation("authors", "Maybe its because I wanted to be an author myself that I wrote iText."); document.Add(a); //包含页码没有任何边框的页脚。 HeaderFooter footer = new HeaderFooter(new Phrase("This is page: "), true); footer.Border = iTextSharp.text.Rectangle.NO_BORDER; document.Footer = footer; //Chapter对象和Section对象自动构建一个树： iTextSharp.text.Font f1 = new iTextSharp.text.Font(); f1.SetStyle(iTextSharp.text.Font.BOLD); Paragraph cTitle = new Paragraph("This is chapter 1", f1); Chapter chapter = new Chapter(cTitle, 1); Paragraph sTitle = new Paragraph("This is section 1 in chapter 1", f1); Section section = chapter.AddSection(sTitle, 1); document.Add(chapter); //构建了一个简单的表： iTextSharp.text.Table aTable = new iTextSharp.text.Table(4, 4); aTable.AutoFillEmptyCells = true; aTable.AddCell("2.2", new Point(2, 2)); aTable.AddCell("3.3", new Point(3, 3)); aTable.AddCell("2.1", new Point(2, 1)); aTable.AddCell("1.3", new Point(1, 3)); document.Add(aTable); //构建了一个不简单的表： iTextSharp.text.Table table = new iTextSharp.text.Table(3); table.BorderWidth = 1; table.BorderColor = new iTextSharp.text.Color(0, 0, 255); table.Cellpadding = 5; table.Cellspacing = 5; Cell cell = new Cell("header"); cell.Header = true; cell.Colspan = 3; table.AddCell(cell); cell = new Cell("example cell with colspan 1 and rowspan 2"); cell.Rowspan = 2; cell.BorderColor = new iTextSharp.text.Color(255, 0, 0); table.AddCell(cell); table.AddCell("1.1"); table.AddCell("2.1"); table.AddCell("1.2"); table.AddCell("2.2"); table.AddCell("cell test1"); cell = new Cell("big cell"); cell.Rowspan = 2; cell.Colspan = 2; cell.BackgroundColor = new iTextSharp.text.Color(0xC0, 0xC0, 0xC0); table.AddCell(cell); table.AddCell("cell test2"); // 改变了单元格“big cell”的对齐方式： cell.HorizontalAlignment = Element.ALIGN_CENTER; cell.VerticalAlignment = Element.ALIGN_MIDDLE; document.Add(table); //关闭Document document.Close();
