本文实例为大家分享了C#生成PDF文件流的具体代码，供大家参考，具体内容如下
1、设置字体
static BaseFont FontBase = BaseFont.CreateFont( "C:\WINDOWS\FONTS\STSONG.TTF" , BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
static iTextSharp.text.Font bodyFont = new iTextSharp.text.Font(FontBase, 12);
static iTextSharp.text.Font titleFont = new iTextSharp.text.Font(FontBase, 18);
static iTextSharp.text.Font paragraphFont = new iTextSharp.text.Font(FontBase, 15);
static iTextSharp.text.Font linkFont = new iTextSharp.text.Font(FontBase, 12, Font.UNDERLINE, BaseColor.BLUE);
2.生成PDF文件流返回byte数组
public byte [] DocCreate(System.Drawing.Image image, List<TreeNodes> list) { MemoryStream file = new MemoryStream(); string fileName = string.Empty; Rectangle page = PageSize.A4; float y = page.Height; Document document = new Document(page, 15, 15, 30, 30); float docWidth = page.Width - 15 * 2; float docHeight = page.Height - document.BottomMargin - document.TopMargin; PdfWriter writer = PdfWriter.GetInstance(document, file); writer.CloseStream = false ; writer.Open(); PdfContentByte cb = writer.DirectContent; document.Open(); //标题 Paragraph title = new Paragraph( new Chunk( "标题" , titleFont)); title.Alignment = Element.ALIGN_CENTER; document.Add(title); //图片 iTextSharp.text.Image img = iTextSharp.text.Image.GetInstance(image, ImageFormat.Png); float widthSzie = (page.Width - 30) / img.Width; if (widthSzie < 1) { img.ScalePercent(widthSzie * 100); } document.Add(img); //文献出处 Paragraph p2 = new Paragraph( new Chunk( "出处" , paragraphFont)); p2.IndentationLeft = indentationLeft; document.Add(p2); InitData(list); //初始化业务数据 CreateSteps(list, document, list.FirstOrDefault(it => it.PID == 0)); //添加业务数据 ////添加印章 //iTextSharp.text.Image whyz = iTextSharp.text.Image.GetInstance(whyzPath); //whyz.ScalePercent(50); //whyz.PaddingTop = 100; //whyz.Alignment = Element.ALIGN_RIGHT; //document.Add(whyz); //添加日期 Paragraph createtime = new Paragraph( new Chunk(DateTime.Now.ToLongDateString().ToString(), bodyFont)); createtime.Alignment = Element.ALIGN_RIGHT; //createtime.SpacingBefore = -80; createtime.PaddingTop = 200; document.Add(createtime); document.Close(); file.Position = 0; MemoryStream newfile = SetWaterMark(file, "水印内容" , docWidth, docHeight); //添加水印，见另外一篇博客 newfile.Position = 0; //重置流指针位置 byte [] bytes = new byte [newfile.Length]; newfile.Read(bytes, 0, bytes.Length); return bytes; }
