用itextsharp实现Pdf生成 （C#代码）

string path = Server.MapPath("PDFiles");

string filestr = DateTime.Now.ToString("yyyyMMddHHmmss") + ".pdf";

string filename = path + "/" +filestr; //尽量采用变量

//第一步：创建一个新PDF Document对象,设置纸张为A4，左右上下边距，单位为磅，72磅=1英寸=25.4毫米

Document document = new Document(PageSize.A4, 36, 36, 36, 36);

//第二步：创建PdfWriter

PdfWriter writer=PdfWriter.GetInstance(document, new FileStream(filename, FileMode.Create));

//第三步：打开文档()

writer.PageEvent = new PDFHeaderFooter(); //如果不要页面页脚请注释该行

document.Open();

//第四步：写文档（页眉页脚、文字、表格、图片、）

//1.中文字体支持

//黑体

BaseFont bfComic = BaseFont.CreateFont(@"C:\Windows\Fonts\SIMHEI.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);

//宋体

BaseFont bfSun = BaseFont.CreateFont(@"C:\Windows\Fonts\SIMSUN.TTC,1", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);

//字体大小

Font fontHead = new Font(bfSun, 24);

Font fontText = new Font(bfSun, 16);

//以下两行用于排版控制

document.Add(new Paragraph(" "));

document.Add(new Paragraph(" "));

//2.PDF表格

PdfPTable tab = new PdfPTable(3);

PdfPCell cell = new PdfPCell(new Phrase("业务数据展示", fontHead));

cell.Colspan = 3;

cell.HorizontalAlignment = 1; //0=Left, 1=Centre, 2=Right

cell.BorderColor = new BaseColor(System.Drawing.Color.Red);

cell.Border = Rectangle.BOTTOM_BORDER; // | Rectangle.TOP_BORDER;

cell.BorderWidthBottom = 3f;

tab.AddCell(cell);

//第一行

for (int i = 0; i < dt.Rows.Count; i++)

{

tab.AddCell(dt.Rows[i][0].ToString());

PdfPCell cellB = new PdfPCell(new Phrase(dt.Rows[i][1].ToString(), fontText));

tab.AddCell(cellB);

tab.AddCell(dt.Rows[i][4].ToString());

}

//第二行

tab.AddCell(dt.Rows[0][0].ToString());

PdfPCell cellC = new PdfPCell(new Phrase(dt.Rows[0][1].ToString(), fontText));

tab.AddCell(cellC);

tab.AddCell(dt.Rows[0][2].ToString());

//第三行（跨单元格）

cell = new PdfPCell();

cell.Colspan = 3;

iTextSharp.text.List pdfList = new List(List.ALPHABETICAL); //支持数字、字母、无序号等列表显示

pdfList.Add(new iTextSharp.text.ListItem(dt.Rows[0][0].ToString()));

pdfList.Add(dt.Rows[0][1].ToString());

pdfList.Add(dt.Rows[0][2].ToString());

pdfList.Add(dt.Rows[0][3].ToString());

cell.AddElement(pdfList);

tab.AddCell(cell);

document.Add(tab);

//3.文字输出

document.Add(new Paragraph("Welcome to doptech,德璞欢迎您！",fontText));

//坐标式文字输出

PdfContentByte cb = writer.DirectContent;

cb.BeginText();

cb.SetFontAndSize(bfSun, 12);

cb.ShowTextAligned(PdfContentByte.ALIGN_CENTER, "This text is centered 看到了吗", 200, 500, 0);

cb.EndText();

//划线-含二维绘图方法

cb.SetLineWidth(8f);

cb.SetLineDash(40f);

cb.MoveTo(100, 550);

cb.LineTo(500, 550);

cb.Stroke();

// 4.显示图片

iTextSharp.text.Image img1 = iTextSharp.text.Image.GetInstance(Server.MapPath("images/Tulips.jpg"));

img1.ScaleToFit(50, 30);

Chunk ck=new Chunk(img1,50,50);

document.Add(img1);

iTextSharp.text.Image img2 = iTextSharp.text.Image.GetInstance(Server.MapPath("images/Tulips.jpg"));

img2.ScaleToFit(500, 800);

img2.Alignment = Element.ALIGN_CENTER | Element.ALIGN_MIDDLE;

document.Add(img2);

iTextSharp.text.Image img3 = iTextSharp.text.Image.GetInstance(Server.MapPath("images/bbtn.jpg"));

cb.MoveTo(300, 300);

cb.AddImage(img3, 300, 300, 100, 100, 100, 100);

//cb.AddImage(logo,100,100,100,100,100,100);

//第五步：关闭文档

document.Close();
