这篇文章主要为大家详细介绍了c#生成pdf文件流的相关资料，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
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;
}
