MVC 生成PDf表格并插入图片
最近做的项目中有一个功能，将最终的个人信息生成PDF表格，并插入图片。对于没接触过的程序员来说回一片茫然，网上有多种生成PDf的方法，我给大家介绍一下我认为比较简单，好操作的一种。
iTextSharp组件
使用方法。
1，引入itextsharp.dll
2, 引入命名空间
using iTextSharp; using iTextSharp.text; using iTextSharp.text.pdf;
Document document = new Document();
string filepath = "/Upload/Pdf/"; Directory.CreateDirectory(HttpContext.Current.Server.MapPath(filepath));
PdfWriter.GetInstance(document, new FileStream(HttpContext.Current.Server.MapPath(filepath + model.ExamNo + ".pdf"), FileMode.Create));
document.Open();
BaseFont bftitle = BaseFont.CreateFont(@"C:\\Windows\Fonts\SIMHEI.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); Font fonttitle = new Font(bftitle, 20, Font.UNDERLINE); BaseFont bf1 = BaseFont.CreateFont(@"C:\\Windows\Fonts\SIMSUN.TTC,1", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED); Font font1 = new Font(bf1, 12); Font fonttitle10 = new Font(bf1, 12); Font fonttitle12 = new Font(bf1, 11); PdfPCell cellmode = new PdfPCell();
//因为显示照片部分显示5列，而后续部分显示四列，所以创建两个table PdfPTable table = new PdfPTable(4); PdfPTable tablerow = new PdfPTable(5);
不一步一步赘述了，将详细代码奉上。
public void CreatePersonInfo(RBS.Models.UserConfirmModel model)
{
Document document = new Document();
string filepath = "/Upload/Pdf/";
Directory.CreateDirectory(HttpContext.Current.Server.MapPath(filepath));
PdfWriter.GetInstance(document, new FileStream(HttpContext.Current.Server.MapPath(filepath + model.ExamNo + ".pdf"), FileMode.Create));
document.Open();
BaseFont bftitle = BaseFont.CreateFont(@"C:\\Windows\Fonts\SIMHEI.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
Font fonttitle = new Font(bftitle, 20, Font.UNDERLINE);
BaseFont bf1 = BaseFont.CreateFont(@"C:\\Windows\Fonts\SIMSUN.TTC,1", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
Font font1 = new Font(bf1, 12);
Font fonttitle10 = new Font(bf1, 12);
Font fonttitle12 = new Font(bf1, 11);
PdfPCell cellmode = new PdfPCell();
PdfPTable table = new PdfPTable(4);
PdfPTable tablerow = new PdfPTable(5);
float padding = 0f;
