一、新建项目:pdfdemo
<ItemGroup>
<PackageReference Include="iTextSharp.LGPLv2.Core" Version="3.4.20" />
</ItemGroup>
二、HomeController.cs
cs
using iTextSharp.text;
using iTextSharp.text.pdf;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Logging;
using pdfdemo.Models;
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.IO;
using System.Linq;
using System.Threading.Tasks;
namespace pdfdemo.Controllers
{
public class HomeController : Controller
{
private readonly ILogger<HomeController> _logger;
public HomeController(ILogger<HomeController> logger)
{
_logger = logger;
}
public IActionResult Index()
{
var path = $"{AppDomain.CurrentDomain.BaseDirectory}/{DateTime.Now.ToFileTime()}.pdf";
var document = new Document(PageSize.A4.Rotate());
document.SetMargins(10, 10, 50, 10);
using (var fileStream = new FileStream(path, FileMode.Create))
{
var writer = PdfWriter.GetInstance(document, fileStream);
document.Open();
var rowHeight = 25;
var table = new PdfPTable(6);
table.WidthPercentage = 100;
var cellTdDes = new PdfPCell(new Phrase("A"));
cellTdDes.Colspan = 3;
cellTdDes.HorizontalAlignment = Element.ALIGN_LEFT;
cellTdDes.VerticalAlignment = Element.ALIGN_MIDDLE;
cellTdDes.FixedHeight = rowHeight;
table.AddCell(cellTdDes);
var cellQuantityHeader = new PdfPCell(new Phrase("B"));
WrapCell(rowHeight, cellQuantityHeader);
var cellPriceHeader = new PdfPCell(new Phrase("C"));
WrapCell(rowHeight, cellPriceHeader);
var cellAmountHeader = new PdfPCell(new Phrase("D"));
WrapCell(rowHeight, cellAmountHeader);
table.AddCell(cellQuantityHeader);
table.AddCell(cellPriceHeader);
table.AddCell(cellAmountHeader);
var baseFont = BaseFont.CreateFont(@"c:/windows/fonts/SIMHEI.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
var font = new iTextSharp.text.Font(baseFont, 10, iTextSharp.text.Font.NORMAL);
var fixedHeight = 40;
for (int i = 0; i < 8; i++)
{
var cellTd = new PdfPCell(new Phrase("你好", font));
cellTd.Colspan = 3;
cellTd.FixedHeight = fixedHeight;
cellTd.VerticalAlignment = Element.ALIGN_MIDDLE;
table.AddCell(cellTd);
var cellQuantity = new PdfPCell(new Phrase("66"));
WrapCell(fixedHeight, cellQuantity);
var cellPrice = new PdfPCell(new Phrase("666"));
WrapCell(fixedHeight, cellPrice);
var cellAmount = new PdfPCell(new Phrase("666"));
WrapCell(fixedHeight, cellAmount);
table.AddCell(cellQuantity);
table.AddCell(cellPrice);
table.AddCell(cellAmount);
}
document.Add(table);
writer.Flush();
document.Close();
document.Dispose();
}
return View();
}
private static void WrapCell(int fixedHeight, PdfPCell cell)
{
cell.HorizontalAlignment = Element.ALIGN_RIGHT;
cell.VerticalAlignment = Element.ALIGN_MIDDLE;
cell.FixedHeight = fixedHeight;
}
}
}
运行效果:
