C#使用iTextSharp+ZXing.Net+FreeSpire.PDF生成和打印pdf文檔

項目需求（Winform）可以批量打印某個模板，經過百度和摸索，使用iTextSharp+ZXing.Net+FreeSpire.PDF三個類庫實現了生成pdf、生成條形碼和打印pdf功能。

首先在項目作用使用NuGet獲取這三個類庫的引用。

其次把C:\Windows\Fonts里面的微軟雅黑字體復制到bin\debug\Fonts目錄下

以下為實現代碼：

using System;
using System.Diagnostics;
using System.Drawing;
using System.IO;
using System.Windows.Forms;
using Newtonsoft.Json;
using iTextSharp.text;
using iTextSharp.text.pdf;
using it = iTextSharp.text;
using System.Drawing.Imaging;
 
        //打印確認表
        private void Btn_print_Click(object sender, EventArgs e)
        {
            string path = Application.StartupPath + "\\PDFs";
            if (!Directory.Exists(path))
            {
                Directory.CreateDirectory(path);
            }
            //使用微軟雅黑字體，解決中文無法顯示，注意msyh.ttc后面的,0是必須的
            BaseFont baseFont = BaseFont.CreateFont(Application.StartupPath + "\\Fonts\\msyh.ttc,0", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
            it.Font font = new it.Font(baseFont, 14, it.Font.BOLD, it.BaseColor.BLACK);
            using (var doc1 = new Document(PageSize.A4, 5, 5, 35, 5))
            {
                PdfWriter.GetInstance(doc1, new FileStream(path + "\\Doc1.pdf", FileMode.Create));
                doc1.Open();
                //生成條形碼
                var bmp = ZXingHelper.GenerateBarcode("12345678900000");
                var txm = it.Image.GetInstance(System.Drawing.Image.FromHbitmap(bmp), ImageFormat.Bmp);
                //txm.ScalePercent(24f);
                txm.ScaleAbsoluteHeight(40);
                txm.SetAbsolutePosition(doc1.PageSize.Width - 220, doc1.PageSize.Height - 32);
                doc1.Add(txm);//把條形碼放到頁面右上角
