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

项目需求（winform）可以批量打印某个模板，经过百度和摸索，使用itextsharp+zxing.net+freespire.pdf三个类库实现了生成pdf、生成条形码和打印pdf功能。

首先在项目作用使用nuget获取这三个类库的引用。

其次把c:\windows\fonts里面的微软雅黑字体复制到bin\debug\fonts目录下

以下为实现代码：

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;
 
        //打印确认表
        private void btn_print_click(object sender, eventargs e)
        {
            string path = application.startuppath + "\\pdfs";
            if (!directory.exists(path))
            {
                directory.createdirectory(path);
            }
            //使用微软雅黑字体，解决中文无法显示，注意msyh.ttc后面的,0是必须的
            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();
                //生成条形码
                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);//把条形码放到页面右上角
