iTextSharp生成pdf含模板（二）—C#代码部分

参考地址：https://www.cnblogs.com/ibeisha/p/itextsharp-pdf.html

一、先在程序中使用Nuget安装iTextSharp（我是创建的控制台程序）

二、建立静态常量类

     public class ConstantInfo
     {
         /// <summary>
         /// 证书下载目录
         /// </summary>
         public static string _Certificate { get { return "/DownloadResource/Certificate/"; } }         /// <summary>
         /// 证书模板目录
         /// </summary>
         public static string _CertificateTemplate { get { return "/Resources/"; } }
     }

三、生成pdf主体代码

     class Program
     {
         static void Main(string[] args)
         {
             //生成的pdf文件名称
             string fileName = "Certificate_test.pdf";
             //生成的pdf文件目录
             string downloadFilePath = AppDomain.CurrentDomain.BaseDirectory + ConstantInfo._Certificate;
             //生成的pdf文件完整路径
             string downloadFileName = downloadFilePath + fileName;
             //如没有，则创建
             if (!Directory.Exists(downloadFilePath))
             {
                 Directory.CreateDirectory(downloadFilePath);
             }
             //证书模板目录
             string templateFilePath = AppDomain.CurrentDomain.BaseDirectory + ConstantInfo._CertificateTemplate + "TemplateCer.pdf";
             //可直接写成固定目录
             //string tempFilePath = "D:\\tmp.pdf";
             //字体资源
             string fontFilePath = AppDomain.CurrentDomain.BaseDirectory + ConstantInfo._CertificateTemplate + "msyhbd.ttf";             iTextSharp.text.pdf.PdfReader pdfReader = new iTextSharp.text.pdf.PdfReader(templateFilePath);
             PdfStamper pdfStamper = new PdfStamper(pdfReader, new FileStream(downloadFileName, FileMode.OpenOrCreate));
             AcroFields pdfFormFields = pdfStamper.AcroFields;
             pdfStamper.FormFlattening = true;             //BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
             BaseFont simheiBase = BaseFont.CreateFont(fontFilePath, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);             //添加图片
             //Image image = Image.GetInstance("");
             //pdfStamper.Writer.Add(image);             pdfFormFields.AddSubstitutionFont(simheiBase);
             //根据pdf中对应的表单域（一定要一致）赋对应的值
             pdfStamper.AcroFields.SetField("Name", "小红");
             pdfStamper.AcroFields.SetField("Score", "");
             pdfStamper.AcroFields.SetField("CompanyName", "测试测试");
             pdfStamper.AcroFields.SetField("Date", "2019-7-17");
             //pdfStamper.AcroFields.SetField("chk", "yes", true);
             pdfStamper.Close();
             pdfReader.Close();
             Console.Read();
             //解析文本
             //PdfReaderContentParser parser = new PdfReaderContentParser(pdfReader);             //PdfWriter pdfWriter;             //ITextExtractionStrategy strategy;
             //strategy = parser.ProcessContent<SimpleTextExtractionStrategy>(1, new SimpleTextExtractionStrategy());
             //string ss = strategy.GetResultantText();             //byte[] buffer = pdfReader.GetPageContent(1);             //string strBody = System.Text.Encoding.Default.GetString(buffer);
         }
     }
