**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**

1     public class ConstantInfo
     2     {
     3         /// <summary>
     4         /// 证书下载目录
     5         /// </summary>
     6         public static string _Certificate { get { return "/DownloadResource/Certificate/"; } }
     7 
     8         /// <summary>
     9         /// 证书模板目录
    10         /// </summary>
    11         public static string _CertificateTemplate { get { return "/Resources/"; } }
    12     }

**三、生成pdf主体代码**

1     class Program
     2     {
     3         static void Main(string[] args)
     4         {
     5             //生成的pdf文件名称
     6             string fileName = "Certificate_test.pdf";
     7             //生成的pdf文件目录
     8             string downloadFilePath = AppDomain.CurrentDomain.BaseDirectory + ConstantInfo._Certificate;
     9             //生成的pdf文件完整路径
    10             string downloadFileName = downloadFilePath + fileName;
    11             //如没有，则创建
    12             if (!Directory.Exists(downloadFilePath))
    13             {
    14                 Directory.CreateDirectory(downloadFilePath);
    15             }
    16             //证书模板目录
    17             string templateFilePath = AppDomain.CurrentDomain.BaseDirectory + ConstantInfo._CertificateTemplate + "TemplateCer.pdf";
    18             //可直接写成固定目录
    19             //string tempFilePath = "D:\\tmp.pdf";
    20             //字体资源
    21             string fontFilePath = AppDomain.CurrentDomain.BaseDirectory + ConstantInfo._CertificateTemplate + "msyhbd.ttf";
    22 
    23 
    24             iTextSharp.text.pdf.PdfReader pdfReader = new iTextSharp.text.pdf.PdfReader(templateFilePath);
    25             PdfStamper pdfStamper = new PdfStamper(pdfReader, new FileStream(downloadFileName, FileMode.OpenOrCreate));
    26             AcroFields pdfFormFields = pdfStamper.AcroFields;
    27             pdfStamper.FormFlattening = true;
    28 
    29             //BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
    30             BaseFont simheiBase = BaseFont.CreateFont(fontFilePath, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
    31 
    32             //添加图片
    33             //Image image = Image.GetInstance("");
    34             //pdfStamper.Writer.Add(image);
    35 
    36             pdfFormFields.AddSubstitutionFont(simheiBase);
    37             //根据pdf中对应的表单域（一定要一致）赋对应的值
    38             pdfStamper.AcroFields.SetField("Name", "小红");
    39             pdfStamper.AcroFields.SetField("Score", "600");
    40             pdfStamper.AcroFields.SetField("CompanyName", "测试测试");
    41             pdfStamper.AcroFields.SetField("Date", "2019-7-17");
    42             //pdfStamper.AcroFields.SetField("chk", "yes", true);
    43             pdfStamper.Close();
    44             pdfReader.Close();
    45             Console.Read();
    46             //解析文本
    47             //PdfReaderContentParser parser = new PdfReaderContentParser(pdfReader);
    48 
    49             //PdfWriter pdfWriter;
    50 
    51             //ITextExtractionStrategy strategy;
    52             //strategy = parser.ProcessContent<SimpleTextExtractionStrategy>(1, new SimpleTextExtractionStrategy());
    53             //string ss = strategy.GetResultantText();
    54 
    55             //byte[] buffer = pdfReader.GetPageContent(1);
    56 
    57             //string strBody = System.Text.Encoding.Default.GetString(buffer);
    58         }
    59     }

**四、文件路径如图：**

**其中ttf是用到的字体，看自己需要用到什么字体，可直接从网上下载对应的字体**

后记:最近遇到一个问题，在软件中已经用预览功能调整好字体的大小，但是在程序中，如果不用下载字体的话，值赋不上，如果用下载的字体（ttf）的话,和在软件中设置的还是有差别的。最后还是得再调整。有时间一定要看看这个问题。
