需要引入的依赖包，在这里我用的是下面两个版本的依赖包
iTextSharp 版本为5.5.13.3
QRCoder 版本为1.4.3
生成的效果
以下是核心代码
PdfUtils类
public class PdfUtils
{
const string ITextExamplesFolder = "iTextExamples";
const string ResourcesFolder = "resources";
public static string Author => "haogm";
public static string GetBaseDir()
{
return Environment.CurrentDirectory;
}

public static void CreateCell(PdfPTable table, string content, Font font, int minimumHeight = 20, int colspan = 0, int rowspan = 0)
{
var cell = new PdfPCell(new Phrase(content, font));
cell.UseAscender = true;// 设置可以居中
cell.MinimumHeight = minimumHeight;// 设置单元格高度
cell.HorizontalAlignment = PdfPCell.ALIGN_CENTER;// 设置水平居中
cell.VerticalAlignment = PdfPCell.ALIGN_MIDDLE;// 设置垂直居中
if (rowspan != 0)
{
cell.Rowspan = rowspan; //行合并
}
if (colspan != 0)
{
cell.Colspan = colspan; //列合并
}
table.AddCell(cell);
}

}
//生成二维码的路径

{
return Path.Combine(GetOutputFolder(), $"Qr.jpg");
}
public static string GetOutputFolder()
{

public static void VerifyPdfFileIsReadable(byte[] file)
{

try
{

var author = reader.Info["Author"] as string;
if (string.IsNullOrWhiteSpace(author) || !author.Equals(Author))
{
throw new InvalidPdfException("This is not a valid PDF file.");
}
}
finally
{
reader?.Close();
}
}
public static void VerifyPdfFileIsReadable(string filePath)
{

}
}调用PdfUtils类，生成PDF文档
