You can try this

C#

using System.IO;
using iTextSharp;
using iTextSharp.text;
using iTextSharp.text.pdf;

using (MemoryStream myMemoryStream = new MemoryStream())
            {
                Document myDocument = new Document();
                PdfWriter myPDFWriter = PdfWriter.GetInstance(myDocument, myMemoryStream);
 
                myDocument.Open();
 
                // Add to content to your PDF here... 
                PdfPTable table = new PdfPTable(2);
                PdfPCell header = new PdfPCell(new Phrase("Your Heading"));
                header.Colspan = 2;
                header.HorizontalAlignment = 1; //0=Left, 1=Centre, 2=Right
                table.AddCell(header);
                table.AddCell("ID:" + Textbox1.Text);  //Your textboxes
                myDocument.Add(table);
                myDocument.Close();
 
                byte[] content = myMemoryStream.ToArray();
 
          // Write out PDF from memory stream. 
          using (FileStream fs = File.Create("C:\\Test.pdf")) //Your pdf file
                {
                    fs.Write(content, 0, (int)content.Length);
                }
            }

On the form you want to view the PDf, you can write the following on the Load event of the Form

C#

private string strFilename = "";

strFilename = @"C:\aTestFile.pdf";
axAcroPDF1.src = strFilename;

//I used a Adobe PDF Reader component from the toolbox that you need to add. You can get it from the COM components-Adobe PDF Reader

            ReadPdf("D:\\", strings);

            {
                Console.WriteLine("Reading Pdf file.....");
                PdfDocument outputPDFDocument = new PdfDocument();

                foreach (string pdfFile in pdfFiles)
                {
                    PdfDocument inputPDFDocument = PdfReader.Open(pdfFile, PdfDocumentOpenMode.Import);
                    outputPDFDocument.Version = inputPDFDocument.Version;
                    foreach (PdfPage page in inputPDFDocument.Pages)
                    {
                        outputPDFDocument.AddPage(page);
                    }
                }
                outputPDFDocument.Save(outputFilePath);
                Console.WriteLine("Successfully Completed the pdf documents");
                Console.WriteLine("File path is: {0}", MergedFileresultspath);
                Console.ReadLine();
            }
            else
                Console.WriteLine("Please Give the pdf file path before read & save");

What do you mean by read the PDF file? I'm not kidding asking this question because it's important to understand that a PDF file isn't a structured file. In other words, you can't say that you can retrieve a paragraph, for instance, just by reading some strings. Plus, do you want to consider image data in this as well? About the best that you can do is something like this:

C#

public string ParsePdf(string fileName)
{
  if (!File.Exists(fileName))
    throw new FileNotFoundException("fileName");
  using (PdfReader reader = new PdfReader(fileName))
  {
    StringBuilder sb = new StringBuilder();

    ITextExtractionStrategy strategy = new SimpleTextExtractionStrategy();
    for (int page = 0; page < reader.NumberOfPages; page++)
    {
      string text = PdfTextExtractor.GetTextFromPage(reader, page + 1, strategy);
      if (!string.IsNullOrWhitespace(text))
      {
        sb.Append(Encoding.UTF8.GetString(ASCIIEncoding.Convert(Encoding.Default, Encoding.UTF8, Encoding.Default.GetBytes(text))));
      }
    }

    return sb.ToString();
  } 
 }
}

This uses a simple reader provided by ITextSharp to read the text out. There's no attempt to create anything like paragraphs out of this.
