Response.Write("Size of page 1 of " + n + "  => " + width + " × " + height + "");

// file properties
Dictionary<string, string> infodict = reader.Info;
foreach (KeyValuePair<string, string> kvp in infodict)

//Console.WriteLine(kvp.Key + " => " + kvp.Value);

OK, let's say I have a PDF document called "Form.pdf" with 4 form fields. The form fileds are "name", "address", "postal_code" and "email".

Here's the code to create a new PDF file using "Form.pdf" as a template:

private void fillForm()
{
    string formFile = @"N:\.NET\Form.pdf";
    string newFile = @"N:\.NET\Filled-out Form.pdf";
    PdfReader reader = new PdfReader(form File);
    PdfStamper stamper = new PdfStamper(reader, new FileStream(
    newFile, FileMode.Create));
    AcroFields fields = stamper.AcroFields;
 
    // set form fields
    fields.SetField("name", "John Doe");
    fields.SetField("address", "2 Milky Way, London");
    fields.SetField("postal_code", "XX1 4YY");
    fields.SetField("email", "[email protected]"); 
    // flatten form fields and close document
}

Output looks like
