I tried using the code in the examples but I get a Null Exception error on
Code:
PdfAcroField.PdfAcroFieldCollection fields = form.Fields; //or document.AcroForm.Fields.Names;
I have also tried the following code but I still return a null exception:
Code:
string fileN4 = TextBox1.Text + " LOG.pdf";
File.Copy(Path.Combine(textBox4.Text + "\\", fileN4),
Path.Combine(Directory.GetCurrentDirectory(), fileN4), true);
// Open the file
PdfDocument document = PdfReader.Open(fileN4, PdfDocumentOpenMode.Modify);
PdfTextField currentField = (PdfTextField)(document.AcroForm.Fields["<CASENUM>"]);
//const
string caseName = TextBox1.Text;
PdfString caseNamePdfStr = new PdfString(caseName);
//set the value of this field
currentField.Value = caseNamePdfStr;
// Save the document...
document.Save(fileN4);
Any help would be great!
