Hello,

Thanks for your inquiry.
To facilitate problem reproduction, please provide us with your source PDF document(If it's not convenient, you can provide us with a simplified version of the document). Also, since your provided code contains many other classes and parameters that we cannot simulate, could you kindly provide a simple demo for us to test? You could attach them here or send them to us via email (support@e-iceblue.com). Thanks in advance.

Sincerely

Hi,

Thanks for sharing the information via email.
I tested your sample code and did reproduce the issue you mentioned. After investigation, we found that most of the text box fields in your source PDF document were not filled with values. We tested your document using the code below, and the result indicated that we could correctly retrieve the values of text box fields that had been filled with text. We suggest that you use the latest version of Spire.PDF(Spire.PDF Pack(Hot Fix) Version:9.6.0) for testing first. Looking forward to your test feedback.

Code: Select all

            StringBuilder sb = new StringBuilder();
            string input = "Sample.pdf";
            PdfDocument doc = new PdfDocument();
            doc.LoadFromFile(input);
            //Get PDF Form Object
            PdfFormWidget formWidget = doc.Form as PdfFormWidget;
            //traversal
            for (int i = 0; i < formWidget.FieldsWidget.List.Count; i++)
            {
                PdfField field = formWidget.FieldsWidget.List[i] as PdfField;
                //Check whether the specified form field is a text box
                if (field is PdfTextBoxFieldWidget)
                {
                    PdfTextBoxFieldWidget textBoxField = field as PdfTextBoxFieldWidget;
                    //Get text of textbox
                    string text = textBoxField.Text;
                    sb.Append(textBoxField.Name+" ====> " + text + "\r\n");
                }
            }
            //Write all fields and their values in the source document to a text document
            string result = "result.txt";
            File.WriteAllText(result, sb.ToString());
