Fill a PDF form using C# console application

Fill a PDF form using C# console application

We will be using the SyncFusion Package to fill out the PDF Form Fields. To add SyncFusion to your project follow these steps :

1. Go to Tool -> NuGet Package Manager -> Manage NuGet Packages For Solution
2. Then search Syncfusion.Pdf.WinForms and install it.

Steps to be followed to fill the PDF form fields :

1) Save the PDF File in the project
2) Include the namespaces in the Program.cs

using Syncfusion.Pdf;
using Syncfusion.Pdf.Graphics;
using Syncfusion.Pdf.Parsing;
using Syncfusion.Pdf.Security;
using System.Drawing;

3) Load the PDF Document

PdfLoadedDocument loadedDocument = new   PdfLoadedDocument(“PdfName.pdf”);

4) Get the first page of the document

PdfLoadedPage page = loadedDocument.Pages[0] as PdfLoadedPage;

5) Get the loaded form

PdfLoadedForm form = loadedDocument.Form;

6) Fill the fields from the first page

form.Fields["Name"] as PdfLoadedTextBoxField).Text = "Raman";

7) Save the document

loadedDocument.Save(“PdfName.pdf”);

8) Close the document

loadedDocument.Close(true);

9) Open the PDF file so that the result will be seen in default PDF viewer

 Process.Start("Form.pdf");
