How to merge documents in C# and VB.Net

Document .Net can help you to merge documents of different formats: PDF, DOCX, RTF, Text and HTML, etc.

For example: You can combine files of the same format!

This's a simple code, how to merge example.pdf and example.docx into a single DOCX document.

using System.IO;

        static void Main(string[] args)

            string[] supportedFiles = new string[] { @"..\..\example.docx", @"..\..\example.pdf" };

            // Create single document.
            DocumentCore dcSingle = new DocumentCore();

            foreach (string file in supportedFiles)

                DocumentCore dc = DocumentCore.Load(file);

                Console.WriteLine("Adding: {0}...", Path.GetFileName(file));

                // Create import session.
                ImportSession session = new ImportSession(dc, dcSingle, StyleImportingMode.KeepSourceFormatting);

                // Loop through all sections in the source document.

                    // This adjusts any document-specific references to styles, bookmarks, etc.
                    //
                    // Importing a element creates a copy of the original element, but the copy
                    // is ready to be inserted into the destination document.
                    Section importedSection = dcSingle.Import<Section>(sourceSection, true, session);

                    // First section start from new page.
                    if (dc.Sections.IndexOf(sourceSection) == 0)
                        importedSection.PageSetup.SectionStart = SectionStart.NewPage;

                    // Now the new section can be appended to the destination document.
                    dcSingle.Sections.Add(importedSection);
