Merge Multiple Word Documents in C# With Same Format

This method is capable of merging multiple Word files into one document

  //Load Document1 and Document2
  Document DocOne = new Document();
  DocOne.LoadFromFile(@"E:\Work\Document\welcome.docx", FileFormat.Docx);
  Document DocTwo = new Document();
  DocTwo.LoadFromFile(@"E:\Work\Document\New Zealand.docx", FileFormat.Docx);

  //Merge
  foreach (Section sec in DocTwo.Sections)
  {
  DocOne.Sections.Add(sec.Clone());
  }

  //Save and Launch
  DocOne.SaveToFile("Merge.docx", FileFormat.Docx);
 

By doing so, you must add C# Word component as a reference in project.
As for the format, you need use ParagraphFromat Object to copy format from one paragraph
to another, this post may be helpful

Hi, I'm not sure what your template files look like. I mean does the content of those importing files have a direct formatting or does it use some style.

In a case they have only style formatting applied to them then you can control whether you want the content to use source document's style or a destination document's style.

For example here is something that you can try:

DocumentModel doc = DocumentModel.Load("E:\\MergeTemplates\\Temp.doc");
string[] newDocPaths = { "E:\\MergeTemplates\\Template1.doc",
                            "E:\\MergeTemplates\\Template2.doc",
                            "E:\\MergeTemplates\\Template3.doc"};
 
foreach (DocumentModel newDoc in newDocPaths.Select(path => DocumentModel.Load(path)))
    foreach (Section newDocSection in newDoc.Sections)
        // Last bool parameter indicates whether to use destination styles if 'true'
        // or not to use them if 'false'. 
        doc.Sections.Add(doc.Import(newDocSection, true, false));
 
doc.Save("E:\\MergeTemplates\\Temp.doc");

The code uses a C# component for Word documents, it provides a simple way how you can read and modify your DOC files with C#.
