Hi
Thanks for your inquiry. You can use Document.AppendDocument method to achieve this. Please see the following code:
// Open source and destination documents.
Document dst = new Document(@"Test001\dst.doc");
Document src = new Document(@"Test001\src.doc");
dst.AppendDocument(src, ImportFormatMode.UseDestinationStyles);
dst.Save(@"Test001\out.doc");
Hope this helps.
Best regards.
