Copy document content (including formatting and page format) to another using Word Interop in c# with 100% fidelity
I want to copy the content of a document created by the user to an existing document. The existing document content must be an exact mirror to the document created by the user.
I cannot simply copy the file using System.IO or saving a copy of the document created by the user using SaveAs methods in Word Interop. This is because the existing document is a document that is generated from a webserver and has VBA modules for uploading it back to the server.
The document generated by the webserver (existing document) is a Word 2003 document, but the document created by the user is either a Word 2003 document or Word 2007+.
Having these limitations in mind, I first created the following method:
string tempsave = //location of user created document;
string savelocation = //location of existing document;
Word.Application objWordOpen = new Word.Application();
Document doclocal = objWordOpen.Documents.Open(tempsave);
Document d1 = objWordOpen.Documents.Open(savelocation);
Word.Range oRange = doclocal.Content;
oRange.Copy();
d1.Activate();
d1.UpdateStyles();
d1.ActiveWindow.Selection.WholeStory();
d1.ActiveWindow.Selection.PasteAndFormat(Word.WdRecoveryType.wdFormatOriginalFormatting);
This is generally working. However, the tables are messed up.
Also, if there is a Page Break, the output is different.
The user created document:
The output - existing document:
Also, at the end of the document a paragraph mark is added, as follows:
The user created document:
The output - existing document:
The page format is also messed up, the output having mirror margins set up.
The user created document:
The output - existing document:
I have also tried using Range.Insert() method and setting the range without copying as described here https://stackoverflow.com/a/54500605/10468231, but I am still having these issues.
I have also tried adding the VBA modules to the document, but there are also Document Variables and other custom properties and I don't want to mess with the file being uploaded to the server. How do I handle these issues? Both the documents are based on Normal template.
I am open to another suggestion regarding this topic, but I know that .doc files are not handled as easily as .docx format, this is why I think I am stuck with COM Interop.
Thank you.
UPDATE Based on Macropod code posted by Charles Kenyon, I have managed to copy more of the formatting from the source to target. Still, there is the difference at the page break - the paragraph mark is places on the new page, instead on the same page. Also, the text is slightly larger, even though the Font Size is the same.

UPDATE 2
Actually, the page break not remaining in line with paragraph format is not an issue of copying fidelity, but rather an issue of conversion from .doc to .docx. (https://support.microsoft.com/en-us/help/923183/the-layout-of-a-document-that-contains-a-page-break-may-be-different-i) Maybe someone thought of a method to overcome this.
Solution
The following code by Paul Edstein (macropod) may assist you. It will at least give you an idea of the complexities you are facing.

' Users occasionally need to combine multiple documents that may of may not have the same page layouts,
' Style definitions, and so on. Consequently, combining multiple documents is often rather more complex than
' simply copying & pasting content from one document to another. Problems arise when the documents have
' different page layouts, headers, footers, page numbering, bookmarks & cross-references,
' Tables of Contents, Indexes, etc., etc., and especially when those documents have used the same Style
' names with different definitions.
'
' The following Word macro (for Windows PCs only) handles the more common issues that arise when combining
' documents; it does not attempt to resolve conflicts with paragraph auto-numbering,
' document -vs- section page numbering in 'page x of y' numbering schemes, Tables of Contents or Indexing issues.
' Neither does it attempt to deal with the effects on footnote or endnote numbering & positioning or with the
' consequences of duplicated bookmarks (only one of which can exist in the merged document) and any corresponding
' cross-references.
'
' The macro includes a folder browser. Simply select the folder to process and all documents in that folder
' will be combined into the currently-active document. Word's .doc, .docx, and .docm formats will all be processed,
' even if different formats exist in the selected folder.
