问题 Is there a good way to see if two documents are the same using the word interop? I have tried using something like: Word.Document tempDoc = app.CompareDocuments(document1, document2); My issue is that tempDoc is not null if they are the same, so I'm not sure how to use this result to determine whether the documents are the same.
