c# - 使用 DocumentFormat.OpenXml(c#) 合并 word 文档

Question

DocumentFormat.OpenXML考虑到 MS Word“跟踪更改”的模式，有什么方法可以使用 library 合并 2 个 word-documents 。或者也许可以使用另一个库？

Answer 1

You can use standart api of MS Word

    Microsoft.Office.Interop.Word.Document worddoc;
    Microsoft.Office.Interop.Word.Application wordApp;
    Microsoft.Office.Interop.Word.Range _range;              
    object file = "1.doc";
    wordApp = new Microsoft.Office.Interop.Word.Application();
    worddoc = wordApp.Documents.Open(ref file); 
    _range = worddoc.Content;
    Microsoft.Office.Interop.Word.Range rng = _range; 
    rng.Start = rng.End;
    rng.InsertFile("2.doc");

EDIT

And read this Merging-Word-Documents

EDIT2

so try this

    using DocumentFormat.OpenXml.Packaging;
    using DocumentFormat.OpenXml.Wordprocessing;
    ....
    public byte[] OpenAndCombine(List<string> FileNames)
    {
        List<byte[]> documents = new List<byte[]>();
        foreach (string _FileName in FileNames)               
                documents.Add(File.ReadAllBytes(_FileName));

        MemoryStream mainStream = new MemoryStream();

        mainStream.Write(documents[0], 0, documents[0].Length);
        mainStream.Position = 0;

        int pointer = 1;
        byte[] ret;
            using (WordprocessingDocument mainDocument = WordprocessingDocument.Open(mainStream, true))
            {

                XElement newBody = XElement.Parse(mainDocument.MainDocumentPart.Document.Body.OuterXml);

                for (pointer = 1; pointer < documents.Count; pointer++)
                {
                    WordprocessingDocument tempDocument = WordprocessingDocument.Open(new MemoryStream(documents[pointer]), true);
                    XElement tempBody = XElement.Parse(tempDocument.MainDocumentPart.Document.Body.OuterXml);

                    newBody.Add(tempBody);
                    mainDocument.MainDocumentPart.Document.Body = new Body(newBody.ToString());
                    mainDocument.MainDocumentPart.Document.Save();
                    mainDocument.Package.Flush();
                }
            }
            ret = mainStream.ToArray();
            mainStream.Close();
            mainStream.Dispose();
        return (ret);
    }
