将word.doc保存到内存流中

Question

我正在尝试将本地文件保存到内存流中，但是我遇到了使代码生效的问题。我尝试通过将文件保存到内存流来完成此操作，但没有运气。 Word.Document只允许通过其方法传递对象类型，因此我无法使用Word.Document.saveas方法保存文档。以下是代码：

  string getAttachment(string path)
    {
        string docname = path;
        string[] sl = docname.Split('.');
        string name = sl[0];
        object missing = Type.Missing;
        string doc = @"...\articles\" + name + ".docx";
        object source = doc;
        object format = Microsoft.Office.Interop.Word.WdSaveFormat.wdFormatDocumentDefault;

        //Word.Document worddoc = new Word.Document();

        MemoryStream outStream = new MemoryStream();


        FileStream outdoc = new FileStream();

        object stream;
        worddoc.SaveAs(outdoc, ref format, ref missing, ref missing, ref missing, ref missing,
                      ref missing, ref missing, ref missing, ref missing, ref missing, ref missing,
                      ref missing, ref missing, ref missing, ref missing);


        outStream = stream.ToString();

        byte[] wordbytes = outStream.ToArray();

        // Convert byte[] to Base64 String
        string base64String = Convert.ToBase64String(wordbytes);
        return base64String;
    }
