使用.net 4.0/vs2010，office 2007

请注意，我愿意接受任何其他方法来完成最终结果。我没有嫁给 Word，但我确实有不能包含任何许可的第三方工具（没有 Aspose）的限制，我想尽量减少用户机器上的任何安装。这是一个公司环境，所以我确实有一些控制权。

我需要将 2 或 3 个 word 文档打印为单个文档。我的代码如下，它可以工作....除了第二个文档的格式总是有点偏离（段落间距、字体、边距）。奇怪的是第三个文档（它有不同的页面方向）出来很好。有时用户需要将文档发送到传真服务器，因此第一页将是传真封面。

我哪里失败了？？KillCom(object o) 方法调用 System.Runtime.InteropServices.Marshal.ReleaseComObject(o);

 public void CombineMultipleDocuments(string coverSheetPath, string[] documentPaths, string destinationFile, bool makeVisible)
        {
            List<string> docs = new List<string>();

            if (string.IsNullOrWhiteSpace(destinationFile))
                throw new ArgumentException("The destinationfile is required");
            try
            {
                //strip invalid paths
                foreach (string p in documentPaths)
                {
                    if (!string.IsNullOrWhiteSpace(p) && File.Exists(p))
                    {

我使用PasteAndFormat函数来保持原始格式，并复制页面属性以保持每个文档的边距和方向。

 void mergeDocumentsTest(List<string> documentFiles)
 {

        _Application oWord = new Microsoft.Office.Interop.Word.Application();
        _Document oDoc = oWord.Documents.Add();
        Selection oSelection = oWord.Selection;

        foreach (string documentFile in documentFiles)
        {
            _Document oCurrentDocument = oWord.Documents.Add(documentFile);
            copyPageSetup(oCurrentDocument.PageSetup, oDoc.Sections.Last.PageSetup);
            oCurrentDocument.Range().Copy();
            oSelection.PasteAndFormat(WdRecoveryType.wdFormatOriginalFormatting);
            if (!Object.ReferenceEquals(documentFile, documentFiles.Last()))
                oSelection.InsertBreak(WdBreakType.wdSectionBreakNextPage);
        }

        oDoc.SaveAs("testdoc.doc");
        oDoc.Close();

        //TODO: release objects, close word application

    }

    void copyPageSetup(PageSetup source, PageSetup target)
    {
        target.PaperSize = source.PaperSize;

        //target.Orientation = source.Orientation; //not working in word 2003, so here is another way
        if (!source.Orientation.Equals(target.Orientation))
            target.TogglePortrait();

        target.TopMargin = source.TopMargin;
        target.BottomMargin = source.BottomMargin;
        target.RightMargin = source.RightMargin;
        target.LeftMargin = source.LeftMargin;
        target.FooterDistance = source.FooterDistance;
        target.HeaderDistance = source.HeaderDistance;
        target.LayoutMode = source.LayoutMode;
    }
