将多个文档与Word.Application(COM interop)组合会导致格式错误?

标签: ms-word office-interop

使用.net 4.0 / vs2010,office 2007

请注意,我可以使用任何其他方法来完成最终结果。我没有和Word结婚,但我确实有限制,不能包含任何许可的第三方工具(没有Aspose),我想尽量减少用户机器上的任何安装。这是一个企业环境,所以我确实有一些控制权。

我需要将2或3个单词的文档打印为单个文档。我的代码如下,它的工作原理....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)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页。

我在哪里失败?方法KillCom(对象o)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>();

我使用 PasteAndFormat 功能来保留原始格式,还复制页面属性以保留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;
    }
