我正在编写一个Web服务,并且想将.docx或.doc更改为.xps。我正在使用Office com来帮助我保存为.xps格式,如下所示:

        [WebMethod]
    public string GetDocPreviewUrl(string m_userName, string m_orgFileName)
    {
        string m_returnUrl = "";

        string m_orgFilePath = _currentDirectory + "\\" + m_userName + "\\" + m_orgFileName;
        if (File.Exists(m_orgFilePath))
        {
            string m_xpsFilePath = _currentDirectory + "\\" + m_userName + "\\" +
                                   Path.GetFileNameWithoutExtension(m_orgFileName) + ".xps";

            OfficeToXpsConversionResult m_converstionResult = OfficeToXps.ConvertToXps(m_orgFilePath, ref m_xpsFilePath);

            m_returnUrl = _baseUrl + m_userName + "/"+ Path.GetFileName(m_xpsFilePath);
        }
        return m_returnUrl;
    }

       private static OfficeToXpsConversionResult ConvertFromWord(string sourceFilePath, ref string resultFilePath)
    {
        object pSourceDocPath = sourceFilePath;

        string pExportFilePath = string.IsNullOrWhiteSpace(resultFilePath) ? GetTempXpsFilePath() : resultFilePath;


        Word.Application() wordApplication = new Word.Application();

        //wordDocument = wordApplication.Documents.Open(ref pSourceDocPath);
        dynamic wordDocument = wordApplication.Documents.Add(pSourceDocPath);

                //return new OfficeToXpsConversionResult(ConversionResult.ErrorUnableToOpenOfficeFile, exc.Message, exc);

        if (wordDocument != null)
        {
            wordDocument.SaveAs(pExportFilePath, WdSaveFormat.wdFormatXPS);
        }

        resultFilePath = pExportFilePath;

        return new OfficeToXpsConversionResult(ConversionResult.OK, pExportFilePath);
    }


但是,当我尝试通过Web方法调用时,出现异常:


  System.Runtime.InteropServices.COMException:Word发生问题。
     在System.Dynamic.ComRuntimeHelpers.CheckThrowException(Int32 hresult,ExcepInfo&excepInfo,UInt32 argErr,String消息)
     在CallSite.Target(Closure,CallSite,ComObject,Object)

在WPF项目中,使用office保存为xps的代码运行良好。如何在asp.net 4.0 Web服务中使用它?谢谢。

最佳答案

从Windows Service(例如IIS和ASP.NET)使用自动化是NOT supported by MS

根据您的需要,您可以为此使用一些库(免费或商业):


来自MS的OpenXML 2.0
Aspose.Words(商业)
VeryDoc.DOCX2XPS(商业)
