我正在编写一个Web服务,并希望将.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:

        [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,当我尝试通过网络方法调用时,我遇到了异常:

  

System.Runtime.InteropServices.COMException:Word发生问题。      在System.Dynamic.ComRuntimeHelpers.CheckThrowException(Int32 hresult,ExcepInfo& excepInfo,UInt32 argErr,String message)      在CallSite.Target(Closure,CallSite,ComObject,Object)      在System.Dynamic.UpdateDelegates.UpdateAndExecute2 [T0,T1,TRet](CallSite站点,T0 arg0,T1 arg1)      在CallSite.Target(Closure,CallSite,Object,Object)      在System.Dynamic.UpdateDelegates.UpdateAndExecute2 [T0,T1,TRet](CallSite站点,T0 arg0,T1 arg1)      at DocProcessService.OfficeToXps.ConvertFromWord(String sourceFilePath,String& resultFilePath)在C:\ Users \ Icicle \ Documents \ Fotomax WP7 \ DocProcessService \ DocProcessService \ OfficeHelper \ OfficeToXps.cs:第145行      at DocProcessService.OfficeToXps.ConvertToXps(String sourceFilePath,String& resultFilePath)在C:\ Users \ Icicle \ Documents \ Fotomax WP7 \ DocProcessService \ DocProcessService \ OfficeHelper \ OfficeToXps.cs:第63行      at DocProcessService.DocDownload.GetDocPreviewUrl(String m_userName,String m_orgFileName)在C:\ Users \ Icicle \ Documents \ Fotomax WP7 \ DocProcessService \ DocProcessService \ DocDownload.asmx.cs:第90行

使用office保存为xps的代码在我的WPF项目中运行良好。如何在我的asp.net 4.0 Web服务中使用它?感谢。

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

根据您的需要,您可以使用一些库(免费或商业):
