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 message) at CallSite.Target(Closure , CallSite , ComObject , Object ) at System.Dynamic .UpdateDelegates.UpdateAndExecute2[T0,T1,Tret](CallSite 站点,T0 arg0,T1 arg1)在 CallSite.Target(闭包,CallSite,对象,对象)在 System.Dynamic.UpdateDelegates.UpdateAndExecute2[T0,T1,Tret]( CallSite 站点,T0 arg0,T1 arg1) 在 DocProcessService.OfficeToXps.ConvertFromWord(String sourceFilePath, String& resultFilePath) 在 C:\Users\Icicle\Documents\Fotomax WP7\DocProcessService\DocProcessService\OfficeHelper\OfficeToXps.cs: DocProcessService 的第 145 行。 C 中的 OfficeToXps.ConvertToXps(String sourceFilePath, String& resultFilePath):\Users\Icicle\Documents\Fotomax WP7\DocProcessService\DocProcessService\OfficeHelper\OfficeToXps.cs:C:\Users\Icicle\Documents\Fotomax WP7\DocProcessService\ DocProcessService.DocDownload.GetDocPreviewUrl(String m_userName, String m_orgFileName) 的第 63 行DocProcessService\DocDownload.asmx.cs:第 90 行
使用office另存为xps的代码在我的WPF项目中运行良好。如何在我的 asp.net 4.0 网络服务中使用它?谢谢。
