使用 Office 2010 COM 的 asp.net Web 服务
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帮助我另存为.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,当我尝试通过网络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,字符串消息) 在CallSite.Target(闭包,CallSite,ComObject,对象) 在 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 C:\Users\Icicle\Documents\Fotomax WP7\DocProcessService\DocProcessService\OfficeHelper\OfficeToXps.cs 中的 DocProcessService.OfficeToXps.ConvertFromWord(String sourceFilePath, String& resultFilePath):第 145 行 在 C:\Users\Icicle\Documents\Fotomax WP7\DocProcessService\DocProcessService\OfficeHelper\OfficeToXps.cs 中的 DocProcessService.OfficeToXps.ConvertToXps(String sourceFilePath, String& resultFilePath):第 63 行 在 C:\Users\Icicle\Documents\Fotomax WP7\DocProcessService\DocProcessService\DocDownload.asmx.cs 中的 DocProcessService.DocDownload.GetDocPreviewUrl(String m_userName, String m_orgFileName):第 90 行
使用 Office 另存为 xps 的代码运行良好在我的 WPF 项目中。如何在我的 ASP.NET 4.0 Web 服务中使用它?谢谢。
I am writing a web service and would like to change the .docx or .doc to .xps. I'm using office com to help me to save as .xps format as following:
[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);
}
However, I got exception when I try to call by the web method:
System.Runtime.InteropServices.COMException: Word 發生問題。

The code of using office to save as xps was working well in my WPF project. How can I make use it in my asp.net 4.0 web service? Thanks.

从 Windows 服务(例如 IIS 和 ASP.NET)使用自动化是 微软不支持!
根据您的需要,您可以使用一些库(免费或商业)来实现此目的:
Using Automation from Windows Service (IIS and ASP.NET for example) is NOT supported by MS !
Depending on what you need you can use some library (free or commercial) for this:
