用doc.SaveAs不知道行不,你可以试一试
public static void ConvertToHtml(string docPath, string htmlPath)
{
Word.Application app = new Word.Application();
app.Visible = false;
object o = Type.Missing;
object docFile = docPath;
object readOnly = true;
object fileName = htmlPath;
/*office 2003 begin
Word.Document doc = app.Documents.Open(ref docFile, ref o,ref readOnly, ref o, ref o, ref o, ref o, ref o, ref o, ref o, ref o, ref o, ref o, ref o, ref o, ref o);
object format = Word.WdSaveFormat.wdFormatFilteredHTML;
doc.SaveAs(ref fileName, ref format, ref o, ref o, ref o, ref o, ref o, ref o, ref o, ref o, ref o, ref o, ref o, ref o, ref o,ref o);
//office 2003 end*/
//* offic 2000 begin
Word.Document doc = app.Documents.Open(ref docFile, ref o,ref readOnly, ref o, ref o, ref o, ref o, ref o, ref o, ref o, ref o, ref o);
object format = Word.WdSaveFormat.wdFormatHTML;
doc.SaveAs(ref fileName, ref format, ref o, ref o, ref o, ref o, ref o, ref o, ref o, ref o, ref o);
//*/
doc.Close(ref o,ref o,ref o);
object t = true;
app.Quit(ref t, ref o, ref o);
}
