Please help me to convert .doc file to .docx using open xml sdk or any other method except word automation.
Thanks in advance.
回答1:
The OpenXML SDK allows you to manipulate only .docx files, not .doc. Here's a blog post illustrating how to perform bulk conversions of .doc to .docx files using a bulk conversion utility. I am afraid that if you don't want to use Word Automation, you will have to write your own .doc parser which might be quite a work.

I haven't used it, but take a look at http://b2xtranslator.sourceforge.net/.
In addition, if your scenario supports it, and if your business needs allow for it, it sometimes is effective to install a copy of SharePoint Server 2010, and use Word Automation Services. Some people install a copy of SharePoint Server 2010 just to run Word Automation Services. Word Automation Services has the capability of doing unattended server-side conversion of DOC to DOCX.
Depending on your scenario, Word Automation can be very troublesome. In addition, if you are using Word Automation to serve specific functionality to a set of customers, then there may be licensing considerations. Note that Word Automation is a different technology from Word Automation Services.
