c# - How to read metadata information from docx documents?

Question

what I need to achieve is to have a word document template(docx), which will contain Title, Author name, Date, etc.

This template then will be used by users to complete it. I need to create a c# program, that will take in the docx file and read all the information of interest(title, name, date, ..).

So my questions are:

1. How do I put the metadata into the template saying: this is Title, this is Date, this is Name, etc? (not programatically)

2. How do I programmatically read that information?

Answer 1

One way to approach this would be to use Content Controls. In Office, you can create your template, and then for each of your respective inputs of interest you can place one of these controls. They're under the Developer tab in Office.

After inserting your controls you'll need for each of them to have a unique name. Office will let them all have the same name, but you'll need to uniquely identify all of them in your template document.

You now need to get the data that's input in to these controls. Again, there's likely to be some better solutions but Eric White has all kinds of great OpenXML stuff, and so here's one of his: Iterating over Content Controls

I think there's problems with finding content controls nested within a table. So, if you do that, then I think you have to specifically loop over the elements of the table to find content controls within.

Also, you're probably going to want to save a .docx from your .doct file, which I don't think there's any built-in "one-liner" method in OpenXML; however, you can create a new Word document, and then write the file stream of the template in to the newly created docx file. Again, of course, there may be better solutions out there.
