word file raw data from word document object?

[FlyingBear]

is there a way to get the raw data of a word file document object?

word = new Word.Application();
doc = new Word.Document();

now, I open the word file, do some replace. save the file.

I could open the file as raw binary file. but I'm thinking maybe there is a property that can get the raw the data? which property?


thanks
