c# - How to set the revision Number to a file -

-

i using file upload in project. set revision number file uploading in database. i.e. upload sd.doc file first time saved version 1. after downloading file make changes , save should saved version 2. while viewing should show both version , should choose file based on version. can 1 me solve issue.

thanks in advance.

if right understand problem, need versioning system docs. 1 of solutions can think off, using of mercurial dvs. can create simple ui interafce interact it's command line "hg". provides huge potential, probabbly no need in app, saving "revision" number, enable others query it, done + given huge amount of options future development.

but depends on project requirements. keep eye on , make choice.

hope helps.

regards.
