Upload string?

Hi All,
I am a new user to Kaltura, but we are moving to the service for our video needs and was charged with making the lecture capture software I wrote work with Kaltura. The software I wrote automates recordings so professors don't need to do anything other than tell us which classes need to be recorded so we are really trying to automate as much of this process as possible. So my question is whether or not uploading files can be done from within a C# application (not website). I saw somewhere that uploading could be done via a long html string, but can't seem to find that information again. Can this be done from within an application and where can I get full information on this. Thanks.
