Code example for file upload mechanism

Hi at all,

first: great project - absolutely!
i have a first question here, maybe someone can give me a hint or example?

I would like to compile a vb-project (MS Visual Studio 2015) with (besides other features) the ability to automatically upload a csv-file to my nextcloud box (NC 13, Ubuntu 16.04 LTS, Apache2).

something like: collect data at a windows pc, convert the data into a csv-file, upload this file with compiled-in https-url/username/password combination fully automatic to my nc-box.

Is there an example for me or are there any ideas, how i can manage this?

Thanks in advance for every help!
