I have an article with some tips on using WebClient and WebRequest to
post data, though it doesn't deal with file upload specifically:
http://odetocode.com/Articles/162.aspx

The article references a tool "Fiddler", which is an Http Debugging
Proxy and a great way to see "how your browser does it".

HTH,

I think you're asking whether you can automatically upload a file, without
the user interaction. The short answer is no, you can't. It would be a huge
security hole into the system. You will have to install an ActiveX control
(and be careful, .Net user controls will not help you here as they are
hosted in a secure environment) that would read the file and upload it. But
then again, unless you do it really well (as in only upload to a known host
name, over SSL) you will open a security hole into whoever installs the
control.

There's no "simple way" -- what you want is a proper implementation of
http://www.faqs.org/rfcs/rfc2388.html, based on
HttpWebRequest/HttpWebResponse. WebClient.UploadFile() should have been
that, but has a bug that may cause some server-side upload facilities (like
PHP) to fail.

Cheers,
