Hi!

I am a bit lost. I want to upload multiple files and key-value pairs via
HTTP post.

A single file and a single collection of key-value pairs is easy. You just
have to use the System.Net.WebClient class and its UploadFile, UploadValues
method.

Can anyone explain to me how to post both files and values with one request?
I would very much appreciate any hint!

Hey, Lloyd, this is a pretty inactive group. You might try posting to the
C# or VB group. (microsoft.public.dotnet.languages.csharp and the same
with vb instead of csharp -- haven't I seen you there?)

Oh! I didn't realize you cross-posted it. Never mind!

If you need to post data to the server it might be easier to use
HttpWebRequest. I wrote an article and a wrapper class that handles these
aspects easily here a few years back:

http://www.west-wind.com/presentations/dotnetWebRequest/dotnetWebRequest.htm

You can use AddPostFile and AddPostKey in combination with the class to
upload files and form vars.
