What kind of "values", what kind of Content-Type should the request body
have?

If you simply want to POST some name=value pairs as
application/x-www-form-urlencoded contents then it might be easier to
use WebClient and its UploadValues method:
<http://msdn.microsoft. com/library/default.asp?url =/library/en-us/cpref/html/frlrfSystemNetW ebClientClassUp loadValuesTopic .asp>

If you want to do that with HttpWebRequest then get hold of the request
stream, construct the request body (i.e. name=value pairs encoded as
application/x-www-form-urlencoded) and write it to the request stream.
To urlencode the name and values you can use UrlEncode method of
HttpUtitity.

That's what WebClient.Uploa dValues() will do.
