Consuming WebServices using HttpWebRequest class

[Baccarin]

Hi,

Did anyone try to consume a WebService using
HttpWebRequest class? I'm getting error 500 using the
following syntax:

req = (HttpWebRequest)WebRequest.Create
("http://IP/vdir/<web service>.asmx/<my method>");

The problem (I believe) is that HttpWebRequest can't
understand correctly the syntax above, or I need to set
some properties that I don't know.

Any help will be useful.

Regards,

Baccarin.
