I have had a similar problem, but I also needed to use a username and password for the proxy that differ from the username and password used to access the service.

I tried building it up through a UriBuilder, which would output the proxy address as "http://username:password@myproxyserver/". Unfortunately, the particular proxy I was using didn't work with this technique.

What I found after extensive Googling, is that you can change the proxy through WebRequest.DefaultProxy (static property).

For example:

WebProxy proxy = new WebProxy("http://myproxyserver",true);
proxy.Credentials = new NetworkCredential("username", "password");
WebRequest.DefaultWebProxy = proxy;
