Adding Authorization Header to Web Reference

I'm attempting to make requests to a client's web service (I don't know the underlying platform at the client). I've consumed the client's WSDL in Visual Studio 2010 using "Add Web Reference" and generated my proxy class (called "ContactService").

I now need to add an authorization header like the one below to my service request.

Header=Authorization & Value=Basic 12345678901234567890

(the "123456..." value above is just placeholder)

ContactService service = new ContactService();

//not sure if this is the right way - it's not working
WebClient client = new WebClient();
client.Headers.Add("Authorization", "Basic 12345678901234567890");
service.Credentials = client.Credentials;

int contactKey = null;
contactKey = service.CreateContact("ABC", emailAddress, firstName, lastName, null);

What is the proper way of adding the authorization header to the service request?

Thank you!


The above response was on the right track, but it just had to be in a different location.

I added this to my web reference proxy class that .Net generated:

protected override WebRequest GetWebRequest(Uri uri)
        HttpWebRequest req = (HttpWebRequest)base.GetWebRequest(uri);            
                "Basic " + "12345678901234567890");

        return req;

A Web Reference proxy class extends System.Web.Services.Protocols.SoapHttpClientProtocol. This class contains a call to System.Net.WebRequest.GetWebRequest(Uri uri). A WebRequest allow us to set specific headers on the request when the proxy class' methods are invoked.

Thanks for your help!
