how to pass basic authentication in webservice?

Question

I have a webservice which has a method to return a value.Here my requirement is , I want to pass the authentication value in header for each and every web request i used the below given code for doing the same

req = WebRequest.Create(http://localhost/test/test.asmx); string _auth = string.Format("{0}:{1}", "username", "password"); string _enc = Convert.ToBase64String(Encoding.ASCII.GetBytes(_auth)); string _cred = string.Format("{0} {1}", "Basic", _enc); req.Headers[HttpRequestHeader.Authorization] = _cred; WebResponse response = (WebResponse)req.GetResponse();

But through this way I am not able to call the webmethod. Is there any way to achieve the same.

Also I tried to sending the authentication values with the help of ICredentials with the following given code , but i need the header values like "Authorization: Basic YWRtaW46YWRtaW4="

 ICredentials creds; creds = new NetworkCredential("username", "password", "domain"); proxy.Credentials = creds; string str=proxy.helloworld();

please let me know if there is any way to achieve this..any help is appreciated.

thanks

Copying from this post.

protected override System.Net.WebRequest GetWebRequest(Uri uri) { HttpWebRequest request; request = (HttpWebRequest)base.GetWebRequest(uri); if (PreAuthenticate) { NetworkCredential networkCredentials = Credentials.GetCredential(uri, “Basic”); if (networkCredentials != null) { byte[] credentialBuffer = new UTF8Encoding().GetBytes( networkCredentials.UserName + “:” + networkCredentials.Password); request.Headers["Authorization"] = “Basic” + Convert.ToBase64String(credentialBuffer); } else { throw new ApplicationException(“No network credentials”); } } return request; }
