If you are using .Net 4.0 (or less):

class BetterWebClient : WebClient
{
        private WebRequest _Request = null;

        protected override WebRequest GetWebRequest(Uri address)
        {
            this._Request = base.GetWebRequest(address);

            if (this._Request is HttpWebRequest)
            {
                ((HttpWebRequest)this._Request).AllowAutoRedirect = false;
            }

            return this._Request;
        } 

        public HttpStatusCode StatusCode()
        {
            HttpStatusCode result;

            if (this._Request == null)
            {
                throw (new InvalidOperationException("Unable to retrieve the status 
                       code, maybe you haven't made a request yet."));
            }

            HttpWebResponse response = base.GetWebResponse(this._Request) 
                                       as HttpWebResponse;

            if (response != null)
            {
                result = response.StatusCode;
            }
            else
            {
                throw (new InvalidOperationException("Unable to retrieve the status 
                       code, maybe you haven't made a request yet."));
            }

            return result;
        }
    }

If you are using .Net 4.5.X or newer, switch to HttpClient:

var response = await client.GetAsync("http://www.contoso.com/");
var statusCode = response.StatusCode;
