How to get status code from webclient?

Question

I am using the WebClient class to post some data to a web form. I would like to get the response status code of the form submission. So far I\'ve found out how

Answer 1

This is what I use for expanding WebClient functionality. StatusCode and StatusDescription will always contain the most recent response code/description.

                /// 

                /// An expanded web client that allows certificate auth and 
                /// the retrieval of status' for successful requests
                /// 
                public class WebClientCert : WebClient
                {
                    private X509Certificate2 _cert;
                    public WebClientCert(X509Certificate2 cert) : base() { _cert = cert; }
                    protected override WebRequest GetWebRequest(Uri address)
                    {
                        HttpWebRequest request = (HttpWebRequest)base.GetWebRequest(address);
                        if (_cert != null) { request.ClientCertificates.Add(_cert); }
                        return request;
                    }
                    protected override WebResponse GetWebResponse(WebRequest request)
                    {
                        WebResponse response = null;
                        response = base.GetWebResponse(request);
                        HttpWebResponse baseResponse = response as HttpWebResponse;
                        StatusCode = baseResponse.StatusCode;
                        StatusDescription = baseResponse.StatusDescription;
                        return response;
                    }
                    /// 

                    /// The most recent response statusCode
                    /// 
                    public HttpStatusCode StatusCode { get; set; }
                    /// 

                    /// The most recent response statusDescription
                    /// 
                    public string StatusDescription { get; set; }
                }

Thus you can do a post and get result via:

            byte[] response = null;
            using (WebClientCert client = new WebClientCert())
            {
                response = client.UploadValues(postUri, PostFields);
                HttpStatusCode code = client.StatusCode;
                string description = client.StatusDescription;
                //Use this information
            }
