Tried it out. ResponseHeaders do not include status code.

If I'm not mistaken, <code>WebClient</code> is capable of abstracting away multiple distinct requests in a single method call (e.g. correctly handling 100 Continue responses, redirects, and the like). I suspect that without using <code>HttpWebRequest</code> and <code>HttpWebResponse</code>, a distinct status code may not be available.

It occurs to me that, if you are not interested in intermediate status codes, you can safely assume the final status code is in the 2xx (successful) range, otherwise, the call would not be successful.

The status code unfortunately isn't present in the <code>ResponseHeaders</code> dictionary.

There is a way to do it using reflection. It works with .NET 4.0. It accesses a private field and may not work in other versions of .NET without modifications.

I have no idea why Microsoft did not expose this field with a property.

{
 FieldInfo responseField = client.GetType().GetField("m_WebResponse", BindingFlags.Instance | BindingFlags.NonPublic);

Erik's answer doesn't work on Windows Phone as is. The following does:

<pre><code>class WebClientEx : WebClient
{
 private WebResponse m_Resp = null;

 protected override WebResponse GetWebResponse(WebRequest Req, IAsyncResult ar)
 {
 try
 {
 this.m_Resp = base.GetWebResponse(request);
 }
 catch (WebException ex)
 {
 if (this.m_Resp == null)
 this.m_Resp = ex.Response;
 }
 return this.m_Resp;
 }

 public HttpStatusCode StatusCode
 {
 get
 {
 if (m_Resp != null &amp;&amp; m_Resp is HttpWebResponse)
 return (m_Resp as HttpWebResponse).StatusCode;
 else
 return HttpStatusCode.OK;
 }
 }
}
</code></pre>

At least it does when using <code>OpenReadAsync</code>; for other <code>xxxAsync</code> methods, careful testing would be highly recommended. The framework calls GetWebResponse somewhere along the code path; all one needs to do is capture and cache the response object.

The fallback code is 200 in this snippet because genuine HTTP errors - 500, 404, etc - are reported as exceptions anyway. The purpose of this trick is to capture non-error codes, in my specific case 304 (Not modified). So the fallback assumes that if the status code is somehow unavailable, at least it's a non-erroneous one.

blocks|key|1159669|text|您可以尝试使用此代码从WebException或OpenReadCompletedEventArgs.Error获取HTTP状态代码。它也可以在Silverlight中工作，因为SL没有定义WebExceptionStatus.ProtocolError。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1159670|HttpStatusCode+GetHttpStatusCode(System.Exception+err)

 /// &lt;/summary&gt;
 public class WebClientCert : WebClient
 {

 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;
 }
 /// &lt;summary&gt;
 /// The most recent response statusCode
 /// &lt;/summary&gt;
 public HttpStatusCode StatusCode { get; set; }
 /// &lt;summary&gt;
 /// The most recent response statusDescription
 /// &lt;/summary&gt;
 public string StatusDescription { get; set; }
 }
</code></pre>

Thus you can do a post and get result via:

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

I am using the <code>WebClient</code> 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 to get the status code if there is a exception

<pre><code>Catch wex As WebException
 If TypeOf wex.Response Is HttpWebResponse Then
 msgbox(DirectCast(wex.Response, HttpWebResponse).StatusCode)
 End If
</code></pre>

However if the form is submitted successfully and no exception is thrown then I won't know the status code(200,301,302,...)

Is there some way to get the status code when there is no exceptions thrown?
