Wp7图像没有上传到服务器？

Question

这是我要发布的请求的示例，这是我需要在服务器上发布上传图片的方式：

Request
POST /updateprofile HTTP/1.1
Host: <ip:port>
Content-Type: multipart/mixed, boundary=”myboundary”
User-Agent: <Device User Agent>

--myboundary
Content-Length: 2234
Delegateid=<did>&profileid=0&title=<title>& userid=<uid>&seequestion=<seequestion>&seeanswer=<seeanswer>&fname=<fname>&lname=<lname>&ccountry=<citycountry>&company=<company>&ptitle=<ptitle>&industry=<industry>&looking=<looking>&address=<address>&mobile=<mobile>&phone=<phone>&weburl=<weburl>&keys=k1|k2&values=v1111|v2222&encoding=base64&sendpic=1

--myboundary
Content-Type:image/jpeg
Content-Length: 1234

XXX Binary jpeg image xxx

--myboundary--

我编码但是图片没有在服务器上传，每个东西都已成功发布，我从图片库中取出图片并将其转换为字节数组，但仍然没有结果，我编码如下：< / p>

void _cameraCapture_Completed(object sender, PhotoResult e)
{
capturedImage = e.ChosenPhoto;
BitmapImage bmp = new BitmapImage();
bmp.SetSource(capturedImage);
MemoryStream ms = new MemoryStream();
WriteableBitmap wb = new WriteableBitmap(bmp);
wb.SaveJpeg(ms, 40, 40, 0, 40);
imageBytes = ms.ToArray();
SendPost();
}

   void SendPost()
        {

            if (!System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable())
            {
                MessageBox.Show("No network connection available!");
                return;
            }

            //http://stackoverflow.com/questions/5952094/wp7-windows-phone-7-httpwebrequest-losing-post-data

            System.Uri uri = new Uri("http://www.www.com/updateprofile.do);
            // Create the web request object
            HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(uri);

            webRequest.Method = "POST";
            webRequest.ContentType = "application/x-www-form-urlencoded";

         webRequest.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), webRequest);
        }
  private void GetRequestStreamCallback(IAsyncResult asynchronousResult)
        {

            //postData += ("&profileid=" + "0");
            //postData += ("&title=" + "Mr");
            //postData += ("&userid=" + "iphone@cubixlabs.com");

            //postData += ("&newpasswd=" + "f30aa7a662c728b7407c54ae6bfd27d1");

            byte[] byteArray = Encoding.UTF8.GetBytes(postData);

            // Add the post data to the web request
            postStream.Write(byteArray, 0, byteArray.Length);
            postStream.Close();

            // Start the web request
            webRequest.BeginGetResponse(new AsyncCallback(GetResponseCallback), webRequest);
   }

        void GetResponseCallback(IAsyncResult asynchronousResult)
        {

            HttpWebRequest webRequest = (HttpWebRequest)asynchronousResult.AsyncState;
            HttpWebResponse response;

            // End the get response operation
            response = (HttpWebResponse)webRequest.EndGetResponse(asynchronousResult);
            Stream streamResponse = response.GetResponseStream();
            StreamReader streamReader = new StreamReader(streamResponse);
            var Response = streamReader.ReadToEnd();
            //MessageBox.Show(Response.ToString());


        }
