来自IP cam C#的流

我有以下代码无效.我的camUrl链接可以正常工作,如果我加载到Firefox并从我的摄像头流,但在运行时我的图片框中没有显示任何内容.有什么想法吗？

public Thread _camThread;
        private String camUrl = "http://my-domain-ip:2080/videostream.cgi?user=admin&pwd=password";
        public httpWebrequest webReq;
        public WebResponse webRes;
        public Stream sr;

        private void btnStart_Click(object sender,EventArgs E)
        {
            if (_camThread == null) _camThread = new Thread(new ThreadStart(RunCam));
            _camThread.Start();
        }

        private void RunCam()
        {
            try
            {
                webReq = (httpWebrequest)Webrequest.Create(camUrl);
                webReq.AllowWriteStreamBuffering = true;
                webReq.Timeout = 20000;
                using (webRes = webReq.GetResponse())
                {
                    while ((sr = webRes.GetResponseStream()) != null)
                    {
                        image.Image = Image.FromStream(sr);
                    }
                }
            }
            catch (Exception eX)
            {
                messageBox.Show(ex.messagE);
            }
        }

        private void btnStop_Click(object sender,EventArgs E)
        {
            if (_camThread.IsAlivE)
            {
                _camThread.abort();
                _camThread = null;
            }
        }

using (webRes = webReq.GetResponse())
{
    using (sr = webRes.GetResponseStream())
    {
        // conTinuously read images from the response stream until error
        while (true)
        {
            try
            {
                // note: the line below probably won't work,you may need to parse
                // the next image from the multi-part response stream manually
                image.Image = Image.FromStream(sr);


                // if the above doesn't work,then do something like this:
                // var imageBytes = ParseNextImage(sr);
                // var memoryStream = new MemoryStream(imageBytes);
                // image.Image = Image.FromStream(memoryStream);
            }
            catch(Exception E)
            {
                Console.WriteLine("AborTing read from response stream due to error {0}",E);
                break;
            }
        }
    }
}
