public delegate void HttpHandle(object sender, HttpResultArgs args);
    public class HttpGet
    {
        public event HttpHandle HttpGetCompleted;
        public string url;

        public void GetRequestAsync(string url)
        {
            string resultStrings;
            HttpWebRequest req = HttpWebRequest.CreateHttp(url);
            req.BeginGetResponse((ar) =>
            {
                HttpWebRequest req2 = (HttpWebRequest)ar.AsyncState;
                HttpWebResponse response;

                // End the get response operation 
                response = (HttpWebResponse)req2.EndGetResponse(ar);
                Stream streamResponse = response.GetResponseStream();
                StreamReader streamReader = new StreamReader(streamResponse);
                resultStrings = streamReader.ReadToEnd();
                if (HttpGetCompleted != null)
                {
                    HttpResultArgs args = new HttpResultArgs();
                    args.resultString = resultStrings;
                    HttpGetCompleted(this, args);
                }
            }

                HttpWebResponse response;

                // End the get response operation 
                response = (HttpWebResponse)req2.EndGetResponse(ar);
                Stream streamResponse = response.GetResponseStream();
                StreamReader streamReader = new StreamReader(streamResponse);
                resultStrings = streamReader.ReadToEnd();
                if (HttpGetCompleted != null)
                {
                    HttpResultArgs args = new HttpResultArgs();
                    args.resultString = resultStrings;
                    HttpGetCompleted(this, args);
                }
            }
            , req);
        }
