C# windows to C# phone windows

问题

This is more a task to ask than help but... after 1 day of tries I can't get it work. This is my code

private string _InetReadEx(string sUrl)
        {

            HttpWebRequest webReq = (HttpWebRequest)HttpWebRequest.Create(sUrl);
            try
            {
                webReq.CookieContainer = new CookieContainer();
                webReq.Method = "GET";
                using (WebResponse response = webReq.GetResponse())
                {
                    using (Stream stream = response.GetResponseStream())
                    {
                        StreamReader reader = new StreamReader(stream);
                        aRet = reader.ReadToEnd();
                        return aRet;
                    }
                }
            }
            catch (Exception ex)
            {
                return ex.Message;
            }

        }

What this code does is simple. It returns the source of a server. So here is my silly question; how can I do something similar on C# windows phone(windows phone 8.1/8)?

Thank you in advance, Maria
