求翻译以下c#代码，谢谢！
string hdcontrolurl = "http://tc.hd.;
         request = WebRequest.Create(hdcontrolurl) as HttpWebRequest;
         request.CookieContainer = cookieContainer;
         request.Method = "GET";
         request.Host = "tc.hd.;
         request.UserAgent = "Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.62 Safari/537.36";
         response = (HttpWebResponse)request.GetResponse();
         Stream instream = response.GetResponseStream();
         sr = new StreamReader(instream, encoding);
         content = sr.ReadToEnd();
