关于一些流的处理

WebRequest req = WebRequest.Create(url);
result = req.GetResponse();
Stream ReceiveStream = result.GetResponseStream();
System.Text.Encoding encode = System.Text.Encoding.GetEncoding("gb2312");
StreamReader sr =new StreamReader(ReceiveStream, encode);
Char[] read =new Char[256];
int count = sr.Read(read, 0, 256);

WebResponse HttpWebResponse2 = null;
            HttpWebResponse2 = (WebResponse)request3.GetResponse();
            StreamReader sr2 = null;   //用来读取流  
            Encoding code2 = Encoding.GetEncoding("utf-8");   //定义编码  
            Stream responseStream2 = HttpWebResponse2.GetResponseStream();
            sr2 = new StreamReader(responseStream2, code2);
            string source2 = sr2.ReadToEnd();
            sr2.Close();
            responseStream2.Close();
            source2 = source2.Replace("\n", "").Replace("\t", "").Replace("\r", "").Replace("\"", "'").Replace(" ", "");

string managername = PageHelper.GetRequestStr("managername", Encoding.UTF8);      

 

        public static string GetRequestStr(string key, Encoding encoding)

        {

            string value = string.Empty;

            NameValueCollection uRequest = HttpUtility.ParseQueryString(HttpContext.Current.Request.Url.Query, encoding);

            value = uRequest[key];
