C#中Post和Get提交

1、Post提交

 private string PostWebRequest(string Url, string paramData, string dataEncode)

        {

            string ret = string.Empty;

            try

            {

                Encoding myEncoding = Encoding.GetEncoding(dataEncode);

                byte[] byteArray = myEncoding.GetBytes(paramData); //转化

                HttpWebRequest webReq = (HttpWebRequest)WebRequest.Create(Url);

                webReq.Method = “POST”;

                webReq.ContentType = "application/x-www-form-urlencoded";

                webReq.ContentLength = byteArray.Length;

                Stream newStream = webReq.GetRequestStream();

                newStream.Write(byteArray, , byteArray.Length);//写入参数

                newStream.Close();

                HttpWebResponse response = (HttpWebResponse)webReq.GetResponse();

                StreamReader sr = new StreamReader(response.GetResponseStream(), myEncoding);

                ret = sr.ReadToEnd();

                sr.Close();

                response.Close();

            }

            catch (Exception ex)

            {

                WriteFileLog(ex.ToString());

                MessageBox.Show(ex.Message);

            }

            return ret;

        }

2、Get提交

   private string GetWebRequest(string Url, string paramData, string dataEncode)

        {

            string requestString = "";

            try

            {

                string reallyUrl = Url;

                Encoding myEncoding = Encoding.GetEncoding(dataEncode);

                // CookieContainer cookieContainer = new CookieContainer();

                HttpWebRequest request = WebRequest.Create(reallyUrl) as HttpWebRequest;

                //  ServicePointManager.CheckCertificateRevocationList = false;

                request.Method = “GET”;

                //   request.KeepAlive = false;

                //   request.AllowAutoRedirect = true;

                request.ContentType = "application/x-www-form-urlencoded";

                HttpWebResponse response = (HttpWebResponse)request.GetResponse();

                StreamReader responseStream = new StreamReader(response.GetResponseStream(), myEncoding);

                requestString = responseStream.ReadToEnd();

                response.Close();

                responseStream.Close();

            }

            catch (Exception ex)

            {

                WriteFileLog(ex.ToString());

                MessageBox.Show(ex.Message);

            }
