post 数据过去

private string Post(string strURL, string paramString)
        {
            string pagehtml = string.Empty;
            try
            {
                Encoding myEncoding = Encoding.GetEncoding("UTF-8");
                Uri myUri = new Uri(strURL);
                byte[] paramBytes = myEncoding.GetBytes(paramString);
                HttpWebRequest myWebRequest = (HttpWebRequest)WebRequest.Create(myUri);
                myWebRequest.ContentType = "application/x-www-form-urlencoded";
                myWebRequest.AllowAutoRedirect = true;
                myWebRequest.Method = "POST";
                myWebRequest.Timeout = 60000;
                myWebRequest.ContentLength = paramBytes.Length;

                //Send request
                Stream requestStream = myWebRequest.GetRequestStream();
                requestStream.Write(paramBytes, 0, paramBytes.Length);
                requestStream.Close();

               //or we can user below

               

//或者
  using (Stream postStream =myWebRequest.GetRequestStream()) {
                    using (StreamWriter writer = new StreamWriter(postStream)) {
                        writer.Write(requestPayload);
                    }
                } 

                //Get response
                HttpWebResponse myWebResponse = (HttpWebResponse)myWebRequest.GetResponse();
                StreamReader myStreamReader = new StreamReader(myWebResponse.GetResponseStream(), myEncoding);
                pagehtml = myStreamReader.ReadToEnd();
                myStreamReader.Close();
            }
            catch (Exception ex)
            {
                return string.Empty;
            }            
            return pagehtml;
        }      

响应post过来的数据

如果是XML

XML = Request["xml"].ToString();

为response 信息添加头

Response.AppendHeader(
                "X-XRDS-Location",
                new Uri(Request.Url, Response.ApplyAppPathModifier("~/xrds3")).AbsoluteUri);
