       string _url = "http://localhost:65022/login/getaa";
       string jsonParam = "{\"a\":\"aa\",\"b\":\"bb\",\"c\":\"cc\"}";
       var request = (HttpWebRequest)WebRequest.Create(_url);
       request.Method = "POST";
       request.ContentType = "application/json;charset=UTF-8";
       var byteData = Encoding.UTF8.GetBytes(jsonParam);
       var length = byteData.Length;
       request.ContentLength = length;
       request.ServicePoint.Expect100Continue = false;
       //ServicePointManager.Expect100Continue = false;
       request.Timeout = 500; //是进行后续同步请求时使用 GetResponse 方法等待响应以及 GetRequestStream 方法等待流所允许的毫秒数
       var writer = request.GetRequestStream();
       writer.Write(byteData, 0, length);
       writer.Close();
  
       //接收响应内容
       var response = (HttpWebResponse)request.GetResponse();
       var responseString = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding("utf-8")).ReadToEnd();
       return responseString.ToString();

  //字符串数据  可以是 “a=aa&b=bb”
  string data="";
  WebRequest myHttpWebRequest = WebRequest.Create(url);
  myHttpWebRequest.Method = "POST";
  UTF8Encoding encoding = new UTF8Encoding();
  byte[] bytepost = encoding.GetBytes(data);
  myHttpWebRequest.ContentType = "application/x-www-form-urlencoded";
  myHttpWebRequest.ContentLength = bytepost.Length;
  Stream newStream = myHttpWebRequest.GetRequestStream();
  newStream.Write(bytepost, 0, bytepost.Length);
  newStream.Close();
  
  //发送成功后接收返回的XML信息
  HttpWebResponse response = (HttpWebResponse)myHttpWebRequest.GetResponse();
  Encoding enc = Encoding.GetEncoding("UTF-8");
  Stream stream = response.GetResponseStream();
  StreamReader streamReader = new StreamReader(stream, enc);
  string retstr = streamReader.ReadToEnd();
  return retstr;
  

接收

   var sr = new StreamReader(Request.InputStream);
   var stream = sr.ReadToEnd();
