Answer 1

HttpWebRequest限制太多太烦...
个人推荐用WinHttp.

Answer 2

httpwebrequest 使用简单，但有各种各样限制写不出功能变态的东西来

Answer 3

直接用 socket 自由一些,
调用那个天气预报 web service 的例子:      string requestHeader = null;
      string requestBody = null;
      requestBody = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\r\n"
                  + "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\r\n"
                  + "  <soap:Body>\r\n"
                  + "    <getWeatherbyCityName xmlns=\"http://WebXml.com.cn/\">\r\n"
                  + "      <theCityName>" + areaCode + "</theCityName>\r\n"
                  + "    </getWeatherbyCityName>\r\n"
                  + "  </soap:Body>\r\n"
                  + "</soap:Envelope>";
      requestHeader = "POST /WebServices/WeatherWebService.asmx HTTP/1.1\r\n"
                  + "Host: www.webxml.com.cn\r\n"
                  + "Content-Type: text/xml; charset=utf-8\r\n"
                  + "Content-Length: " + requestBody.Length + "\r\n"
                  + "SOAPAction: \"http://WebXml.com.cn/getWeatherbyCityName\"\r\n"
                  + "Connection: Close\r\n\r\n";
      string request = requestHeader + requestBody;
      _hevt_socket_closed.Reset();
      _rcv_buff = "";
      _proxy.Send(_remoteHost, _remotePort, request);

Answer 4

HttpWebRequest test .....
标头加入到Headers集合中
test.Headers.Add(name,value);
..............有些标头名称直接为HttpWebRequest属性.直接赋值即可!

Answer 5

webrequest.headers.add
webrequset.headers["名称"]="值"
