以下是一段通过ip138站点的请求，以查询手机归属地的代码：
           string postData = "mobile=13824162584&action=mobile";
            byte[] bs = Encoding.ASCII.GetBytes(postData);
            WebRequest req = WebRequest.Create("http://www.ip138.com:8080/search.asp");
            req.Method = "POST";
            req.ContentType = "application/x-www-form-urlencoded";
            req.ContentLength = bs.Length;
           
            using (Stream reqStream = req.GetRequestStream())
            {
                reqStream.Write(bs, 0, bs.Length);
            }
            
            using (WebResponse wr = req.GetResponse())
            {
                //在这里对接收到的页面内容进行处理
                Encoding encode = System.Text.Encoding.GetEncoding("gb2312");
                string tempStr = "";
                string sb = "";
                Stream receviceStream = wr.GetResponseStream();
                while(true)
                {
                    byte[] read = new byte[1024];
                    int iBytes = receviceStream.Read(read, 0, read.Length);
                    if (0 == iBytes)
                    {
                        break;
                    }
                    if (iBytes < read.Length)
                    {
                        byte[] buf = new byte[iBytes];
                        for (int i = 0; i < iBytes; i++)
                        {
                            buf[i] = read[i];
                        }
                        tempStr = encode.GetString(buf);
                        sb += tempStr;
                    }
                    else
                    {
                        tempStr = encode.GetString(read);
                        sb += tempStr;
                    }
                }
            }
