Answer 2

            WebClient wc = new WebClient();
            NameValueCollection vc = new NameValueCollection();
            vc.Add("searchip1","202");
            vc.Add("searchip2","181");
            vc.Add("searchip3","6");
            vc.Add("searchip4","18");            byte[] buff = wc.UploadValues("http://ip.qq.com/cgi-bin/searchip", vc);
            Console.WriteLine(Encoding.Default.GetString(buff));

Answer 3

 客户端
//发送数据
                TcpClient client = new TcpClient(textBox3.Text.Trim()/*ip地址*/, Convert.ToInt32(textBox4.Text.Trim())/*端口*/); //5567
                //文件流
                NetworkStream sendStream = client.GetStream();
                //StreamWriter writer = new StreamWriter(sendStream);
                //发送的内容
                String msg = textBox2.Text;
                //转换为数组
                Byte[] sendBytes = Encoding.Default.GetBytes(msg);
                //发送
                sendStream.Write(sendBytes, 0, sendBytes.Length);
                
              //接收返回数据流
                byte[] bytes = new byte[2048];
                //接收
                sendStream = client.GetStream();                
                int bytesread = sendStream.Read(bytes, 0, bytes.Length);
                //将数据流转换成字符串
                string reciveMsg = Encoding.Default.GetString(bytes, 0, bytesread);            
                sendStream.Close();
                client.Close();
//服务器端
