TcpClient 读写流

           TcpClient tcp = new TcpClient();
                tcp.Connect(IPAddress.Parse("192.168.1.161"), 8885);//根据服务器的IP地址和侦听的端口连接
            if (tcp.Connected)
            {

                    //获取网络流
                    NetworkStream networkStream = tcp.GetStream();
                    //将网络流作为二进制读写对象
                    br = new BinaryReader(networkStream);
                    bw = new BinaryWriter(networkStream);

                    bw.Write(str);//发送字符串命令
                    string result = br.ReadString();
                    if (result == "OK")
                    {
