//与socket bridge通讯的方法示例
        public string sendAndReceive(string sendMsg)
        {
            TcpClient client = new TcpClient(config.ip, config.port);
            NetworkStream stream = client.GetStream();

            Byte[] data = System.Text.Encoding.UTF8.GetBytes(sendMsg.ToString());
            stream.Write(data, 0, data.Length);
            data = new Byte[50 * 1024];
            String responseData = String.Empty;
            Int32 bytes = stream.Read(data, 0, data.Length);
            responseData = System.Text.Encoding.UTF8.GetString(data, 0, bytes);
            stream.Close();
            client.Close();
            return responseData;
        }

返回的responseData为空

ip和端口设置对吗？ 你用tcp/ip助手（网上有这类的工具）连接下发几个数据试试，看否成功
