救命！！！如何在TCP IP侦听器中发送ACK数据包c＃ [英] HELP!!! How do I send an ACK packet in TCP IP Listener c#

问题描述

我想创建TCP IP侦听器 和医疗沟通 设备。 

请告知我们如何从服务器向客户端发送ACK数据包（医疗设备） 

 

解决方案

< pre class ="prettyprint">使用System;
使用System.Collections.Generic;
使用System.Linq;
使用System.Text;
使用System.Net;
使用System.Net.Sockets;

名称空间TCPServer
{
class程序
{
static void Main（string [] args）
{
int recv ;
byte [] data = new byte [1024];

IPEndPoint ipep = new IPEndPoint（IPAddress.Any，9050）;

Socket newsock = new Socket（AddressFamily.InterNetwork，SocketType.Stream，ProtocolType.Tcp）;

newsock.Bind（ipep）;
newsock.Listen（10）;

Console.WriteLine（" Waiting for client ..."）;

Socket client = newsock.Accept（）;

IPEndPoint clienttep =（IPEndPoint）client.RemoteEndPoint;

Console.WriteLine（"与端口{1}的{0}连接"，clienttep.Address，clienttep.Port）;

string welcome =" Welcome to my Server" ;;

data = Encoding.ASCII.GetBytes（welcome）;

client.Send（data，data.Lengt，SocketFlags.None）;

while（true）
{
data = new byte [1024];

recv = client.Receive（data）;

if（recv == 0）break;

Console.WriteLine（Encoding.ASCII.GetString（data，0，recv））;

client.Send（data，recv，SocketFlags.None）;
}

Console.WriteLine（" Disachedcted from {0}"，clienttep.Address）;

client.Close（）;
newsock.Close（）;
}
}
}

I want to created TCP IP Listener  and communicate with medical  device . 

Kindly advise us how to send ACK Packet from Server to Client (Medical device)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.Net.Sockets;

namespace TCPServer
{
    class Program
    {
        static void Main(string[] args)
        {
            int recv;
            byte[] data = new byte[1024];

            IPEndPoint ipep = new IPEndPoint(IPAddress.Any, 9050);

            Socket newsock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

            newsock.Bind(ipep);
            newsock.Listen(10);

            Console.WriteLine("Waiting for client...");

            Socket client = newsock.Accept();

            IPEndPoint clienttep = (IPEndPoint)client.RemoteEndPoint;

            Console.WriteLine("Connected with {0} at port {1}", clienttep.Address, clienttep.Port);

            string welcome = "Welcome to my Server";

            data = Encoding.ASCII.GetBytes(welcome);

            client.Send(data, data.Lengt, SocketFlags.None);

            while (true)
            {
                data = new byte[1024];

                recv = client.Receive(data);

                if (recv == 0) break;

                Console.WriteLine(Encoding.ASCII.GetString(data, 0, recv));

                client.Send(data,recv, SocketFlags.None);
            }

            Console.WriteLine("Disconnected from {0}", clienttep.Address);

            client.Close();
            newsock.Close();
        }
    }
}
