网络-如何制作服务器? [英] Networking - How make a server?

问题描述

您好，我正在学习编程，因此我需要解决新问题.我想将服务器写入我的应用程序.我的问题在哪里?因此，当我的服务器从任何客户端接收消息时，它都应将重播发送给所有客户端.我不知道我的客户应该如何等待此重播，服务器中的所有三元组如何将相同的重播发送给客户端.

我的英语很抱歉:)
为了更好地了解我的问题，我制作了动画:

I don''t know how my clients should waiting for this replay and how all threeds in server send same replay to clients.

Sory for my English :)
To better see my problem I do animation:

推荐答案

每个客户端使用单独的线程是一种非常糟糕的主意.我不会带你去的为什么?

请查看我过去对相关问题的回答，它可以给您一个正确的主意:
来自同一端口号的多个客户端 [

Using a separate thread per client is a very bad idea. I will lead you nowhere. Why?

Please see my past answer to a related question, it can give you a right idea:
Multple clients from same port Number[^].

—SA

我做了类似的事情

I make samething like this

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

namespace server
{
    class server
    {
        List<tcpclient> clientList;
        TcpListener listener;

        public server(int port)
        {
            clientList = new List<tcpclient>();
            listener = new TcpListener(System.Net.IPAddress.Any, port);
            listener.Start();

        }

        public void listengForClient()
        {
            Thread newClient = new Thread(listeningForNewClient);
            newClient.Start();
        }

        private void listeningForNewClient()
        {
            while (true)
            {
                TcpClient client = default(TcpClient);
                client = listener.AcceptTcpClient();

                lock (clientList)
                {
                    clientList.Add(client);
                    Console.WriteLine(" >> Adding new client... Client count: " + clientList.Count);
                }
            }
        }

        public void receiveDateFromClients()
        {
            Thread receiver = new Thread(receiveDate);
            reciver.Start();
        }

        private void receiveDate()
        {
            while (true)
            {
                lock(clientList)
                for (int i = 0; i < clientList.Count; i++)
                {
                    if (clientList[i].Connected)
                    {
                        if (clientList[i].Available > 0)
                        {
                            // get message form i-client
                            Console.WriteLine(" >> >> >> Message from client: " + i);
                            
                        }
                    }
                    else
                    {
                        // client disconnected so it is removing
                        Console.WriteLine(" >> >> Removing client: " + i);
                        clientList.RemoveAt(i);
                        i--; if (i < 0) i = 0;
                    }
                }
            }
        }
    }
}
</tcpclient></tcpclient>

我知道接收日期不好，因为它使用了95％的CPU，但是我不知道如何做得更好...

I know receiving date is bad, becaouse it uses 95% CPU, but I don''t know how do it better...
