Question

我正在研究用C＃.So Guide编写的多线程服务器和客户端我如何在服务器中为多客户端创建多线程。

这是我的服务器代码

class Program
            {
                static byte[] Buffer
                {

                    get; 
                    set; 
                }
                static void Main(string[] args)
                {
                    Program obj = new Program();
                    Console.WriteLine("Server");
                    obj.server_reciver();


                }
              static Socket sck;

                public void server_reciver()
                {
                    try
                    {
                        sck = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
                        IPEndPoint localEndPoint;
                        localEndPoint = new IPEndPoint(IPAddress.Parse("127.0.0.2"), 1);
                        sck.Bind(localEndPoint);

                        sck.Listen(100);
                        while (true)
                        {
                            Socket accepted = sck.Accept();
                            // Buffer = new byte[accepted.ReceiveBufferSize];
                            Buffer = new byte[accepted.SendBufferSize];
                            int bytesRead = accepted.Receive(Buffer);

                            byte[] formatted = new byte[bytesRead];

                            //for (int i = 0; i < bytesRead; i++)
                            for (int i = 0; i < bytesRead; i++)
                            {
                                formatted[i] = Buffer[i];
                                //Console.WriteLine(Buffer[i] + "\r\n");
                            }
                            //string strData = Encoding.ASCII.GetString(Buffer);
                            string strData = Encoding.ASCII.GetString(formatted);
                            Console.Write("From Client=>" + strData + "\n");
                            Console.WriteLine("Enter the text:");
                            string data = Console.ReadLine();
                            byte[] reply = Encoding.ASCII.GetBytes(data);
                            accepted.Send(reply);
                            //accepted.Close();
                            accepted.Close();
                        }


                        sck.Close();
                        Console.Read();

                    }
                    catch (Exception ex)
                        {

                        }
                }

            }

这是我的客户端，我在这里制作了多个客户端

class Program
                {
                    static byte[] Buffer
                    {

                        get;
                        set;
                    }

                    static Socket sck;
                    static void Main(string[] args)
                    {

                        Program obj = new Program();
                        obj.client_send();
                    }

                    public void client_send()
                    {
                        while (true)
                        {
                            sck = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);


                            IPEndPoint localEndPoint;
                            localEndPoint = new IPEndPoint(IPAddress.Parse("182.188.247.244"), 1);
                            //localEndPoint = new IPEndPoint(IPAddress.Parse("192.168.1.45"), 1);
                            try
                            {
                                sck.Connect(localEndPoint);

                            }
                            catch
                            {
                                Console.Write("Unable to connect to remote end point!\r\n");
                                //Main(args);
                            }

                            try
                            {
                                Console.Write("Enter Text: ");
                                string text = Console.ReadLine();
                                byte[] data = Encoding.ASCII.GetBytes(text);
                                sck.Send(data);

                                Buffer = new byte[sck.SendBufferSize];
                                int bytesRead = sck.Receive(Buffer);

                                byte[] formatted = new byte[bytesRead];


                                for (int i = 0; i < bytesRead; i++)
                                {
                                    formatted[i] = Buffer[i];
                                    //Console.WriteLine(Buffer[i] + "\r\n");
                                }
                                string strData = Encoding.ASCII.GetString(formatted);
                                Console.Write("From Server=>" + strData + "\n");

                                sck.Close();
                            }
                            catch(Exception )
                            {

                            }
                        }

                        Console.ReadLine();
                    }
                }

通常，您会在主线程上保留Socket accepted = sck.Accept();，但是一旦收到请求，您就会将其传递给另一个线程进行维护。这允许主线程列出到另一个传入请求。您可以使用ThreadPool.QueueUserWorkItem将工作移至后台线程。请注意，由于从控制台读取响应，因此将其设置为多线程会给您带来问题。每个工作线程如何知道它获得了正确的数据？但我认为你会用真正的服务器逻辑取代它。

在某些时候，您可能会发现这不会扩展。您正在使用阻止IO调用（Send和Receive），因此您的线程将花费大量时间等待。非阻塞IO是理想的，但编写起来更复杂。
