Socket編輯基礎tcp通訊

 

SocketServer 端應用程式

static void Main(string[] args)
        {

            IPAddress address = IPAddress.Parse("127.0.0.1");
            IPEndPoint point = new IPEndPoint(address, 3000);
          
            Socket server = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            server.Bind(point);
            server.Listen(3);
            Socket client;
            byte[] buffer = new byte[1024];
            int i = 0;
            string data;
            Console.WriteLine("等待串連...");
            if ((client = server.Accept()) != null)//進程等待
            {
                Console.WriteLine("使用者已串連...");
                while (true)
                {
                    if ((i = client.Receive(buffer)) != 0)//進程等待
                    {
                        data = System.Text.Encoding.UTF8.GetString(buffer, 0, i);
                        Console.WriteLine("收到的資訊為{0}", data);
                        Console.Write("請輸入回複資訊:");
                        string input = Console.ReadLine();
                        client.Send(System.Text.Encoding.UTF8.GetBytes(input));
                    }
                }
            }

            Console.ReadLine();
        }

socketClient用戶端程式

  static void Main(string[] args)
        {
            IPAddress address = IPAddress.Parse("127.0.0.1");
          
            IPEndPoint point = new IPEndPoint(address, 3000);
            Socket Client = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            Client.Connect(point);//進程等待
            Console.WriteLine("已串連到伺服器...");
            byte[] buffer = new byte[1024];
            string data = null;
            while (true)
            {
                Console.Write("請輸入要發送的資訊:");
                string input;
                input = Console.ReadLine();
                if (input == "exit")
                    break;
                Client.Send(System.Text.Encoding.UTF8.GetBytes(input));
              
                int i = 0;
                i = Client.Receive(buffer);//進程等待
                if (i > 0)
                {
                    Console.Write("伺服器回複資訊:");
                    data = System.Text.Encoding.UTF8.GetString(buffer, 0, i);
                    Console.WriteLine(data);
                }
            }
            Console.WriteLine("中斷連線...");
            Client.Shutdown(SocketShutdown.Both);
            Client.Close();
        }
