Sokect异步连接发送

客户端

        static void Main(string[] args)
        {
            Console.WriteLine("this is a Client!");

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

            client.Connect(new IPEndPoint(IPAddress.Parse("127.0.0.1"), ));

            while (true)
            {
                string sendmsg = Console.ReadLine();
                client.Send(System.Text.Encoding.Default.GetBytes(sendmsg));
                Console.WriteLine(sendmsg + " is send Ok!");
            }

服务器

 static void Main(string[] args)
        {
            Console.WriteLine("this is a Server!");

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

            server.Bind(new IPEndPoint(IPAddress.Any, ));

            server.Listen();

            server.BeginAccept(Callback, server);

            Console.ReadLine();
        }

        static void Callback(IAsyncResult ar)
        {
            Socket server = (Socket)ar.AsyncState;
            Socket client = server.EndAccept(ar);

            while (true)
            {
                byte[] buffer = new byte[];

                client.Receive(buffer,,buffer.Length,SocketFlags.None);

                Console.WriteLine(System.Text.Encoding.Default.GetString(buffer).Trim());
            }
        }
