C# socket 实现客户端连续发送数据

服务器端：

namespace SocketTest
{
     
    class Program
    {
        public static void SendMessage()
        {
            Socket socket = serverSocket.Accept();
            Console.WriteLine("Connected a client:{0}",socket.RemoteEndPoint);
            socket.Send(Encoding.ASCII.GetBytes("welcome to server"));
            //Thread thread = new Thread(ReceiveMessage);
           // thread.Start();
        }

        public static void ReceiveMessage(object obj)
        {
            Socket socket = (Socket)obj;
            byte[] data = new byte[1024];
            int len = socket.Receive(data);
            string dataString = Encoding.ASCII.GetString(data, 0, len);
            Console.WriteLine("Receive Data:{0} from {1}", dataString,socket.RemoteEndPoint);
            //Thread thread = new Thread(SendMessage);
            //thread.Start(socket);
        }


        static Socket serverSocket;
        static void Main(string[] args)
        {
            //定义接收数据长度变量
            int recv;
            //定义接收数据的缓存
            byte[] data = new byte[1024];
            //定义侦听端口
            IPEndPoint ipEnd = new IPEndPoint(IPAddress.Any, 5566);
            //定义套接字类型
            serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            //连接
            serverSocket.Bind(ipEnd);
            //开始侦听
            serverSocket.Listen(10);
            //控制台输出侦听状态
            Console.Write("Waiting for a client");
            //Socket client;
            while (true)
            {
                    //一旦接受连接，创建一个客户端
                    Socket client = serverSocket.Accept();
                    //获取客户端的IP和端口
                    IPEndPoint ipEndClient = (IPEndPoint)client.RemoteEndPoint;
                    //输出客户端的IP和端口
                    Console.WriteLine("Connect with {0} at port {1}", ipEndClient.Address, ipEndClient.Port);
                    //定义待发送字符
                    string welcome = "Welcome to my server";
                    //数据类型转换
                    data = Encoding.ASCII.GetBytes(welcome);
                    while (true)
                    {
                        
                        try
                        {
                            //发送
                            client.Send(data, data.Length, SocketFlags.None);
                            //接收数据可以用线程也可以不用
                            //ReceiveMessage(client);
                            Thread thread = new Thread(ReceiveMessage);
                            thread.Start(client);
                            ////对data清零
                            //data = new byte[1024];
                            ////获取收到的数据的长度
                            //recv = client.Receive(data);
                            ////如果收到的数据长度为0，则退出
                            //if (recv == 0)
                            //    break;
                            ////输出接收到的数据
                            //Console.WriteLine(Encoding.ASCII.GetString(data, 0, recv));
                            //将接收到的数据再发送出去
                            // client.Send(data, recv, SocketFlags.None);
                        }
                        catch (Exception)
                        {
                            client.Close();
                            serverSocket.Close();

                        }
                    }
                    client.Close();
            }
            //Console.WriteLine("Disconnect form{0}", ipEndClient.Address);
           
            serverSocket.Close();
        

        }
    }

客户端：

                }

                socket.Send(data, data.Length, SocketFlags.None);

                //if (input == "exit")
                //{
                //    break;
                //}
                ////对data清零
