C#客户端通过IP端口号连接服务端

返回用来收发数据的套接字

       private Socket getSocket(string ip, int p)
        {
           Socket socketclient = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            //获取文本框中的IP地址  
            IPAddress address = IPAddress.Parse(ip);

            //将获取的IP地址和端口号绑定在网络节点上  
            IPEndPoint point = new IPEndPoint(address, p);
           
            //客户端套接字连接到网络节点上，用的是Connect  
            socketclient.Connect(point);
            return socketclient;

        }
