本文主要是介绍客户端发送信息给服务器以及服务器接收客户端发来的信息(socket),对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

服务器端:

            Socket socketWatch = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            //创建IP地址和端口号对象
            IPAddress ip = IPAddress.Any;//这句Any是获取自己当前本机的IP,
            //IPAddress ip=IPAdress.Parse(txtIP.Text); 这句是获取textbox里面输入的地址
            IPEndPoint point = new IPEndPoint(ip, Convert.ToInt32(txtPort.Text));//这里是获取文本框里输入的端口号,创建了一个端口对象,需要传入ip跟端口号
            //让负责监听的Socket绑定IP地址跟端口号
            socketWatch.Bind(point);
