面向对象(二十五)-Socket|面向对象(二十五)-Socket, UDP客户端,服务器端

1.服务端代码

static void Main(string[] args) { Socket server = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); server.Bind(new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8090)); EndPoint clientPoint= new IPEndPoint(IPAddress.Any, 0); // 声明一个空的端口对象,当接受到数据的时候,会将数据发送方的地址赋值到该对象中 byte[] reciveData = https://www.it610.com/article/new byte[1024]; int dataLength = server.ReceiveFrom(reciveData, ref clientPoint); //接收到连接,会将连接方的地址写入clientPoint string reciveMessage = Encoding.UTF8.GetString(reciveData, 0, dataLength); Console.WriteLine(reciveMessage); server.Close(); Console.ReadKey(); }

2.客户端代码
static void Main(string[] args) {Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); string userMessage = Console.ReadLine(); byte[] data = https://www.it610.com/article/Encoding.UTF8.GetBytes(userMessage); EndPoint serverPoint = new IPEndPoint(IPAddress.Parse("192.168.1.255"), 8090); clientSocket.SendTo(data, serverPoint); Console.ReadKey(); }
