这篇文章主要介绍了c# socket编程实现udp客户端，大家参考使用吧
代码如下:Console.WriteLine("This is a Client, host name is {0}", Dns.GetHostName());//设置服务端终结点IPEndPoint ipe = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8001);//创建与服务端连接的套接字，指定网络类型，数据连接类型和网络协议Socket ConnSocket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);string welcome = "Client Message:Hello!!!";byte[] data = new byte[1024];data = Encoding.ASCII.GetBytes(welcome);//给服务端发送测试消息ConnSocket.SendTo(data, data.Length, SocketFlags.None, ipe);IPEndPoint server = new IPEndPoint(IPAddress.Any, 0);//服务端终结点EndPoint Remote = (EndPoint)server;data = new byte[1024];//对于不存在的IP地址，加入此行代码后，可以在指定时间内解除阻塞模式限制//server.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReceiveTimeout, 100);int recv = ConnSocket.ReceiveFrom(data, ref Remote);//打印从服务端发回的信息Console.WriteLine("Message received from {0}: ", Remote.ToString());Console.WriteLine(Encoding.ASCII.GetString(data, 0, recv));while (true) //可以实时给服务端发送消息{ string input = Console.ReadLine(); if (input == "exit") //中断连接 { ConnSocket.SendTo(Encoding.ASCII.GetBytes(input), Remote); data = new byte[1024]; recv = ConnSocket.ReceiveFrom(data, ref Remote); Console.WriteLine(Encoding.ASCII.GetString(data, 0, recv)); break; } else { ConnSocket.SendTo(Encoding.ASCII.GetBytes("Client Message:" + input), Remote); data = new byte[1024]; recv = ConnSocket.ReceiveFrom(data, ref Remote); Console.WriteLine(Encoding.ASCII.GetString(data, 0, recv)); }}Console.WriteLine("Stopping Client.");ConnSocket.Close();
