C# socket编程 使用fleck轻松实现对话 https://github.com/statianzo/Fleck
class Program { static void Main(string[] args) { FleckLog.Level = LogLevel.Debug; var allSockets = new List<IWebSocketConnection>(); var server = new WebSocketServer("ws://0.0.0.0:7181"); server.Start(socket => { socket.OnOpen = () => { Console.WriteLine("Open!"); allSockets.Add(socket); }; socket.OnClose = () => { Console.WriteLine("Close!"); allSockets.Remove(socket); }; socket.OnMessage = message => { Console.WriteLine(message); allSockets.ToList().ForEach(s => s.Send("Echo: " + message)); }; socket.OnBinary = file => { string path = ("D:/test.txt"); //创建一个文件流 FileStream fs = new FileStream(path, FileMode.Create); //将byte数组写入文件中 fs.Write(file, 0, file.Length); //所有流类型都要关闭流，否则会出现内存泄露问题 fs.Close(); }; }); var input = Console.ReadLine(); while (input != "exit") { foreach (var socket in allSockets.ToList()) { socket.Send(input); } input = Console.ReadLine(); } } } |
