C# 实现WebSocket通信

　　本实例可通过web网页端进行测试，下面直接上代码。

　　首先要在NuGet导入“Fleck”包，需 .NET Framework 4.5及以上。

using System; using System.Collections.Generic; using System.Linq; using System.Threading; namespace Fleck.Samples.ConsoleApp { class Server { static void Main() { FleckLog.Level = LogLevel.Debug; var allSockets = new List<IWebSocketConnection>(); var server = new WebSocketServer("ws://10.10.10.99:50000"); 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)); }; }); var input = Console.ReadLine(); while (input != "exit") { foreach (var socket in allSockets.ToList()) { socket.Send(input); } input = Console.ReadLine(); } } } }
