为了测试多台设备数据并发的问题，我需要选择同步或者异步方式的Socket服务端，于是写了两个来测试.我发现差不多的代码 取得的结果却不一样，你们看看，我代码哪里错了，数据都可以正常接收，只不过我加了一个合包处理.异步服务端取得的结果是错的。同步+多线程是正常的。折腾死了，希望大家帮帮忙。我需要做一个可以供200-500台设备数 据并发的服务端。
异步:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Net.Sockets; using System.Net; using System.Threading; using System.Text.RegularExpressions; namespace SocketServer { class Program { static byte[] buffer = new byte[1024]; static IDictionary<Socket, byte[]> socketClientSesson = new Dictionary<Socket, byte[]>(); static void Main(string[] args) { var socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); socket.Bind(new IPEndPoint(IPAddress.Parse("192.168.0.103"), 4001)); socket.Listen(500); while (true) { IAsyncResult result = socket.BeginAccept(new AsyncCallback(ClientAccepted), socket); result.AsyncWaitHandle.WaitOne(); }; } public static void ClientAccepted(IAsyncResult ar) { if (!ar.IsCompleted) { return; } var socket = ar.AsyncState as Socket; var client = socket.EndAccept(ar); socketClientSesson.Add(client, buffer); if (client.Connected) { try { Console.WriteLine(Encoding.Unicode.GetBytes("Message from server at " + DateTime.Now.ToString())); } catch (SocketException ex) { Console.WriteLine(ex.Message); } client.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(ReceiveMessage), client); socket.BeginAccept(new AsyncCallback(ClientAccepted), socket); } else { Console.WriteLine("Client is disconnected, the timer is stop."); } } public static void ReceiveMessage(IAsyncResult ar) { try { var socket = ar.AsyncState as Socket; if (socket == null || !socketClientSesson.ContainsKey(socket)) { return; } var length = socket.EndReceive(ar); byte[] buf = socketClientSesson[socket]; Array.Copy(buffer, buf, buf.Length); ByteQueue queue = new ByteQueue(); queue.Enqueue(buf); while (queue.Find()) { byte[] readBuffer = queue.Dequeue(); var message = BitConverter.ToString(readBuffer); if (message.StartsWith("FF-FF-FF-FF-CA-CB-CC-CD") && message.EndsWith("EA-EB-EC-ED")) { string repStr = message.Replace("-", " "); Regex regex = new Regex("07 81 08.{24}"); MatchCollection matches = regex.Matches(repStr, 0); if (matches.Count > 0) { //显示消息 Console.WriteLine(message); } } } socket.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(ReceiveMessage), socket); } catch (Exception ex) { Console.WriteLine(ex.Message); } } } }
