<p class="maodian"></p><h2>二、核心模块实现</h2>
<p class="maodian"></p><h3>1. 通信网关（TCP服务端）</h3>
<div class="jb51code"><pre class="brush:csharp;">public class TcpGateway
{
    private TcpListener _listener;
    private ConcurrentDictionary&lt;string, Socket&gt; _clients = new();

    public async Task StartAsync(string ip, int port)
    {
      _listener = new TcpListener(IPAddress.Parse(ip), port);
      await _listener.StartAsync();
      
      while (true)
      {
            var client = await _listener.AcceptTcpClientAsync();
            _ = HandleClientAsync(client);
      }
    }

    private async Task HandleClientAsync(TcpClient client)
    {
      using (client)
      {
            var stream = client.GetStream();
            var buffer = new byte;
            
            while (client.Connected)
            {
                int bytesRead = await stream.ReadAsync(buffer, 0, buffer.Length);
                if (bytesRead == 0) break;

                await MessageDispatcher.Dispatch(msg);
            }
      }
    }
}
</pre></div>
<p class="maodian"></p><h3>2. 消息协议设计</h3>
<div class="jb51code"><pre class="brush:csharp;">public class MessageProtocol
{
    public ushort Magic { get; set; } = 0xA55A;
    public byte Version { get; set; }
    public MessageType Type { get; set; }
    public int BodyLength { get; set; }
    public byte[] Body { get; set; }
}

public enum MessageType
{
    Login = 1,
    Text = 2,
    File = 3,
    Heartbeat = 4
}
</pre></div>
<p class="maodian"></p><h3>3. 消息处理中心</h3>
<div class="jb51code"><pre class="brush:csharp;">public static class MessageDispatcher
{
    public static async Task Dispatch(MessageProtocol msg)
    {
      switch (msg.Type)
      {
            case MessageType.Login:

                HeartbeatManager.KeepAlive(msg.SessionId);
                break;
      }
    }
}
</pre></div>
<p class="maodian"></p><h2>三、关键技术实现</h2>
<p class="maodian"></p><h3>1. 高并发处理</h3>
<div class="jb51code"><pre class="brush:csharp;">// 使用线程池优化资源
ThreadPool.SetMinThreads(50, 50);

// 异步处理消息
public async Task ProcessMessageAsync(Socket socket)
{
    var buffer = new byte;
    while (true)
    {
      int bytesRead = await socket.ReceiveAsync(
            new ArraySegment&lt;byte&gt;(buffer),
            SocketFlags.None);
      
      if (bytesRead == 0) break;
      
      _ = Task.Run(() =&gt; HandleData(buffer, bytesRead));
    }
}
</pre></div>
<p class="maodian"></p><h3>2. 消息持久化</h3>
<div class="jb51code"><pre class="brush:csharp;">public class ChatRepository
{
    private readonly DbContext _context;

    public async Task SaveMessage(ChatMessage message)
    {
      _context.Messages.Add(message);
      await _context.SaveChangesAsync();
      
      // 写入Redis消息队列
      await Redis.PublishAsync("chat_messages", message);
    }
}
</pre></div>
<p class="maodian"></p><h3>3. 文件传输</h3>
<div class="jb51code"><pre class="brush:csharp;">public class FileTransferService
{
    public async Task SendFile(string filePath, Socket client)
    {
      using (var fileStream = File.OpenRead(filePath))
      {
            var buffer = new byte; // 1MB分块
            int bytesRead;
            
            while ((bytesRead = await fileStream.ReadAsync(buffer, 0, buffer.Length)) &gt; 0)
            {
                await client.SendAsync(
                  new ArraySegment&lt;byte&gt;(buffer, 0, bytesRead),
                  SocketFlags.None);
            }
      }
    }
}
</pre></div>
<p class="maodian"></p><h2>四、安全机制</h2>
<p class="maodian"></p><h3>1. 通信加密</h3>
<div class="jb51code"><pre class="brush:csharp;">public class SecurityManager
{
    private readonly SslStream _sslStream;

    public async Task EstablishSecureConnectionAsync(Socket socket)
    {
      _sslStream = new SslStream(socket.GetStream(), false);
      await _sslStream.AuthenticateAsServerAsync(serverCertificate);
    }

    public byte[] EncryptData(byte[] data)
    {
      return _sslStream.Encrypt(data);
    }
}
</pre></div>
<p class="maodian"></p><h3>2. 心跳机制</h3>
<div class="jb51code"><pre class="brush:csharp;">public class HeartbeatMonitor
{
    private readonly ConcurrentDictionary&lt;string, DateTime&gt; _sessions = new();

    public void UpdateHeartbeat(string sessionId)
    {
      _sessions = DateTime.Now;
    }

    public bool CheckTimeout(string sessionId, int timeoutSeconds = 30)
    {
      return (DateTime.Now - _sessions).TotalSeconds &gt; timeoutSeconds;
    }
}
</pre></div>
<p class="maodian"></p><h2>五、扩展功能实现</h2>
<p class="maodian"></p><h3>1. 群组管理</h3>
<div class="jb51code"><pre class="brush:csharp;">public class GroupService
{
    public async Task CreateGroup(string groupName, List&lt;string&gt; members)
    {
      var groupId = Guid.NewGuid().ToString();
      await _redis.HashSetAsync($"group:{groupId}",
            new HashEntry[] {
                new("name", groupName),
                new("members", string.Join(",", members))
            });
    }
}
</pre></div>
<p class="maodian"></p><h3>2. 消息撤回</h3>
<div class="jb51code"><pre class="brush:csharp;">public class MessageService
{
    public async Task RecallMessage(string msgId)
    {
      var msg = await _redis.GetAsync&lt;Message&gt;($"msg:{msgId}");
      if (msg != null &amp;&amp; msg.Timestamp &gt; DateTime.Now.AddMinutes(-2))
      {
            await _redis.PublishAsync("recall_message", msgId);
      }
    }
}
