=== 服务器端实现 ===
以下是一个简单的TCP服务器示例，监听本地端口8080并接收客户端消息：

<syntaxhighlight lang="csharp">
using System;
using System.Net;
using System.Net.Sockets;
using System.Text;

class TcpServer
{
    static void Main()
    {
        // 1. 创建Socket对象
        Socket serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        
        // 2. 绑定IP和端口
        IPEndPoint endPoint = new IPEndPoint(IPAddress.Any, 8080);
        serverSocket.Bind(endPoint);
        
        // 3. 开始监听，最大连接数为10
        serverSocket.Listen(10);
        Console.WriteLine("服务器已启动，等待连接...");
        
        // 4. 接受客户端连接
        Socket clientSocket = serverSocket.Accept();
        Console.WriteLine($"客户端已连接: {clientSocket.RemoteEndPoint}");
        
        // 5. 接收数据
        byte[] buffer = new byte[1024];
        int bytesRead = clientSocket.Receive(buffer);
        string receivedMessage = Encoding.UTF8.GetString(buffer, 0, bytesRead);
        Console.WriteLine($"收到消息: {receivedMessage}");
        
        // 6. 发送响应
        string response = "消息已接收";
        clientSocket.Send(Encoding.UTF8.GetBytes(response));
        
        // 7. 关闭连接
        clientSocket.Close();
        serverSocket.Close();
    }
}
