c# socket编程框架

在C#中，使用Socket类可以进行Socket编程，进行网络通信。下面是一个基本的C# Socket编程框架示例：

using System;
using System.Net;
using System.Net.Sockets;
using System.Text;

public class SocketFramework
{
    private Socket serverSocket;
    private Socket clientSocket;
    private byte[] buffer;

    public void StartServer(string ipAddress, int port)
    {
        try
        {
            // 创建服务器Socket
            serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

            // 绑定IP地址和端口号
            IPAddress ip = IPAddress.Parse(ipAddress);
            IPEndPoint ipEndPoint = new IPEndPoint(ip, port);
            serverSocket.Bind(ipEndPoint);

            // 监听客户端连接请求
            serverSocket.Listen(10);

            Console.WriteLine("Server started. Waiting for client connection...");

            // 接受客户端连接
            clientSocket = serverSocket.Accept();

            Console.WriteLine("Client connected.");

            // 开始接收消息
            buffer = new byte[1024];
            clientSocket.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(ReceiveCallback), null);
        }
        catch (Exception e)
        {
            Console.WriteLine("Error: " + e.Message);
        }
    }

    public void ConnectToServer(string ipAddress, int port)
    {
        try
        {
            // 创建客户端Socket
            clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

            // 连接服务器
            IPAddress ip = IPAddress.Parse(ipAddress);
            IPEndPoint ipEndPoint = new IPEndPoint(ip, port);
            clientSocket.Connect(ipEndPoint);

            Console.WriteLine("Connected to server.");

            // 开始接收消息
            buffer = new byte[1024];
            clientSocket.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(ReceiveCallback), null);
        }
        catch (Exception e)
        {
            Console.WriteLine("Error: " + e.Message);
        }
    }

    private void ReceiveCallback(IAsyncResult ar)
    {
        try
        {
            // 接收消息并处理
            int receivedBytes = clientSocket.EndReceive(ar);
            string message = Encoding.ASCII.GetString(buffer, 0, receivedBytes);
            Console.WriteLine("Received message: " + message);

            // 继续接收消息
            buffer = new byte[1024];
            clientSocket.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(ReceiveCallback), null);
        }
        catch (Exception e)
        {
            Console.WriteLine("Error: " + e.Message);
        }
    }

    public void SendMessage(string message)
    {
        try
        {
            // 发送消息给服务器或客户端
            byte[] data = Encoding.ASCII.GetBytes(message);
            clientSocket.Send(data);
            Console.WriteLine("Sent message: " + message);
        }
        catch (Exception e)
        {
            Console.WriteLine("Error: " + e.Message);
        }
    }

    public void CloseConnection()
    {
        // 关闭连接
        clientSocket.Close();
        serverSocket.Close();
        Console.WriteLine("Connection closed.");
    }
}

这个框架示例包含了一个`SocketFramework`类，其中包括了服务器端和客户端的基本操作。你可以使用`StartServer()`方法启动一个服务器，监听客户端连接；使用`ConnectToServer()`方法连接到一个服务器；使用`SendMessage()`方法发送消息给对方；使用`CloseConnection()`方法关闭连接。

需要注意的是，这只是一个基本的Socket编程框架示例，你可以根据自己的实际需求进行扩展和完善。同时，Socket编程涉及到网络通信的复杂性，还需要处理错误和异常情况，确保代码的健壮性和稳定性。
