C# socket通讯类

以下是一个简单的 C# Socket 通讯类，可以用于客户端和服务器端的通讯：

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

public class SocketClient
{
    private Socket clientSocket;

    public SocketClient()
    {
        clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
    }

    public void Connect(string ip, int port)
    {
        clientSocket.Connect(new IPEndPoint(IPAddress.Parse(ip), port));
    }

    public void Send(string message)
    {
        byte[] data = Encoding.UTF8.GetBytes(message);
        clientSocket.Send(data);
    }

    public string Receive()
    {
        byte[] data = new byte[1024];
        int length = clientSocket.Receive(data);
        string message = Encoding.UTF8.GetString(data, 0, length);
        return message;
    }

    public void Close()
    {
        clientSocket.Close();
    }
}

public class SocketServer
{
    private Socket serverSocket;
    private Socket clientSocket;

    public SocketServer()
    {
        serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
    }

    public void Bind(string ip, int port)
    {
        serverSocket.Bind(new IPEndPoint(IPAddress.Parse(ip), port));
    }

    public void Listen(int backlog)
    {
        serverSocket.Listen(backlog);
        clientSocket = serverSocket.Accept();
    }

    public string Receive()
    {
        byte[] data = new byte[1024];
        int length = clientSocket.Receive(data);
        string message = Encoding.UTF8.GetString(data, 0, length);
        return message;
    }

    public void Send(string message)
    {
        byte[] data = Encoding.UTF8.GetBytes(message);
        clientSocket.Send(data);
    }

    public void Close()
    {
        clientSocket.Close();
        serverSocket.Close();
    }
}

使用示例：

客户端：

SocketClient client = new SocketClient();
client.Connect("127.0.0.1", 8888);
client.Send("Hello, server!");
string message = client.Receive();
Console.WriteLine("Received message: " + message);
client.Close();

服务器端：

SocketServer server = new SocketServer();
server.Bind("127.0.0.1", 8888);
server.Listen(10);
string message = server.Receive();
Console.WriteLine("Received message: " + message);
server.Send("Hello, client!");
server.Close();
