C# Socket 简易的图片传输

以下是一个简单的 C# Socket 图片传输的示例代码：

服务器端：

using System;
using System.IO;
using System.Net;
using System.Net.Sockets;

class Program
{
    static void Main(string[] args)
    {
        // 创建一个监听 Socket
        Socket serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        serverSocket.Bind(new IPEndPoint(IPAddress.Any, 8888));
        serverSocket.Listen(10);

        Console.WriteLine("等待客户端连接...");

        // 接收客户端连接
        Socket clientSocket = serverSocket.Accept();

        Console.WriteLine("客户端已连接");

        // 接收图片数据
        byte[] buffer = new byte[1024];
        int count = clientSocket.Receive(buffer);
        MemoryStream ms = new MemoryStream();
        ms.Write(buffer, 0, count);

        // 持续接收图片数据，直到接收完毕
        while (count == buffer.Length)
        {
            count = clientSocket.Receive(buffer);
            ms.Write(buffer, 0, count);
        }

        Console.WriteLine("图片接收完毕，共接收 " + ms.Length + " 字节数据");

        // 保存图片到本地磁盘
        FileStream fs = new FileStream("test.jpg", FileMode.Create);
        ms.WriteTo(fs);

        Console.WriteLine("图片保存成功");

        // 关闭 Socket 和文件流
        clientSocket.Close();
        fs.Close();

        Console.ReadKey();
    }
}

客户端：

using System;
using System.IO;
using System.Net;
using System.Net.Sockets;

class Program
{
    static void Main(string[] args)
    {
        // 创建一个连接 Socket
        Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        clientSocket.Connect(new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8888));

        Console.WriteLine("连接服务器成功");

        // 读取图片数据
        FileStream fs = new FileStream("test.jpg", FileMode.Open);
        byte[] buffer = new byte[1024];
        int count = fs.Read(buffer, 0, buffer.Length);

        // 发送图片数据
        while (count > 0)
        {
            clientSocket.Send(buffer, 0, count, SocketFlags.None);
            count = fs.Read(buffer, 0, buffer.Length);
        }

        Console.WriteLine("图片发送完毕，共发送 " + fs.Length + " 字节数据");

        // 关闭 Socket 和文件流
        clientSocket.Shutdown(SocketShutdown.Both);
        clientSocket.Close();
        fs.Close();

        Console.ReadKey();
    }
}

注意：这只是一个简单的示例，实际应用中需要考虑异常处理、数据分片、数据加密等问题。
