上位机与通信组件（三）

1、基于C#的以太网通信对象

using System.Net.Sockets;

2、socket服务启动监听

# region Socket TCP 服务端
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); // 创建Socket对象
socket.Bind(new IPEndPoint(IPAddress.Any, 9000)); // 绑定ip地址和端口   IPAddress.Any 127.0.0.1
socket.Listen(); // 启动服务监听
#endregion

3、socket服务接收消息

List<Socket> clientList = new List<Socket>();

Task.Run(() =>
{
    while (true)
    {
        Socket client = socket.Accept(); // 同步
        clientList.Add(client);
        Task.Run(() =>
        {
            while (true)
            {
                // 接收到一个消息后 转发出去
                byte[] buffer= new byte[1024];
                client.Receive(buffer); // 卡线程
                string msg = Encoding.UTF8.GetString(buffer);
                msg = msg.Replace("\0", "");
                Console.WriteLine($"从客户端接收到：{msg}");
                msg += "- 服务端发送";
                client.Send(Encoding.UTF8.GetBytes(msg));
            }
        });
    }
 });
