Socket学习
服务器端代码：(ctrl + shift + space 重载 ctrl + k+ s 外侧代码)
//第一个参数寻址方式 第二个参数是数据传输方式 第三个是传输协议
Socket socket = new Socket(AddressFaimly.InterNetwork,SocketType.Stream, ProtocoType.Tcp);
//绑定端口和IP
socket.Bind(new IPEndpoint(ipstring,portNum));
//侦听
socket.Listen(10);
//线程池创建线程:由于socket.Accept会阻塞主线程，所以开启一个新线程
ThreadPool.QueueuerworkItem(p=>{
Socket serversocket = (Socket) p;
while(true)
{
//接受客户端连接，返回客户端通讯socket
Socket proxSocket = socket.Accept();
WriteText("有客户端连接",proxsocket.RemoteEndpoint.Tostring());
Task task = new Task(s=>{
//客户端通讯socket
Socket pSocket = (socket)s;
while（true）
｛

{
byte[] buffer = new byte[1024*1024];

//客户端正常退出，返回一个空字节
