asp.net小记之——线程

2012年10月26日,星期五

 

线程池*

TCP和UDP的区别*

 

手动创建线程：

    Thread thread = new Thread(new Thread.Start(DemoMethod));
    thread.IsBackground = true;
    thread.Name = "xqt";
    thread.Priority = ThreadPriority.Highest;//设置线程的级别
    thread.Start();

    static void DemoMethod()
    {
        Console.WriteLine(Thread.CurrentThread.ManagedThreadId);
    }

 

Socket通信的模型：

    服务器端：
        -创建Socket：寻址方式，传输的方式，协议————只负责接听
        -绑定一个Host地址和端口：端口同一时间只能被一个进程占用；
        -开启侦听:Linsten();
        -接收用户的请求:Accept()；————创建一个新的通信套接字；
        -客户端关闭Socket时，就关闭了通信Socket；
    客户端：
        -创建Socket
        -连接到服务器端——指定IP和端口
        -与服务器端新创建的套接字进行通信
        -可进行Send和Recive了
        -客户端可调用SocketShutdown关闭Socket
        -直接Socket.Close()关闭时，服务器端会报异常，除非手动关闭；

 

//socket通信模型，服务器端
            - Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            - IPAddress ipAddress = IPAddress.Parse("127.0.0.1");
            - IPEndPoint endPoint = new IPEndPoint(ipAddress, 8888);
            - socket.Bind(endPoint);
            - socket.Listen(10);

//客户端：
           - Socket clientSocket = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
           - IPEndPoint endPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"),8888);
           - clientSocket.Connect(endPoint);

 

SocketHelper:

public class SocketHelper
    {
        //创建服务器端socket
        //创建一个监听一个ip和端口的socket
        //传递两个参数：ip，端口号
        public static Socket CreateListenSocket(string ip,int port)
        {
            if(string.IsNullOrEmpty(ip) || port>65535 || port < 0)
            {
                return null;
            }
            Socket socket = new Socket(AddressFamily.InterNetWork,SocketType.Stream,ProtocolType.Tcp);
            IPAddress ipAddress = IPAddress.Parse(ip);
            IPEndPoint endpoint = new IPEndPoint(ipAddress,port);
            socket.Bind(endpoint);
            socket.Listen(10);
            return socket;
        }
        //客户端连接服务器
        public static Socket ConnectServer(string ip,int port)
        {
            Socket clientSocket = null;
            try
            {
                clientSocket = new Socket(AddressFamily.InterNetWork,SocketType.Stream,ProtocolType.Tcp);
                IPEndPoint endPoint = new IPEndPoint(IPAddress.Parse(ip),port);
                clientSocket.Connect(endPoint);
            }
            finally
            {
                //记录日志
            }
            return clientSocket;
        }
    }
