关于用线程Socket通信

MSDN 的例子
服务端：
using System;
using System.Net.Sockets;
using System.Text;public class TcpTimeServer {    private const int portNum = 13;    public static int Main(String[] args) {
        bool done = false;
        
        TcpListener listener = new TcpListener(portNum);        listener.Start();        while (!done) {
            Console.Write("Waiting for connection...");
            TcpClient client = listener.AcceptTcpClient();
            
            Console.WriteLine("Connection accepted.");
            NetworkStream ns = client.GetStream();            byte[] byteTime = Encoding.ASCII.GetBytes(DateTime.Now.ToString());            try {
                ns.Write(byteTime, 0, byteTime.Length);
                ns.Close();
                client.Close();
            } catch (Exception e) {
                Console.WriteLine(e.ToString());
            }
        }        listener.Stop();        return 0;
    }
    
}
客户端：
using System;
using System.Net.Sockets;
using System.Text;public class TcpTimeClient {
    private const int portNum = 13;
    private const string hostName = "host.contoso.com";    public static int Main(String[] args) {
        try {
            TcpClient client = new TcpClient(hostName, portNum);            NetworkStream ns = client.GetStream();
            
            byte[] bytes = new byte[1024];
            int bytesRead = ns.Read(bytes, 0, bytes.Length);            Console.WriteLine(Encoding.ASCII.GetString(bytes,0,bytesRead));            client.Close();        } catch (Exception e) {
            Console.WriteLine(e.ToString());
        }        return 0;
    }
