C#（winform）程序Demo，要求用线程池实现SOCKET通讯，有服务端和客户端。

using System;using System.Net;using System.Net.Sockets;using System.Text;using System.Threading;namespace SocketDemo{    static class Program    {        static void Main(string[] argv)        {            Socket sktltn = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);            sktltn.Bind(new IPEndPoint(IPAddress.Any, 12345));            sktltn.Listen(30);            while (true)            {                Socket sk = sktltn.Accept();                ThreadPool.QueueUserWorkItem(p =>                {                    Socket skc = (Socket)sk;                    byte[] array = new byte[10240];                    int offset = 0;                    while (true)                    {                        int len = skc.Receive(array, offset, array.Length - offset, SocketFlags.None);                        if (len == 0)                        {                            break;                        }                        offset += len;                    }                    string content = Encoding.UTF8.GetString(array, 0, offset);                    Console.WriteLine("> " + content);                }, sk);            }        }    }}

把这段另起一个线程就不会阻塞ui线程了
C# code
new Thread(new ThreadStart(delegate{Socket sktltn = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);            sktltn.Bind(new IPEndPoint(IPAddress.Any, 12345));            sktltn.Listen(30);            while (true)            {                Socket sk = sktltn.Accept();                ThreadPool.QueueUserWorkItem(p =>                {                    Socket skc = (Socket)sk;                    byte[] array = new byte[10240];                    int offset = 0;                    while (true)                    {                        int len = skc.Receive(array, offset, array.Length - offset, SocketFlags.None);                        if (len == 0)                        {                            break;                        }                        offset += len;                    }                    string content = Encoding.UTF8.GetString(array, 0, offset);                    Console.WriteLine("> " + content);                }, sk);            }})).Start();
