潜行与窦道的图片:SOCKET编程资料

我选第一个题目，这是服务器端，用c#实现的（VS2005）：
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.Threading;
using System.Net.Sockets;

namespace conNetWorkServer
{
class Program
{
static void Main(string[] args)
{
Socket client;
Socket ServerSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);
byte[] addbyte = { 127, 0, 0, 1 };
IPEndPoint add = new IPEndPoint(new IPAddress(addbyte), 5050);
ServerSocket.Bind(add);
ServerSocket.Listen(3);

while (true)
{
Thread.Sleep(100);
if ((client = ServerSocket.Accept()) != null)
{
Console.WriteLine("连接上...发送数据....")；
byte[] message = { 49, 50, 51, 52, 53, 54, 0 };
client.Send(message);
Console.WriteLine("结束.")
client.Close();
break;
}

}

}
}
}
这是客户端：
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.Threading;
using System.Net.Sockets;

namespace conNetWorkClient
{
class Program
{
static void Main(string[] args)
{

Socket Server = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);
byte[] addbyte = { 127, 0, 0, 1 };
Server.Connect(new IPAddress(addbyte), 5050);
byte[] buffer = new byte[255];
if (Server.Receive(buffer) > 0)
{
Console.WriteLine("连接上...");
Console.WriteLine("从服务器接收数据...");
Console.WriteLine(buffer.ToString());
Console.WriteLine("连接断开...");
Server.Disconnect(false);
Server.Close();
}

}
}
}
